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: UKPA Monday evening Zoom drop-ins

Thursdays are busy in general for me so I'll have to give it a miss if so.

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...

There's also this puzzle of mine where I think the X-Wing is quite clear, if you'll forgive the superlative introduction to the video: https://youtu.be/gVT786t1Kjk?t=165

Re: Classic sudoku speed

By putting them in rows/columns that are largely filled, typically. I think I did an okay job of it on puzzle 2 of round 2, last year.

Re: UKPA Masyu Contest 14 May - 19 May 2021

Thanks David! The puzzles were fantastic :) I failed to check my printer beforehand and after finally convincing it to join my home network I found that it was actually out of ink (!), so I ended up solving under less-than-ideal circumstances. I really struggled with counting the answer keys on my s...

Thank you for the contest, David! I was beset by printer issues but was able to take part anyway using good old Snipping Tool. Always a pleasure to solve your puzzles.

Re: UKPA Masyu Contest 14 May - 17 May 2021

Thanks, David! Can I confirm that the constraint in No Touch Masyu is only on orthogonally adjacent cells? When I see the phrase "No Touch" in other contexts (for example No Touch Sudoku) it brings to mind a constraint that also includes diagonal touching, so just making sure that isn't the case here.
