How to play: Color flood
The controls
Choose one of six colors. Your whole region changes color and absorbs adjacent matching cells. Symbols and numbers distinguish colors without relying on color vision alone.
A little strategy
Look for a color that opens several boundaries at once. There is no move limit: first finish the board, then try using fewer turns. Undo lets you try another approach.
Can I run out of moves?
No. Keep playing until the board is complete. The counter records your choices; there are no lives, countdown or arbitrary move limit.
