Re: Puzz.link

No, I'm not aware of any shortcuts. There are multiple online solvers being used, and multiple types of blogs/tweets to find them. Plus it's courteous to visit the author on the way, and often they share their thoughts on the puzzle. There used to be a lot of Japanese tweeters, and it took a little ...

Re: Results of 2023 UK Puzzle Championship

Thanks Liane for organizing this again, a nice mix of top quality puzzles from the authors. I did many many Japanese Sums in preparation.
Can't believe how close round 1 was, with the top 4 within 18 points of each other and 4 more within range - quite a shuffle once round 2 finished.

Re: Doppelblock

Nice idea Sam, thank you. Spotting that R5 and C5 must have the same length gap - I'll keep my eye open for things like this in the future. I also found a shortcut by using this in your first image: If R5 and C5 are both small gaps then you would have a 3 in R3C5 and also a 3 in R4C2, which breaks c...

Re: Doppelblock

Thanks for fixing that Adam.

In terms of learning, I'm curious about your solving thoughts for the second example.
After a quick start, I can find one digit and four blocks. Which way do you go next?

Thanks Tom, yet another close finish in a strong field. Even I felt disheartened at the end, I didn't look at 30% of the puzzles this time, which didn't seem good when I was hoping to finish, but not really a problem if there's too many to choose from. And the puzzles were very enjoyable, so my than...

Re: UK Puzzle Championship 2021

The example for 29 Jumping Crossword has an extra word: "HAZIR" which can't be seen in the solution.
Will the contest puzzle have extra words, or is this an error?

I've seen a few versions, under different names. There've been a few optimisers (how many of these words can you fit inside this grid), and it was in the WPC maybe 6 years ago.

Re: 2021 WPF Sudoku and Puzzle GPs

Yes. To elaborate: e.g. Look at the 32, 38, and 39 regions. They sum to 109, the whole puzzle sums to 136, so the left most pair of regions sum to 27. Now look at the 47. The left 2 are 27, so the right 2 are 20. This can continue along the lower edge. You'll find that the 50 and 37 sum to 30, so mu...

Re: Different Neighbours

Yes, obviously finding points where 4 cells meet help you propagate information quickly. Another thing that sometimes pops up is having a chain of cells where every 2nd cell must be a 4. If this chain loops back on itself then it must be even length, so you may be able to rule out options that would...
