Each number counts the black cells its arrow points at. But number cells can be shaded too, and a shaded number no longer counts. Decide which numbers to keep, and the black cells follow.
What makes it fun
You can shade the numbers themselves
A number that does not fit can be painted over and ignored.
You choose which numbers to trust
Keeping or shading one changes how the others read.
Every arrow you keep fits
Once solved, each number left matches the black cells it points at.
Every puzzle here has one answer, and you can reach every cell of it by reasoning.
