Looking forward to the 2017 Mind Sports Olympiad, including a Sudoku and Kenken contest

Mind Sports Olympiad medalsOK, I do a post like this one every year, but it’s better than there not being an event to post about. (This year, I’ll even remember to put the tags back in.) If it’s the week before the August Bank Holiday, it’s time for the annual Mind Sports Olympiad. This will be the twenty-first installment of the annual mental-games-and-skills-themed multi-sports festival. This year’s event started on Sunday 21th August and will be running until Monday 28th August and is held at JW3, the London Jewish cultural centre. (Accordingly, there is no play on the evening of Friday 25th or at all on Saturday 26th, being the Sabbath.) This is the first time that the traditionally vagabond festival has stayed in the same location for four years running.

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.

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 27th 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 has won the contest for the last two years 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 Mark’s write-up to get a better feel of what it’s like in practice.

Changing the subject a little, but only a little, I touched upon the Mind Sports Olympiad and the topic of getting puzzle events at wider mind sports festivals a few months back in a “How would we get puzzles at the Olympic Games?” post, touching upon hypothetical possible membership of the World Puzzle Federation within the International Mind Sports Association. With this in mind, I note that the IMSA recently put a new set of statues in place. Section 7.2 has a clear checklist of criteria to meet:

  • History – the IF shall be fully operating for a minimum of six years;
  • Universality – the IF must have at least 40 national federations on at least 4 continents and be not dependent on any specific language;
  • Practicing skilled competitions only – there may be no luck factor in determining the competition outcome;
  • Regularly held national, regional, and international competitions;
  • Well-established rules governing the practice of each sport and mechanism to ensure the application of the rules;
  • Clear and consistent criteria of the eligibility for competitions;
  • Compliance with the General Principle of the Olympic Charter and with the IOC Code of Ethics;
  • Compliance with the World Anti-Doping Agency anti-doping code;
  • Adoption of the principle of the arbitration of the Court of Arbitration of Sport (CAS).

There’s also a section 10 about potential “Associate Member” status, and I reckon that the WPF could take Associate Membership up almost straight away if it wanted to, not being too far from ticking all the boxes above. It’s fun to think about other mind sports which might or might not choose to apply; Scrabble is arguably the most obvious omission from the IMSA, possibly requiring some duplicate format to get around the “no luck factor” stipulation, but the “universality” criterion could be argued to have been directly aimed at the World English Language Scrabble® Players Association and its counterparts.

Section 10.4 of the IMSA statues reads An associate member shall contribute to the IMSA finance by payment of its annual dues and other charges as deemed necessary by the Executive Committee, and that perhaps might be the most convincing reason for the WPF not to join…!


  1. How would you remove the luck factor from Scrabble? I think you’d have to fundamentally change the system to make it devoid of luck. As soon as you play someone you have to have different tiles and I can’t see any way of you playing a second “reverse” game because then you’d know what tiles your opponent would get. You could play entirely solo but it would be an odd event.

    You could all play the same board against a computer but I don’t think people would entertain that idea.

    Any other ideas?

    • A moderately large, but not infeasible possible change: the order in which the 100 tiles are drawn out is made available to both players in advance. Both players get to study this tile order for a few minutes and then one player (effectively, “white” in chess terms, with tournaments trying to even out the number of starting advantages between players) gets to choose whether he wants to play first or second. The strategy changes somewhat as you’ll know just how many tiles you want to play in order to pick up the tiles you want, or leave the tiles you don’t want, rather than going on balance of probabilities, but it’d be close enough for jazz.
