How to play

Colour every square of the grid black or teal. A numbered square tells you how many teal squares it can see in a straight line up, down, left and right, counting itself, and the small figure beside it tracks how many are still missing. Teal squares must all join into a single connected region, black squares can never touch, and a square turns red the moment a placement makes the grid unsolvable. 3 reveals are there if you stall.
