UK Puzzle Association

You won't need a laptop - it just means that puzzles will be on the projection screen.

There is a huge 8 page pull-out of my puzzles in the Sunday Express today, which features lots of different types of content - not just logic puzzles like star battle, but word and other puzzles too. If you go near a newsagent, take a look! :) (or read it free on the iPad app if you haven't previous...

I think it's fair to say that the hints should be sufficient for anyone!

I'll be there at 7pm tomorrow.

I'm going to come along - never been before, but sounds interesting!

You need to scroll the image to the right to see the fifth image.

Ah, yes, thank you - I was counting that shaded square itself as part of the count! Duh.

Just had a look at this. The true/false snake example has an alternative solution which dispenses with the bend at the top-left, unless I'm missing a rule?

I guess they didn't send any emails out for this either. Shame, because if I'd known about it just a day earlier I could have arranged things so as to have taken apart.

IMPORTANT ANNOUNCEMENT REGARDING EARLY FINISHING BONUSES After some consideration, a partial bonus system will be in force for this competition. Solvers who finish early with 15/16 correct answers will score a partial bonus of 1 point for each 30 seconds saved (equivalent to 1/3 of the finishing bo...

Sounds fun, so I'm interested.

I added a few more pictures to the Facebook page too. I couldn't add them to the album but they show up if you view the page itself.

Instructions for round 2 of the Sudoku tournament.

We did it last year and it doesn't seem to have encouraged additional people to sign up this year, so apparently not... I think Liane's compiled a wide selection of puzzles from many top authors so anyone who doesn't come is genuinely going to miss out. If you're in the UK (or can get here easily, e...

I have two suggestions. If they're new to doing logic puzzles and so on then I'd recommend starting with Kids' 10-minute Brain Workout - http://www.amazon.co.uk/Kids-10-Minute-Brain-Workout-Brain-Training/dp/190515853X . This features very small and easy Masyu, Hashi, Slitherlink and other 'Japanese...

I too spent ages on the Rock-Paper-Scissors puzzle, which looked easy but completely stumped me. On that puzzle, if you start on the bottom-left square (which was also where the example solved from, so a natural place to start, and also by inspection the most constrained part of the puzzle) then th...

I really enjoyed the UKPC - overall I personally thought it was better than the USPC, and a really solid test. Thanks to Alan and all of the authors and testers. I particularly enjoyed the Tilt Maze (definitely my favourite puzzle), and I thought the Crypted Fence and Heyajilin were particularly cle...

Just had a look at the solutions and saw how many I got wrong, including just a tiny corner of the fences variation and even one of the spot the differences (didn't mirror the hippo's foot correctly so entered wrong cell). Might end up with less than 100. Oops. Mistakes with the rules too, such as I...

For once - not a "mitigated disaster" - just one answer key put in back to front - fingers crossed there. If OK, then 195. I've seen it suggested that one Roger Barkan, who has finished third at three WPCs, got a provisional 194 this year, so 195 is spectacular! The pre-appeals top US results that ...

Actually this isn't true - when the test started a new page with just the instructions password on appeared.

And as a corollary to that, this means YOU MUST FETCH THE INSTRUCTIONS PASSWORD BEFORE 6PM (UK) TODAY since they are on the same page! Otherwise the site will consider you to have started the test.

Yes, discussion now is absolutely fine! :) Congratulations to the winners, and I have to say I'm so impressed with the standard of solving - in particular for the 6/7 who finished all of the puzzles I think that's a phenomenal achievement! Thanks again also to Thomas Snyder for testing all of the pu...

Great range of puzzles! Are there extra constraints not listed or is LURUDLU an alternative solution to example 5? This path is shorter than the example but has an equal number of tilts so I think it is equally correct? Or does the constraint-based nature mean there will be no unique solution to thi...

Stefano, sounds like your printer didn't handle the instruction to draw dashed lines. If you have trouble with the competition file then try right-clicking the download link and saving and then manually opening in Adobe Reader. You can also always (on Windows) zoom the puzzle you want in the documen...
