Re: UKPA Yajilin Contest (10 Sep - 13 Sep)

I also want to say thanks to everyone who took part. I know there are a number of solvers who were taken aback by the difficulty. I considered applying a warning to the contest beforehand, but I didn't want to 1) scare off people who might have otherwise enjoyed it or 2) influence how the top solver...

Re: UKPA Yajilin Contest (10 Sep - 13 Sep)

Hi pin7guin, Here are some examples of the rule in action which hopefully will clear things up. This situation is not allowed , as the two squares are the same size (both 1x1) and can directly see each other https://i.ibb.co/G3mQxF0/disallowed1.png This situation is allowed , as although the two squ...

Re: UKPA Yajilin Contest (10 Sep - 13 Sep)

Sam, In the rules for Look-Air Yajilin, "the total number of distinct squares" is possibly open to misinterpretation. I briefly wondered if it meant "the number of distinct square sizes" e.g. the intended rule is that two single-celled black squares separated by a 4-cell black s...

Haha, well spotted. I did read over everything to check that I hadn't left in anything that didn't make sense or wasn't true but I missed that one.

Re: 2021 WPF Sudoku and Puzzle GPs

I did the same for Meandering Wordsearch and the 2 minutes I spent doing so was easily offset by how much easier the puzzle became to solve.

Re: UK Puzzle Championship 2021

Is there any chance of having the two sets of clues in Hashi/Hotaru Beam being a different shade? I think it would then be easier to tell them apart at first glance, rather than relying on the presence or otherwise of black dots.

Re: UK Sudoku Championship 2021

1 and 9 are not considered consecutive. The middle box actually contains four distinct shaded groups of two cells each, although I can see how it could be easily misconstrued :) In the contest puzzle itself the regions are clearly distinct from each other, so this sort of mistake shouldn't happen th...

Re: 2021 WPF Sudoku and Puzzle GPs

The Little Killer didn't need anything quite so contrived - at the sticking point (or at least, what was the main sticking point for me) you can simply ask where 9 goes in column 9.

Re: Classic sudoku speed

And to avoid derailing the thread, here are my thoughts on speed in classic sudoku: There are basically two ways to improve, IMO. Solve lots (thousands) of easy puzzles, which will do two things. Firstly, it will improve your raw speed at the essential skills like being able to see which numbers are...
