Crab Cove : Pixel Puzzle

Crab Cove : Pixel Puzzle is a calm colour puzzle. Each level is a pixel-art picture, and you take it apart by sending coloured blocks onto the board to collect matching pixels.

The catch is that only pixels on the edge of the picture can be collected, so you need to plan which colour to send next instead of tapping at random. Later levels add frozen, hidden and locked pixels that take extra steps to clear.

The game page lists more than 200 levels. It suits short, low-pressure sessions on desktop or phone.
