Very fun test, with some really good puzzles. Nice sudoku, excellent suramoru, ripple effect and LIT(s), amongst others.

I made some stupid tactical choices, like wasting the last 10' on the Hashi, a puzzle I dislike, instead of solving the Numberlink and checking my Fillomino on which I was almost sure of having done something bad - and indeed, I had. But all in all, a satisfying performance for me.

Thanks Tom, and big congrats to Hideaki for such an impressive performance.

I agree, very fun puzzles. During the contest I had to rely a little bit on intuition on some puzzles (the Yajilin which I've solved properly afterwards, the Fillomino where I should probably have summed up the clues at some point, and also the Nurikabe. I still need to revisit that one.

Just now I looked at the marathon Heyawake, and was wondering if anyone else is having trouble with uniqueness? I solved it properly until just a patch in the bottom right and the top right are not filled in. Aside from room 'B' which is still open, my solution agrees with the correct code. It looks like the bottom right should close up so that connectivity forces a path along the right edge, forcing the top right including B=1, but I think I have a valid solution with B=2…

Most likely I'm missing some wrong room count or three-room violation, but I really can't find any at the moment. (A uniqueness argument forces B=1, so there's a very small chance an ambiguity would have been missed in the tournament.)

Here we go - not quite in Hideaki's time, but I did have to faff around uploading and stuff!

Thanks, that helped! A 4-room some distance away had just three black cells… I'll give it a fresh try tomorrow.
