2:05. The 10-square region on the right gave me some pause! If not for that one little bit I would have beaten Grandmaster. Ah, well. Nice puzzle.

• That 10-square region was the last one I filled in; in my case, I could see intuitively what shape would fit in there to complete the puzzle, but my puzzle-solving neuroses made me spend time actually proving that it was the only possible solution.

That part definitely stood out strongly in my solve too. Just as some Fillomino puzzles are memorable for how a large section breaks into hidden polyominoes just one way, that that 10 cell block has just one option was interesting to prove.

1:42 here, thanks for the heads up on the 10-cell region. No other comments.

• chaotic_iak says:

01:18 whee. Also the same 10-square region problem :O Although it’s not terrible (5-10 seconds).

Nice, smooth solve. If it’s not for the fact that it’s also a valid Double Back puzzle (or any other kind of puzzle), I would have commented on the lack of aesthetics, but well. So I’ll just give the Foxger the challenge of making a double puzzle like this while maintaining some kind of aesthetic theme 😛
