Where it comes from

Nonograms, invented in Japan at the end of the eighties and now in every puzzle magazine: numbers down the side, a picture inside. The good ones never need a guess, and that is a property you have to build in on purpose — so every grid here was checked for it.

How to play

What makes this one different

The numbers at the edge are enough: every grid has one answer and you can always reason your way to it, so no grid here needs a guess. Drag to fill a whole run in one gesture rather than eight taps, and use the cross to mark the squares you know are empty — those are your notes, not part of the answer.

On a big grid the crosses are what you are actually reasoning with: a square you have proved empty rules out as much as a square you have filled, and skipping them is why a puzzle that should take ten minutes takes an hour. They are notes and cost nothing — the restart button clears the grid and leaves the picture alone.
