Envelope

How to play

1. Paint every piece red, yellow or blue.
2. Each colored dot in a piece means one of its neighbors is that color; two red dots mean at least two red neighbors, and so on. Neighbors share an edge; touching at a corner doesn’t count.
3. A wrong color is rejected and costs a heart. Correct pieces lock in.

Pick a color with the buttons or the keys R, Y and B, then click a piece. Some pieces hide their dots until you paint them. Counts beside the board show how many of each color are left to place.
