For those of us who solve via the flood tool, could you replace the #FFFFFF pixels along the dotted lines with #FEFEFE pixels? Or do what Grant does with the gray jagged edges, perhaps?

Thanks for the comment. I’m still building all my render tools but had forgotten that feature. Refresh the page and you’ll see what should work, and I’ll keep that formatting for later puzzles this week.

• Jonah says:

Perfect. Thanks!

A fun easy fillomino.

• Carl says:

How do you solve it with the “flood tool”? What software are you using?

• Scott Handelman says:

I imagine he’s using a paint-like program to fill cells with different numbers different colors instead of filling in digits. Personally, I find it tedious to do this with any more than 2 colors (3 at the most), but I definitely tackle Nurikabe, Corral, etc. this way.
