Re: UKPA Open Sudoku and Puzzle Tournament 2024
Thanks Liane. That is not the answer I expected. It makes the constraint rather weak for long lines. Liane has emailed an update on this answer to those attending, as follows: "through contact with the puzzle author and puzzle type inventor they have confirmed that the constraint for that type...

Re: UKPA Open Sudoku and Puzzle Tournament 2024
Looks great! A tiny note: the names of the rounds for round 4 and round 5 of the Puzzle event are the wrong way around on the schedule.

Re: 2024 UKPA Open Sudoku and Puzzle Tournament
Just to note, to add to Alex's incredibly helpful list of hotels, that the prices are for someone staying for 2 nights - but it is the Saturday night that is more expensive so if you are only doing the sudoku and so stay only on Friday night it is currently £48.50 at the nearby Premier Inn, as oppos...

Re: Upcoming international puzzle and sudoku events
Liane, the UK events have been on there since the first version. The dates are in US format and it is sorted by the order they were added to the spreadsheet, not date order. You must not have scrolled down far enough. We can volunteer dates on the relevant Discord channel, which I did a few weeks ag...

Re: Division D 2021-22
The instructions are slightly wrong, or at least incomplete. Where they say "cells with numbers" they should say "grey-shaded cells", given that there are some that have no numbers. This might be obvious in practice but it is nonetheless important because otherwise you might naiv...

Re: A Gogen Puzzle I Created Myself
I can't see why they would be hard to computer generate anyway, and the newspaper ones presumably are. Its easy to make a random solution grid and then you just need a simple brute force solver to allow you to remove given letters to the limit of uniqueness, or test for uniqueness with a fixed given...

Re: Scrabble type puzzles
Thanks Tom. In which case, would you personally be happy with "not even at a corner" as a replacement for "not even diagonally"? As in "Shaded areas cannot touch, not even at a corner?" I agree that more technical language such as referring to cells, edges and so on has...

Re: Scrabble type puzzles
“Not even diagonally” is definitely top of my hit list But what is brief, equally clear and unambiguously translatable language that completely avoids mathematical concepts such as "edge", "vertex", "orthogonally" and so forth - so is suitable for a general, internatio...

Re: Thermo miracle methods
If you want people to help you'll need to explain the rules, since this clearly isn't just a regular thermometer sudoku.
I tried googling your link but it didn't bring up the video with the rules, and 'Thermo miracle' brought up a different cracking the cryptic puzzle.

Re: Four Winds
@Gareth: Not necessarily. IMHO if a cell remains empty, it is not reachable at all. Or can you post a contra-example (which has only one solution)? The following puzzle has only one solution, and yet the square marked 'x' is reachable but not visited in the solution. It also has a second square not...

Re: Printing puzzles for contests
It's a good question. Until recently it had never occurred to me that people would solve on screen during a competition, because to me it seems self-evident that this gives a potentially big advantage for certain puzzle types. Even though on-screen solving may be a disadvantage in some cases, e.g. i...

Re: Four Winds
The two main things that I will look for is cells which can only join to one given number, and numbers which only have so many possible cells that they can join. It should probably be noted that the first rule only applies if the sum of the numbers is equal to the number of empty squares, which is ...
