UK Puzzle Association

There are 7 pages in the competition PDF, yes.

Fred is correct on both counts.

Sudoku Xtra 20 is available now from Amazon, or as a downloadable PDF from http://www.sudokuxtra.com . It features a wide range of puzzle types and Sudoku variants, which include Arrow Sudoku, Worm Sudoku, Anti-King Sudoku, Quad Clue Sudoku, Argyle Sudoku, Frame Sudoku, Little Killer Sudoku, Extra R...

Thirdly, "Non-Consecutive Corner Sudoku" also goes by the name "Diagonally Non-Consecutive Sudoku", which is perhaps marginally clearer in conveying what the rules are. Oh, I hadn't come across the variation before so didn't know it had already been named differently elsewhere. As you would expect ...

My post was originally a reply to the one now posted below it. Never mind.

While I watched the opening ceremony I made a special puzzle to celebrate the Olympics coming to the UK: http://www.puzzlemix.com/share.php?id=16340 The bit where the teams came in was quite dull and took ages, so during that period I made the instruction booklet for the forthcoming UKPA 2012 Sudoku...

This is the first puzzle contest I've taken part in for ages and I really enjoyed it - a great set of puzzle types, I think. Also the live verification of submission keys is fantastic.

Hi, it's possible that's in "Paint by 3" a 3 is not shaded?? I stay on this puzzle a lot and i don't find other solutions The puzzle is valid and there is a unique solution which agrees with all of the rules. I'll publish the full solutions once the tournament closes, after the weekend. I'm afraid ...

Just to say that I thought the puzzles in the Sudoku competition were very enjoyable. Can't say much more here, but came to my office late last night to compete. During round 2, I was interrupted several times by Queen's University security, and was kicked out altogether at some stage of round 3. S...

I apologise for the slow handling of key submission issues due to the fact that I was away in Manchester over the weekend. All missing points should now have been awarded. If you are still missing points you believe you deserve, please use the comment option at the bottom of the results page for the...

The third round of the Puzzle Championship will be available online from 5:30pm today (18 minutes from now as I write). Please be sure you have downloaded the updated puzzle PDF before you start. (Puzzle 3:9 is now crossed out - I have left the page in in order to avoid confusion for those who have ...

There will now be no puzzle 3:9 - the first Country Road in round 3 of the puzzle championship, since the puzzle prepared for the competition has turned out to be broken. I have delayed the start of the third puzzle round online until Monday when I am back from the on-site tournament in Manchester a...

That rule is implied by the example, but not stated.

The path CAN cross itself.

The first example in the Team round says "3 puzzles" next to it. Is this a typo, or do all 3 have to be solved? There are 3 different puzzles, all to be solved. However if all teams are having trouble I might relax this during the competition. (but all 3 have been test solved in reasonable times) A...

Not sure if you're intending to compare the on-site results with the online results in any way? The time needed for onliners to print out the questions and then calculate, enter and submit the answer keys will add up to a few extra minutes, which might be more noticeable in the speed 30 minute roun...

Often instruction books are full of small and trivial cases, but in this case there are good quality puzzles being used as examples. Which bodes well for the tournament! I particularly enjoyed Star Battle, Hashi, and Paint By 3. Perhaps they were real puzzles that didn't make the final cut? Anyway,...
