It’s World Championship time

World Puzzle ChampionshipThe 25th World Puzzle Championship, and its younger sibling the World Sudoku Championship, will take place next week in Senec in the Slovak Republic. You can find the details at the official web site. It’s a competition featuring rounds and rounds of culture-free, language-neutral (mostly logic) puzzles. The final version of the instruction booklet has been posted, so you can see examples of the sorts of puzzles that are going to be faced.

I’m not quite energetic enough to do as in-depth a preview as I have done in previous years, but here are some quick notes. The World Puzzle Championship this year will have 25 full national “A” teams, one up from last year; welcome to Austria and Belarus, farewell (hopefully briefly!) to Romania. There will also be participants – if not full teams – from Belgium, Canada and Luxembourg, the first two of which have had podium-placed full teams in the WPC’s early years. With the make-up of sundry “United Nations” teams, as well as nations’ “B” teams (and, unusually, five “C” teams and even a “D” team) there will be fifty teams in total. This is hugely impressive, though it’s to be noted that this means teams are split over a number of different hotels, which is a slightly different way of doing it than most years – though a very practical one. It’s a particular thrill for me to see that Berni and Silke of Croco-Puzzle are getting to play on the German “B” and “C” teams.

The UK team retains Neil Zussman and Tom Collyer from last year, though substitutes in Adam Bissett and Thomas Powell for James McGowan and David McNeill. (David can’t make it to defend his over-50 titles in both sudoku and puzzles; a pity, not least because it neatly blows up one of my predictions.) The UK team would be doing very well to finish in the top ten of national “A” teams this year.

For the last two years, this site has tipped Japan to win and they’ve finished second. The German “A” team is missing Florian Kirch, for the saddest of reasons, and Michael Ley (who finished eighth in the main rounds) is on the German “B” team once again. The Japan “A” team has last year’s champ Ken Endo and last year’s fifth-placed Kota Morinshi, but also has Taro Arimatsu and Hideaki Jo who finished 1st and 3rd in 2010. That’s too scary a line-up to ignore, and thus this site tips Japan once again, and would be prepared to back it up with a small bet at even money.

The Crystal Maze is coming to Manchester

The Crystal Maze logoThe one-off revival of The Crystal Maze is being broadcast on Channel 4 at 9pm this Sunday – perhaps this might be a slightly updated logo, perhaps not – and is apparently set to feature a cheeky cameo or two. It’s been filmed at London’s The Crystal Maze live experience and it’ll be a challenge for a set that is designed to see a couple of hundred players per day match up to the demands of a TV set. It also remains to be seen how the games come across on TV.

Whether it’s a hit or a miss, the live experience has proved such a hit in London that, as previously hinted, a second maze will be opening in Manchester. The Manchester Evening News suggests the location will be the “old Granada studios”, as predicted by a detective on the Bother’s Bar forum. Sales opened today; currently, tickets are available for April 2017; the opening date of April 1st is possibly a tad inauspicious.

There are many similarities to the London site, but a few exceedingly curious differences. It’s still a game for teams of eight, and it’s still closed on Mondays (except Bank Holidays). However, instead of four teams starting at the same time, the starts seem to be staggered at five- and ten- minute intervals, so eight teams start every hour. This has me wondering how this will work. (Is it possible that they plan to build two copies of each zone, just to double throughput? Could they even build two different mazes, with different games for replay value, in parallel?) One interpretation is the possibility that all the teams will play the zones in the same order – or, if the “two copies” hypothesis is correct, conceivably there might be different, but fixed, starting points in the two mazes. Another difference is that the experience is suggested to take two hours, which is longer than the London equivalent. There will be differences and it’ll be a treat to find out what they are.

The pricing has been announced, and games on Tuesdays to Thursdays are £45 per player (plus 5% booking fee). That’s pretty tempting. Earlier this year, I organised for 32 people, mostly site owners and staff but also enthusiasts, to take over The Crystal Maze for an hour, the day after the London edition of the unconference. Should we do it all again in Manchester next year?

Instant reaction from the Unconference in Leeds today

I very much enjoyed my time at the latest “The Great Escape UK” Unconference in Leeds today. There were about 27 attendees by the end of the day; I enjoyed catching up with some from previous events and just as much enjoyed meeting others for the first time, some of whom had been on my “it’d be nice to meet some day” list for quite a while. The venue was Dock 29 in the Leeds Dock area, which looks very smart; while there is a water taxi giving free rides from (very near) the train station, there isn’t a good system for letting people know when the water taxi isn’t running, and sadly this contributed towards me only being able to attend the last four and a bit hours or so. (Unconferences are a little stranger when you can’t attend the planning-on-the-day stage at the beginning… though I probably could have stuck a session note onto the board if there was something burning that I had wanted to discuss.) Jason Stroud of Thinking Outside The Box was the only known person to travel from the UK to Chicago for the Room Escape Conference last month and I was disappointed to miss him presenting his findings; the rest of us will have to settle for this review video.

I believe that organiser Liz Cable will be putting together a more formal description of the sessions at some point, as well as co-ordinating the collation of the notes that people took. After a buffet spread that looked as good as it tasted, Liz took eight or nine of us around her Code-X pop-up game, a few doors down, that sadly has to close on Sunday 18th and clear out shortly after. The aesthetic is distinctive and likely very effective, and there are as many surprises as you’d hope for. A tour can never match up to playing the game for real, but this did look like a treat.

In the afternoon, there was a session on potential for interaction between escape rooms and academia; without wanting to get too “one weird trick” about it, there do seem to be revenue streams that might be able to be tapped by escape room creators who can reframe the advantages of what they offer in ways that universities will want to hear, far aside from the obvious one of having students coming and playing your regular open-to-the-public game. There was also a fascinating session comparing academic models proposed over the years for game players’ motivations, discussing the extent to which they may or may not apply, and giving practical applications of the most promising-looking of these models to the escape room context. Escape game web sites often tend to promote their offerings in fairly similar fashions, which may be relatively generic when something more tailored to differently motivated groups of players may speak more directly to them.

Past unconferences have often generated a spirit of “sure, it would be great to work together!” which has not generated practical activity. The end of the day had some attempts to be slightly more concrete about initiatives which seem to have common purpose: a smarter approach to insurance (are some people paying too much? Do companies’ insurance policies really cover you?) as well as potential to investigate group buying where it makes sense, and places where the industry as a whole might promote itself more usefully than individual brands doing so.

Exciting times! Lots to think about; many thanks to Liz and the attendees for putting the day together. The next unconference will be on Tuesday 10th January 2017 at The Steam Room, part of “Drink, Shop and Do” near King’s Cross Station in London; it too should be a treat and booking is already open. Being the second Tuesday of the month, of course, that will be a Puzzled Pint night, so don’t forget about one really good, relevant opportunity to socialise afterwards!

Puzzle hunts and puzzle competitions right about now

Here Comes The Sun! ...from a T-shirt credited to "Pablo Bustos aka Wirdou"
That rather fun image (adapted, without permission, from this shirt credited to “Pablo Bustos aka Wirdou”) sets the tone for some of the things happening at the moment which may be of interest.

It’s Labor Day, without the u, in the United States today. As he has previously done for nine of the ten previous Labor Days, Mark Halpin has posted an extravaganza: a hunt-like collection of puzzles to solve at home. They are principally word and picture puzzles; Mark has a glorious reputation for setting devious cryptic crossword variants. E-mail individual puzzle answers to Mark for verification; one team who solves within the first two and a half weeks, chosen at random, will win a $25 gift certificate prize. (Alternatively, e-mail Mark for hints and tips.) The theme for this year’s hunt inspires the title of this article.

If this hunt doesn’t fit into your schedule, or if you want a hunt designed for a larger team and with possibly a slightly broader style of puzzles, then a good option is the mezzacotta puzzle competition taking place from Monday 10 October, 2016 onwards. This is the direct descendent of the CiSRA puzzle hunt which gave a great deal of fun to many people over the years. The format is expected to be very similar to the CiSRA hunt, as well as the MUMS and SUMS puzzle hunts of the mathematics societies of Australian universities; many people are looking forward to seeing the precise specifics of the form to be taken by this year’s hunt.

Alternatively, there are some competitions which test the ability of a solver – or a team – to set puzzles, as well as to solve them. This post comes too late to feature timely details of Iron Puzzler of Southern California, just over a week ago, but Germany will be hosting the Puzzle Decathlon competition in Wuppertal (just east of Dusseldorf, so not far from the Dutch border) in November. Some rounds feature puzzles to solve; other rounds see you set puzzles for your fellow competitors!

Unconferences past and future

unconferenceJust quickly:

The second “The Great Escape UK” unconference took place in London on April 25th. People took notes from many of the sessions at the time. A few sessions remain unscribed and attempts to chase the sessions’ scribes have proved fruitless. However, as something is much better than nothing, please enjoy the notes that have survived from most of the sessions; if you are in a position to add to them, please do so.

The third “The Great Escape UK” conference will take place in Leeds on September 6th, also known as next Tuesday; specifically, it will take place at Dock 29 between 11am and 7pm. Take a look at previous unconference coverage on this site to see whether it sounds like your cup of tea; if so, book your ticket now. You’ll need to pay for your ticket at the time of booking because (a) booking includes lunch and (b) there were many people who booked free tickets and didn’t turn up last time, so there were plenty of other people on the waiting list who wanted to go but couldn’t.

This third meet-up for the UK Escape Room Industry welcomes anyone involved in running, designing, or creating Escape Room Games in the UK, or associated industries. We also welcome keen players, as long as they promise not to rip out the fixtures and fittings in search of clues. We also allow suppliers to attend in the spirit of sharing not selling. ((…))

Our quarterly Unconference returns to Leeds. Everyone can propose a session on the day, on anything they like, people signup for whatever tickles their fancy, then the agenda is decided as we go along. ((…))

Some offerings include a report back from the first Chicago Escape Room Conference, and an offering (from me) on Curiosity and Player Motivation and how it impacts Room Design – a summary of a week-long symposium on Game Design at Utrecht University (actually more fun than it sounds).

Unrelatedly, but still excitingly, on the day after the London unconference, 32 escape room owners, staff and players visited the The Crystal Maze attraction in London. Yesterday The Sun suggested (and, today, reports have reached as far as the BBC) that there will be a one-off revival of the show on Channel 4 for their Stand Up To Cancer night on October 21st. There won’t be a full-scale maze made for a single show; Buzzfeed report that the event will be filmed at the attraction in London. This is an extremely spectacular setting for an event you’ve paid tens of pounds to play in person and a somewhat unspectacular setting for a TV show featuring a team of celebrities. We shall see, and hope that it proves a prelude to a full-scale, big-budget soup-to-nuts revival of the series at a later date.

Looking forward to the 2016 Mind Sports Olympiad, including a Sudoku and Kenken contest

Mind Sports Olympiad medalsIf it’s the week before the August Bank Holiday, it’s time for the annual Mind Sports Olympiad, and it’s time for me to roll this post out again. (Don’t worry; this year I’ll add some fresh bits.) This will be the twentieth installment of the annual mental-games-and-skills-themed multi-sports festival. You know how a certain major thing happening in Brazil at the moment, which I choose not to name because you can’t be too careful these days, has some of the world’s most prestigious contests in many different physical sports? The principle behind the Mind Sports Olympiad was to try to emulate that for brain games. The budget has never really been there to attain this at the very top level, but the event has kept going year after year and developed its niche. (Given how careful we are encouraged to be regarding the O-word, you might have thought that the Mind Sports Olympiad was skating on thin ice, but it survives through the traditional use of the word in long-established context, following the pattern of the Chess Olympiad and the Bridge Olympiad.)

Some people prefer to focus their efforts on a single mind sport at the highest level they can attain, others take a much broader view that it’s more fun to compete at many different games, and the Mind Sports Olympiad is a great place for those who take the second viewpoint. This web site has a lot of sympathy with the principle. By analogy, some people like only exit games, others only logic puzzle contests, others only cryptic crosswords or mechanical puzzles or geocaching or one of maybe a dozen other things; this site tends to believe that if you like one but haven’t been exposed to the others then it may well be that you turn out to enjoy the others as well.

This year’s event runs from Sunday 21st August to Monday 29th August and is held at JW3, the London Jewish cultural centre. (Accordingly, there is no play on the evening of Friday 26th or at all on Saturday 27th, being the Sabbath.) The most immediately relevant event to readers of this site is the contest in sudoku and kenken (also known as calcudoku – think killer sudoku, but with other mathematical operations as well as addition) on the morning of Sunday 28th August, which this year has £140 of prize money provided by sponsors. However, there are contests in scores of other mind sports as well, plus an open play room with a well-stocked games library open each day. You might well recognise some of the attendees.

Neil Zussman won the contest last year and Mark Goodliffe won the contest for each of the last two years before that, so expect competition to be fierce – but if the event sounds interesting at all, you can read his write-up to get a better feel of what it’s like in practice. Perhaps the You-Know-What taking place at the moment are putting you in a competitive mood!

As a side note, another particularly interesting event at the MSO is the Decamentathlon, a three-and-a-half-hour test of skills in ten different mental events. (The memory test involves a physical pack of cards and a long number to memorise, the rest can reasonably be compared to written exam papers.) Originally the ten skills tested were bridge, chess, creative thinking, draughts 8×8 (“checkers” if you’re from the US), go, intelligence, mastermind, memory skills, mental calculations and othello, but these have varied over the years. This year, bridge, mental calculations and othello are out; backgammon, sudoku and kenken are in. If this appeals, Thursday morning will let you try to win the game of many games!

Lastly, The Guardian are posting puzzles every fortnight, though they don’t make you hang around for the answers; the most recent set is nicely thematic.

Puzzle e-books for charity donations

The Maze of Games front cover, copyright Lone Shark Games

You probably know about this already, but just on the off-chance you hadn’t heard about it:

Humble Bundle currently have a bundle of puzzle e-books available. Humble Bundle work on a “pay what you want, and you can choose to donate it to a charity of your choice” system; as far as I can tell, any charity with a UK charity number is eligible for your donation, though I like the look of the three defaults which are suggested.

Pay/donate US$1 or more and you receive links to download .pdf versions of seven books, notably including “Logical Leaps and Landings: An Adalogical Ænigmas Collection” by Pavel Curtis, descirbed as follows: “Think you’re up for a truly serious test of your logical-reasoning powers? Every month, Augusta Ada King, Countess of Lovelace, often credited at the world’s first computer programmer, presents to the solving public (with clerical assistance from Pavel Curtis) a new logical “ænigma”. This book collects the first two years of Ada’s series, 24 logic puzzles ranging from challenging to exceedingly difficult. Each puzzle is accompanied by author commentary and a full solution, along with explanations of how to read any Easter eggs that Ada might have concealed somewhere on the page. NEW FOR THIS BUNDLE.”

Pay/donate US$7 or more and you get eight more books in the same way for a total of fifteen, headlined by Dr. Thomas Snyder’s “The Art of Sudoku” and Mike Selinker’s “The Maze of Games”. Increase your payment/donation to US$15 and up for a total of twenty-one books plus the audiobook version of “The Maze of Games” and one more, containing puzzles pointing to hints to a super-meta for “The Maze of Games”, once it is written in a couple of months’ time. Increase your payment/donation to US$42 or more and US$25.01 of it will cover the cost of a hardback copy of “The Maze of Games”, but you have to pay shipping on top… and shipping a hardback book overseas is seriously expensive, raising the effective price past the GBP 50 mark.

Being cynical to a fault, it looks like several of these books could not actually have previously been bought as dead-tree books (except possibly via print-on-demand services…?) and it’s possible that several of the puzzles may well have been published elsewhere previously, but you’re still getting an awful lot of high-quality puzzles for a remarkably low cost…. which could be entirely a charity donation if you wanted it to be one. The star attraction is probably “The Maze of Games”, and it’s likely that you might have backed it when the Kickstarter campaign was in progress. However, if you didn’t, you can get a wealth of wonderfully well-realised ideas at an extremely attractive price.

Highly recommended!

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.
