tricky but it's solvable with logic alone

Very cool puzzle, Ant. The challenge was just enough to make it fun, and the image is good too. Thanks for making your puzzles small and solvable. :-)

Very cute. A fun solve with a rewarding image.

ditto #3 and 4

Excellent puzzle!

This is a fun puzzle, but is it mis-marked? I got rows 1-5 and 18-20 done, along with most of the edges. But I combed through the middle rows/columns and couldn't find anything.

So I'd like to see if this should be reclassified, but I'd also like to share a neat puzzle people may've missed.

My solution: I used edge logic on the 4 in row 15 once the line logic dried up. There was slight lookahead to get the necessary contradictions before line logic finished the job.

After basic LL (The purple arrow hints)

r12c11 & 13 white (because r12c12 must be a 1 in that row)

purple logic to finish

If a puzzle is marked line & color logic, it is guaranteed to be so. The create solver is extremely competent. It also will not mark something as solvable unless it has solved it

I agree - line and color logic. There were places where I had to pore over the puzzle to find a single pixel in order to move forward, but it was all do-able.

I'd love to watch a visualization the create-solver work at 1/10000000th speed. I imagine it'd be like watching a windows 95/98 computer defrag.

Adorable. I couldn't find my way through, so I took a guess on one move and checked. That was enough to finish without any more help for me.

Yonah - I like that! I'll add that to the To Do list for someday.
