I am no longer using this account. For now, I'm on Bluesky: https://t.co/sZJHfoydLp
I may set up a puzzle-focused account there in the future.

I also have my site: https://t.co/wTWCdLOLNC
Later, I might also set up an RSS feed of site updates, which should include puzzles.

I'm not dead! But I haven't been writing puzzles much either. My old blog is dead, this Twitter is kind of dying (or at the very least, very inactive).

I'm working on porting all my puzzles to my website though: https://t.co/BRkoZEeBVR

If two regions are *not adjacent* (instead of adjacent), they must have different sizes. Otherwise Fillomino rules apply.
