Re: UKPA Skyscrapers Contest 25 February - 2 March 2021

...it turns out the timer on the page was inaccurate and I ended up scrambling to put in my solution codes! Yes, it doesn't work properly. You need to refresh it regularly or use a separate timer. I sent Alan some replacement timer code when he first put the tournament engine online, years ago, but...

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 ...

Go to the contest page linked at the very top of the thread above, then click 'Open Page' to the right of 'Answer Submission Page'. Then click 'START NOW' to get the password. Your timer will begin at that point.

Re: UKPA Hybrid Sudoku Contest

That's a good point - and it's often particularly true for unusual puzzles. Instead of reusing an existing example, the author often won't have time to make the example work really cleanly. Not that I have even looked at the examples for this competition however - so I can't say if that applies here...

I never get Humble Bundle email about puzzle stuff either - only games I am not interested in. Seems they don't bother emailing out about that sort of thing.

Re: Important: UK Puzzle Championship competition booklet update

The competition is still open - the deadline was extended again from Wednesday to Thursday (i.e. one day more) due to problems with the web server hosting company.

To clarify, you have not (yet) missed it. You can take part until Thursday the 27th of June, so long as you start prior to 9:25pm BST.
