Coming up this spring

a series of metal springs making up the word "love"In springs, a young man’s fancy lightly turns to thoughts of love“, as Lord Tennyson absolutely definitely meant to write. Over here, I’ll be attempting to convince myself that winter might be about to be coming to a conclusion, perhaps, by listing some events and insisting that they’re happening this spring.

This weekend, it’s the second round of the WPF’s free-to-enter online Puzzle Grand Prix competition, this time hosted by Slovakia. Once again, there will be three separate one-hour papers available, and the instruction booklets are already available. The Class C booklet is set to be an absolute old-school beauty, with puzzles in seven different styles and three examples of each, with varying levels of difficulty. The Class B and A booklets contain puzzles in five different styles; the class B booklet has two examples of each, one longer than the other, and the class A booklet has a single very difficult example of each. Do whichever paper or papers take your fancy. Last time I did about half of Class C in one hour and tackled a few of Class A in another, leaving Class B completely alone, which felt rebellious. Start your hour(s) whenever you like from half-past Friday, finishing by the end of Monday.

As kindly pointed out in a comment last time but also seen elsewhere, the first Galactic Puzzle Hunt is being organised by the wow-I-hope-this-copies-and-pastes ✈✈✈ Galactic Trendsetters ✈✈✈ MIT Mystery Hunt team. This is an online puzzle hunt in what previously would have been called the Australian style but now should perhaps be considered the Australian/Cantabrigian style. Teams of up to ten will be given five online puzzles each day for six days from (reasonably late UK time on) Tuesday 14th March to Sunday 19th March, and have until Thursday 23rd March to submit the answers. The hint system is different to the standardised hints of the Australian hunts, with teams being able to ask limited numbers of yes/no questions of their choice for the help they need, but “Roughly one week into the hunt, we will start giving out additional hints, and we may be more generous with clarifications; we want teams to be able to solve most or all of the puzzles by the end!” This sounds very public-spirited and gets me very excited about taking part.

So that’s something to look forward to in March. For April there will be the third Now Play This games festival. The site is succinct: “Now Play This is a festival of experimental game design, showcasing some of the most interesting games and playful work being made around the UK and the world. It will run for the third time at Somerset House in London from 7-9 April, 2017, as part of the London Games Festival. There’ll be an exhibition of games running throughout, plus special events including a board games afternoon, a strange controllers showcase, and, on Friday, a day for discussion between practitioners. Tickets will be available from February 2017.” Admittedly I’m not aware of anything puzzle- or escape- specific on this year’s agenda quite yet, but the programme is yet to be announced and surely should be up before long; the people behind it are the very best of eggs and the weekend is a very safe bet to be an excellent one whether there is or not.

As for May, the ninth instalment of the DASH puzzle hunt is set to happen on Saturday 6th May. Now there hasn’t been anything absolutely explicit saying “yes, DASH is happening in London” this year, but there are two very strong clues: first, one of this month’s London Puzzled Pint teams was called “Play DASH on 6th May”; second, an exciting and authoritative Facebook comment suggests that much as both London and Manchester in the UK enjoy Puzzled Pint, both London and Manchester may get to enjoy DASH this year. Definitely one for your diary – and, perhaps, you won’t have so far to travel!

Two cheerful things

You can’t have too many cheerful things, especially with the developments in the world this week, so here are two more.

Firstly, the team behind the splendid Room Escape Divas podcast played a pop-up escape room in Canada a while back. The exciting thing is that they did so wearing GoPro head-mounted/chest-mounted cameras, and have edited the four different perspectives on the same room into a video. It’s fascinating to see them play, the room looks fun and the production values in the video are spectacular. Well worth forty minutes of your time:

Secondly, this weekend sees the first leg of the WPF Puzzle Grand Prix season, as discussed in more detail in the previous post. So far I have only solved the Class C puzzles, but they were everything that I hoped for from them. I didn’t get nearly everything solved that I wanted to solve within the time, but I was pleased with what I did get solved. Unusually, when the hour ran out, I kept going on some of the other puzzles just for fun. I felt like I cracked some techniques that might help me in the future should the same (or, at least, similar) puzzles ever crop up again. If amazing yourself with what you are able to achieve during a puzzle contest (be those accomplishments big or small) is the emotional buzz from a puzzle contest, this paper delivered with aplomb. Recommended… and I haven’t even tried the other two available papers yet!

New year, new Puzzle Grand Prix season

World Puzzle Federation Grands Prix 2017 logoThe World Puzzle Federation has launched another year of its annual series of online puzzle competitions! This year sees the fourth Puzzle Grand Prix season, which starts this weekend. (The fifth Sudoku Grand Prix season started two weeks ago.) If you’re sufficiently interested in puzzles to be reading this site, even if you think you only like escape rooms and have never taken the time to enter a puzzle contest before, you should get excited about this season and think seriously about taking part. The puzzles are fun and there’s no charge for taking part.

The name Grand Prix is an allusion to the tradition of motor races, for there are a series of rounds set by teams of setters from different countries; for instance, this weekend’s contest is the Serbian round, the next one will be the Slovakian round and so on. (There are eight rounds in the competition, each four weeks apart, and your overall score in the competition is the sum of your six best round scores.) Each round is available for 3½ days, from 10am GMT on Friday to 10pm GMT on Monday. During that 84-hour window, you can press the “start the timer” button at a point of your choice; you then have an hour to score as many points as you can by submitting answers to the puzzles from that round.

One difference between this year’s contest and that of previous year, is that every competition weekend there will be three parallel competitions in which to participate, each with its own one-hour paper. The three papers are not primarily graduated by difficulty but by the nature of the puzzles involved. Each paper includes puzzles of a variety of different difficulties, with higher credit awarded for puzzles that are expected to take longer to solve.

  • Starting in the middle, “Class B” puzzles are culture-free language-neutral logic puzzles drawn from well-established World Puzzle Championship formats. Typically these will be grid-based constraint-satisfaction puzzles where “the objective is to fill in information on cells in a grid, based on logic or numerical constraints“.
  • “Class A” puzzles may be new types, or new variants, that might be encountered at a World Puzzle Championship, and may be less accessible to people who aren’t familiar with the World Puzzle Championship standards.
  • “Class C” puzzles are “understandable and solvable to a general audience” but are not necessarily language-neutral or culture-free; they might require a little external knowledge, or they might require “you either know it or you don’t” instinct rather than deduction.

The precise types of puzzles in each of the three contests for a round are announced a couple of days before it starts in instruction booklets. Entertainingly, the “Products” puzzle format in the upcoming Class C contest (see C16 to C18 of the instruction booklet) is not a million miles away from a puzzle style that I once constructed a few years ago!

There’s only one other wrinkle and it’s a slightly strange one. If you have played sufficiently many Grand Prix rounds in the past, or if you have been sufficiently successful when you have played in previous Grand Prix competitions, you will be declared a Class B participant and your score for any Class C contest you participate in will be regarded as unofficial. (If you have been particularly prodigiously successful in the past in previous Grand Prix competitions, you will be declared a Class A participant and your scores for both Class A and Class B contests will be regarded as unofficial.) This makes sense in that it means that the leaderboards for all three contestants will not be crammed with the same names – at least, unless a new solver massively overperforms! – but it may be disappointing for those solvers who are forced into a higher class and are most interested in the puzzles in a lower class. The advice has to be to solve the sets of puzzles that look the most fun and don’t worry too much about the classifications.

Nevertheless, this is another very exciting development. You only need to find one hour over the course of a long weekend in order to have a meaningful competitive experience, and you can choose from three different styles of puzzles, making the series more accessible than ever. If you want to dive deeply in, you could solve all three papers if you wanted to. The series is recommended to all readers; the more people who can find the style and level of competitive puzzling fun that’s right for them, the merrier!

A world championship for escape game teams? Red Bull Mind Gamers: Mission Unlock Enoch

Red Bull Mind Gamers: Mission Unlock Enoch, copyright Red Bull GmbH

image copyright Red Bull GmbH

Just over 18 months ago, I reported on a Escape Room Game Jam held at MIT in association with Red Bull and their associated feature film division. Things went quiet and it seemed that the trail had gone cold on this one. The trail has heated back up; it looks like it heated back up a little while ago, but I haven’t seen anyone talking about it, so here goes.

Red Bull Mind Gamers calls itself a “platform for curious minds, with games and challenges to provoke their thinking“, featuring a selection of online puzzles testing strategy, logic, creativity, visual thinking, abstract musical thought and memory to various extents. The “Brain Food” section features articles and interviews on related contemporary mental game topics.

There has been a countdown to the site’s main event, Mission Unlock Enoch, whose self-description of “global competitive mind gaming tournament” is a gussied-up way of saying “sort-of-escape-room world championship”. Hurrah! This is far more exciting and relevant to interests here than anything else recently done by any other purveyor of caffeinated chilled sugary beverages. (Unless you know otherwise…) It’s all tied up with their MindGamers movie, previously referred to in passing as DxM.

25 teams of four will receive paid travel to Budapest in February 2017 to take on the “ultimate mixed reality Escape Room Tournament”, with the overall champions earning a three-day trip to Boston. Wherever you are in the world, you can attempt to win one of four global wild card spaces by attempting to complete this single-player online game as quickly as possible. (Practising the other games on the site might help.) The other 21 spaces are awarded to national champions to parallel national qualifying competitions held in 21 different countries: Singapore, South Korea, the US, Oman, Russia, Ukraine, Turkey, Norway, Switzerland, and a dozen current EU nations, happily including the United Kingdom. Lots of important gaps in the list: Australia, Canada, China, Japan, and so on, but you’ve got to start somewhere.

Accordingly, there is a national qualifying competition in the UK to determine our representative at the world finals. This will take place at Breakout Manchester on December 5th and at Breakout Cardiff on December 7th. “Within 20 minutes, your team of four players will have to connect their mind skills and solve a multi-player mind game in order to ‘unlock’ and leave the room. The fastest team per country gets to enter the final Escape Room in Budapest in 2017.” Each player only gets one try; you’re not allowed to play on more than one team, or to play in more than one location. It’s not clear how the company are planning to avoid spoilers here; procedurally generated puzzles might be one solution that remains reasonably fair in terms of difficulty.

It’s not quite even that simple! In order to get a place at Manchester or Cardiff, you need to rack up a score towards the top of the local chart for the single-player online game. Top scorers there will be invited to pick their team and their time of choice for the qualification day at Manchester and Cardiff. You miiiight be able to get to play in the qualifiers just by turning up on the day even without scoring well at the online game, but this isn’t guaranteed and I wouldn’t risk it.

The overall pattern looks like this: play the online game alone, do well and earn a spot at Manchester or Cardiff, do very well with your team there and win a trip to Budapest, do extremely well with your team in Budapest and win a trip to Boston. (Maybe, just maybe, the prize will be to go to Boston when the MIT Mystery Hunt is on. That would be a neat circle from the location of the original game jam.)

Not much else is known at the moment, except maybe anecdotally from past players. You can read the rules, the FAQ and the terms of participation as .pdf files, but you may get more of an insight by reading the interview with the designers. One open question: who (or, I suppose, what or where) is Enoch and why should Enoch be unlocked?

Inevitably I’ll be hundreds of miles away from anywhere useful, working the day shift on the Manchester qualification day and the night shift on the Cardiff qualification day, but it would be a joy if whoever the UK representatives eventually turn out to be were part of the community. (Or, the other way around, it would be strange if the UK representatives weren’t part of the community, by choice.) We’ll be cheering the UK team on in Budapest in February!

If you do decide to go for it, the very best of luck to you – and please tell all about it on December 8th!

My thoughts on the 2016 UK Puzzle Championship

UK Puzzle Association logoFor this final post in the short season of posts about the UK Puzzle Championship, everything I say below should be taken as being less important than a hearty vote of thanks to everyone at the UKPA for putting the championship together year after year, from the puzzle authors to the test compilers to the system administrators.

It’s easy to criticise a puzzle contest when you feel that you did worse than you deserve because puzzle styles at which you are particularly strong are, in your view, underrepresented. I’m going to do something different; I’m going to criticise this year’s UK Puzzle Championship for overrepresenting puzzle styles at which I was relatively strong.

This time, I did relatively well by being able to apply variants on one technique to several different puzzles. There were a lot of puzzles which essentially relied on adding together a subset of integers 1+2+3+…+n, for some value of n, to meet a given total. (Or, nearly equivalently, adding all those numbers together and deducing what must be missing to reach a given total.) The same technique was required for Bank Note, Last Digit, Sum Skyscapers, Kakuro (more or less) and Sumpix. Some years some puzzle styles are heavily represented; other years, other puzzle styles get lucky.

I don’t think it’s possible for there to be a reference distribution of puzzle styles (which might look like “one of these, one of those, one of the other…”) against which a UK Puzzle Championship would be measured. It’s one of the joys of the world of puzzle competitions that the constituency of possible puzzles from which source material can be drawn is so wide.

The closest to a taxonomy of (even only culture-free, language-neutral) puzzles that springs to mind is a classification put together by Dr. Tom Synder’s The Art Of Puzzles: “number placement puzzles (such as Sudoku and TomTom), object placement (such as Battleships and Star Battle), region division (such as Fillomino and Cave), shading (such as Nurikabe and Tapa), path/loop (such as Slitherlink and Masyu)“. That page gives plenty of other examples of puzzle styles that fall into each of those broad categories. It’s also key to note that even that page notes the number of other puzzle styles that don’t meet that categorisation. Alternatively, look at Mike Selinker and Tom Synder’s amazing Puzzlecraft on puzzle construction, which considers the wider world of puzzles at large; by a certain definition of the purpose of the UK Puzzle Championship, it would be reasonable for the UK Puzzle Championship to focus upon the culture-free language-neutral puzzles that are the World Championship’s focus.

It’s an open question what the UK Puzzle Championship is for. I can think of at least three motivations: to declare a UK champion, to select (part of) a UK team for the World Puzzle Championship and to raise awareness of organised logic puzzle competitions. Of those three, the selection seems to be the most important in practice; there is seldom much mention after the fact of competition winners as being national champions. (I can think of a few exceptions, all of which so far have been done in good taste, but it’s not the most prominent accolade in practice.)

I take a stronger view than most that the UK Puzzle Association should be using the potential to take part in the World Puzzle Championship as a very strong attraction and should be promoting that at every opportunity. Furthermore, I take the (somewhat radical) view that team selection should be through as many different routes as possible, so that more events can be promoted as qualification opportunities as excuses to get the word spread far and wide. I would promote this ahead of the apparent patriotism of making the UK Championship (and the in-person UK Open Championship) as important as possible. Further still, I would go further than most (though not all the way!) towards prioritising using the UK Championship as an awareness-raising tool over using it to be discriminatory at the elite end to crown a champion.

Click on the image for a bigger version of the graph

There have been six UK Puzzle Championships to date; the above graph compares anonymised solvers’ performances on them. The dark blue line represents performances in 2011, the orange line in 2012, the yellow line in 2013, the green line in 2014, the brown line in 2015 and the light blue line in 2016. The horizontal axis represents the position of the solver relative to the cohort (the best performing finisher far left, the worst performing finisher who scored at least one point on the right, the median solver midway and so on) and the vertical axis represents the score of the solver, expressed as a percentage of the nominal perfect score assuming no bonus. Accordingly, an all-correct solution with a time bonus earns more than 100%.

It’s clear that the 2016 competition was relatively difficult, or at least that the quantity of material on the paper was rather higher than in the two previous years. The raw number of points possible were rather higher this year than in previous years; it’s not clear that a, say, 15-point puzzle this year directly correlates to a 15-point puzzle in previous years. The spread of point distributions between relatively low-valued and relatively high-valued puzzles varies considerably from year to year, too.

On the chart above, the data points from 2011 to 2015 have each been marked with a + or a X. Data points marked with + symbols refer to solvers who have participated in the contest in later years. Data points marked with X symbols refer to solvers in their last year of participation. Obviously the participants from 2016 have not been marked either way as it is not clear whether they will participate from 2017 onwards or not. Two conclusions I have drawn:

1) Every year from 2011-2015, there has been at least one top-six solver who hasn’t participated in future years. While you can’t make people participate if the date and time don’t suit, or if their interest in UKPC puzzles has waned, the potential UK team at the WPC would surely benefit strongly from their participation in the UKPC – and I would recommend proactively reaching out to them individually.

2) If you finish in the bottom 20%, you are no more likely (and, in three of five years, strictly less likely) to participate than not to participate in future years. Speaking as a self-certified, long-established “crap ‘un”, there have been years where I’ve been practically (and at least one year where I’ve been literally) the only bottom-feeder to come back and participate in future years. Now perhaps this would have less of an impact on the potential UK team at the WPC, but it doesn’t strike me as an indicator of robust health from metaphorical nose to tail.

The logic puzzle competition hobby in the UK has an unusually skewed distribution of skill levels. We are fortunate enough to have very strong solvers at the top end. The standard of the best solvers, around the world, is improving over time. (Conversely, the highest end of championship play requires increasingly difficult puzzles over time.) The dear Croco-Puzzle site once did an experiment by posing the same, otherwise unremarkable, series of daily puzzles a couple of years apart, and noted an improvement in performances over time.

The standard of the UK’s best solvers varies from year to year, but we certainly have very strong solvers at the top end. I tend to believe that a championship with the same cohort of top solvers at the top end, similar mid-tables and a rotation in the lower order, who try a championship and largely decide that it’s not for them rather than sticking with it and (hopefully!) improving over time, does not represent strong health. There are other mind sports which spring to mind, where there are competitions with the same, very few, extremely strong participants again and again, and no real infrastructure for the less accomplished to play and improve.

I do tend to believe that strong participants are made rather than born, simply by the degree of practice that the best solvers put in. On the other hand, they tend to be found rather than produced; perhaps my biggest hope is that some more people with the UKPC sort of smarts and a strong sense of competition find the championship. I’d really like to try to tap into the well-established mathematics competition infrastructure that keeps the best solvers engaged before university… but relies on university to give them chances to compete after that. Where do past International Mathematics Olympiad students go for their competition fix? In theory it could be the (seemingly similar) International Mathematics Competition for University Students, which happens to be in progress in Bulgaria this week, but in practice it doesn’t seem to be that way for UK universities. Certainly there have been some past IMO participants who’ve translated to the WPC very well; I’d love to try to grab other UK IMO team members to try out for the UKPC, if that were their sort of fun.

That said, the logic puzzle competition hobby is so much better off than it once was; originally, the season was just a single qualifying competition long – and up to 2010, the UK used the unforgiving US Puzzle Championship as that qualifier. The addition of the WPF’s Puzzle Grand Prix represents a considerable improvement, with relatively accessible puzzles included in every contest and a less-daunting 90-minute duration. The addition of the “casual” division to the WPF Puzzle Grand Prix papers represents a second considerable improvement to accessibility, even if it’s an experiment which might not quite have turned out in the way that was intended.

I’ll emphasise again that I offer profound gratitude to everyone at the UKPA for putting the championship together year after year; at the end of the day, it’s for the UKPA to decide their priorities and for them to devise a championship to do what they want to do. I’m not a UKPA member, not least because I know my opinion on this matter is an outlier, and I think it works well for them to do their thing and for me to do my thing separately.

There are, after all, many, many little separate puzzle hobbies – and, by and large, they’re all happy keeping themselves to themselves and doing their own little thing. (Which is not the way I would like it to be, but there is much in life that fits that description.) And yet if there’s one situation where one little self-contained puzzle hobby could do with making itself known to other little puzzle hobbies and trying to tap smart people who throw time and effort into puzzle hobbies, it’s for the purpose of trying to get a strong UK puzzle team together. At heart, this is a big part of the reason why I want to try to bring the little puzzle hobbies together, to try to get more brilliant people trying out for the UK team.

Dr. Gareth Moore puts it really well. Excerpting what he has to say: “The barrier to entry is certainly high, since you need to be familiar with so many different types in order to compete at a certain level. Not that there’s necessarily anything wrong with that – but if the aim is to get new people involved, I would certainly say it’s important to always have a significant number of puzzles that are approachable to anyone. Similarly, it’s important to include puzzles that ‘everyone’ will be familiar with, so the kind of puzzles you might find in a newspaper.

To me, a big part of the aim should be to get new people involved, and that should include a strong representation of familiar puzzle styles, including “casual” puzzles (as opposed to grid-based Constraint-Satisfaction puzzles) such as picture puzzles, wordsearch-style puzzles, numerical puzzles, crossword-style puzzles and insight puzzles, at a genuinely accessible level of difficulty. This year’s UKPC did fit that bill to a limited extent and the UKPC – while I’ve seldom (if ever?) enjoyed it more than I did this year – certainly has done better in this regard in previous years. I’d like to see future UKPCs make that a higher degree of focus, while still remaining the ability to discriminate between the most capable and experienced solvers at the top end of the competition.

And I’d also like the moon on a stick while we’re at it, please…

UK Puzzle Championship 2016: the stats

Latest UK Puzzle Association logoThe second post in the short “UK Puzzle Championship” season is the annual statistics post. The UKPC results have been published and this site congratulates everyone who is happy with their result.

The biggest congratulations of all go to Neil Zussman on his second UK championship after winning three years ago. James McGowan was a strong second place and Tom Collyer picked up a third successive bronze, though finished closer to second than ever before. Globally, these performances (and that of fourth-placed Steve Barge) were very competitive and took some impressive scalps. The number of UK participants on the scoreboard bounced back up to a joint record 25, with seven first-timers this year – and only five solvers on the scoreboard for all six of the UKPCs to date.

As ever, this site continues to update a year-on-year chart of UKPC performances, in the style of Tim Peeters’ charts:

Errors and omissions excepted and corrections are welcome; note that this site declines to split places between players on equal scores on the “time left” tie-breaker. Many thanks to everyone who has been involved with setting the puzzles or organising the contest over the years, especially Liane Robinson and Alan O’Donnell, the most frequent contest compiler and administrator.

Just two more weeks until the eighth and final round of the World Puzzle Federation’s Puzzle Grand Prix!

How to break in to the 2016 UK Puzzle Championship

Latest UK Puzzle Association logoA short “2016 UK Puzzle Championship” season begins with a piece about how to get started with the puzzles in the competition. The piece needs context, however; participants have frequently commented that there weren’t many easy puzzles in the contest, yet participants’ scores tended to skew relatively high, compared to previous years’ contests. It’s also worth pointing out that I tend to come near the bottom of the rankings table, typically beating about 20% or so of the other competitors. Accordingly, take what I say with a considerable pinch of salt – but, on the other hand, there aren’t many people talking about the puzzles. Considerable credit goes to James McGowan for posting links to practice puzzles in advance.

You are strongly recommended to download the puzzles, open them using the password 20_S3n3c_16 and look at them in parallel with this commentary. First and foremost, thanks to the puzzle authors for their contributions and to Liane, Alan and David for putting the contest together and making sure that it happened at all. I thoroughly enjoyed the event.

Can a puzzle contest simulate an escape room?

World Puzzle Federation logoThe World Puzzle Federation‘s rolling Puzzle Grand Prix contest has its fifth round this weekend. It’s a free-to-enter online puzzle contest where you are given an hour and a half to score as many points as you can by solving paper-and-pencil puzzles. You can start at any point after 11am UK time on Friday and must conclude by 11pm UK time on Monday.

This fifth round is particularly interesting to this site because it’s being set by puzzle authors from the US who have chosen to theme some of their puzzles in the “casual” section around what they’re calling “Escape the Grand Prix”. For all intents and purposes, don’t worry about the distinction between the “casual” and “competitive” sections unless you’ve been solving every round and getting almost all the “competitive” puzzles correct; just solve whichever puzzles seem most entertaining, whichever section they’re in.

You are trapped in a room with a stack of puzzles, wondering if you’ll be able ((to)) finish all of them. Between you and the end is one Mastermind puzzle. But it seems to be in code, with twenty different letters corresponding to different digit values from 1 to 9 (e.g., X = 2 or Y = 6). Perhaps solving the other puzzles, some normal in appearance and others with some of the same code letters, will help. Not all puzzles will be useful to crack the code, but you never know where important clues will be found so search everywhere. Can you figure out what digit each letter stands for and ‘Escape the Grand Prix’ before time runs out?

Take a look at the Instruction Booklet which is a 3.3 MB .pdf file; the booklet hints at the sort of tricks it might use to secrete digits’ identities throughout and also shows you what other types of puzzles there will be on offer in the contest. The contest goes out of its way to offer puzzles in a wide range of levels of difficulty, and you know what styles of puzzles will be featured in advance so you can have a good idea whether you’ll enjoy them or not. You can even get some practice in on the types of puzzles that you know you’ll be facing in advance, if you like. The first four rounds were great fun and this one should be even more so!

Coming soon: HIQORA, the High IQ World Championships

High IQ World Championships logoThere’s an interesting and unusual-looking online puzzle contest happening on Saturday 28th May: the first round of the 2016 edition of HIQORA, the High IQ World Championships. It has an interesting structure: there will be two online rounds, with the top scorers from the first advancing to the second and the top 12 scorers from the second winning flights to, and accommodation for, the live world final in San Diego. (No clue if there’s any prize other than the trip and the title, but that’s easily good enough alone.) The first round is set to start at 4pm UK time on Saturday 28th May, and will be held simultaneously around the world, so it starts at 8am in San Francisco, 11am in New York, 6pm in Moscow and so on. (The web site suggests that it starts at 8pm in Beijing, but this may be a typo.) Can’t help feeling that this is even more of an advantage to people operating on European time already, and it does seem a shame that there won’t be many people who get to start at 1pm, 2pm or 3pm, but any time is bound to inconvenience some more than others.

The duration of the first round is yet to be confirmed. “The two Online Rounds will each be up to four hours in length, and held simultaneously around the world. Activities and questions are drawn from the HIQORA Championship Framework which explores multi-disciplinary aspects of high intelligence. Examples of these activities and questions may include: learning to play a new board game; interpreting complex literature and language passages; interactive case studies; mathematics and graphical workouts; spelling bees; memory workouts; knowledge of geographical facts and figures; and various exercises across science, technology, education and maths (STEM).

You may be given the rules to a new board game, or other pre-reading, 72 hours in advance and thus a relatively limited time to master it. That sounds like rather a fun sort of challenge. It’s tempting to wonder whether or not the championships will attempt to be culture-neutral. The signs would seem to point to that not being a top priority, and (at the risk of an interpretation, which this site would love to learn is incorrect) might seem to imply a focus on English language culture. On the other hand, this would appear to be only a small part of the focus of the overall test.

One comment in the FAQ is particularly striking: “(…) it’s important to note that HIQORA is a test of natural intelligence, so study as such is of lesser importance to success in the competition than natural abilities.” This site tends to believe that puzzle contests covered by this site generally tend not to go out of their way to make that sort of distinction, and this is the point at which it’s tempting to get a little cynical about the extent to which a contest truly could separate natural abilities from facility at, and familiarity with, IQ test puzzles. Had this been clearly marketed as, say, “an IQ puzzle championship” then this site would have embraced it with open arms. On the other hand, the wide variety of components to the challenge mean that it seems to be intended to be more than just an IQ puzzle championship. That’s fair enough and probably makes for a more interesting event, but can something culture-specific really be a fair test of natural abilities to people around the world for a true world championship?

By way of full disclosure, I’ve never taken a formal IQ test and Mensa has never seemed appealing to me. That said, the Mensa members I’ve met in person have been thoroughly convivial to a (non-gender-specific) man; when I was taken as a guest by a Mensa member to a Mensa meeting – for that is perfectly possible – I enjoyed my evening there. While I tend to be leery at best when it comes to exclusivity being sold as an inherent virtue, I am thoroughly supportive of the necessarily elitist World Puzzle Championships as adding to the jollity of the world, though much of my favourable opinion comes from the context of the WPF’s outreach and accessibility of its qualification and Grand Prix events.

Whether the trimmings and trappings of the contest appeal, you’ll know whether or not it looks like a fun way to you to spend a few hours. At worst, it would appear to have a lot in common with the sorts of contests and challenges that this site enjoys. While the inflexible timescale may hinder – for instance, I’ll be between night shifts – it’s far from the only contest to have specified a particular timeslot in an attempt to avoid some people getting to see the questions before others. While nominally some people are charged US$40 for participation, several sources online quote HIQORAHighIQ as a code for free entry.

If you take part, this site wishes you well – and please come back and tell us all about it!

Puzzle competitions coming up soon

Selsdon Park HotelThere are exciting puzzle competitions coming up soon, both in person and online. The online contests take place this weekend, the in-person ones next weekend. The online contests are free to enter and you can do so at a time and place of your own choosing; the in-person contest has a specific time and location and fees must be charged to cover the cost of booking it.

The second round of the World Puzzle Federation‘s Puzzle Grand Prix series takes place this weekend. It’s a 90-minute contest, which you can start as soon as 10am on Friday 19th February but which you must complete by 10pm on Monday 22nd February, so you have half a week in which to pick your 90-minute window. (Those times are the ones quoted in theory, the ones in practice may be an hour later.) This set of puzzles has been devised by the Slovak team. As with the previous round, the puzzles have been divided into Casual and Competitive sections, with the Competitive section more traditional constraint-based grid puzzles and the Casual section slightly more freeform, though not necessarily easier. Log in to the GP series web site then download the instruction booklet to find out the types of puzzles in advance, then plan your attack.

If you prefer Sudoku, though, then Logic Masters India have a contest for you this weekend where the puzzles have been devised by Belfast’s David McNeill, the over-50 World Sudoku Champion – and over-50 World Sudoku Champion, too! David has been a mainstay of the UK puzzle scene for well over a decade and is a very experienced puzzle setter, so this promises to be a treat. This weekend’s contest is called Triplets and Triangles; it too is a 90-minute contest, available between Saturday 20th February and Monday 22nd February at times to be confirmed. The contest has 14 puzzles, starting with classic 9×9 sudoku, running through some variants themed as the title of the contest suggests, and ending up with some brand new puzzles that seem to combine two other variants into a single new challenge.

In person, the UK Puzzle Association are running the UK Open tournaments in sudoku and puzzles on 27th and 28th February at the Selsdon Park Hotel near Croydon, pictured above; increasingly this has become the home of puzzles in this country, most famously for being the site at which the UK held the World Championships in 2014. Again the instruction booklets have been posted; most notable is Bram de Laat’s second round, “Two to Five”, with sixteen different puzzles in four general styles: room placement puzzles, split wall puzzles, division/dissection puzzles and number puzzles. In each of those four styles, there’s a puzzle that relies on two-themed properties (pairs of cells, sets of two adjacent rooms, dominoes with two digits and so on…), a puzzle themed around threes, a puzzle themed around fours and a puzzle themed around fives. Delightful design! The event is always highly convivial so do take a look and see if it’s your sort of fun.
