Re: Sudoku duel

I've also been having fun with this, I think it has huge potential. Regarding the interface, I'd prefer to not have to click twice, i.e., button down, move to number, button up. That would also make it easier to abort by releasing anywhere else, which is tricky currently. As to number of players, I ...

Re: LMI Puzzle Marathon

Haha, Deb just showed me a link where someone had gone off on one about kakuro in general, and how my puzzle magnified everything he hated about the puzzle. Anyhow - here are some thoughts: - Generally there is only one break-in when I put together something as big as this. This tends to be towards...

Re: 2011 UK Puzzle Championship (25-26 June 2011)

I still don't see a good argument for deducing that it's 444433 ....3. ....3. ....3. and not something else,...

Re: 2011 UK Puzzle Championship (25-26 June 2011)

Re: 2011 UK Sudoku Championship (11-12 June 2011)

Thanks for the contest. Quite a few nice puzzles here. I particularly enjoyed the top-heavy sudoku. The frameless sudoku was also great. I found the small consecutive sudoku quite hard -- thankfully I gave up quickly enough during the contest. I still haven't solved the Futoshiki and the no3-consecu...

Re: 2011 UK Sudoku Championship (11-12 June 2011)

I'm getting SQL errors when submitting the form. Is this happening to anyone else?

Edit: Looks like the submissions still got through. Thanks for the test!
