Your objective is to fill the entire grid with the same colour. To do this, select a colour from the palette on the right. The top left square and all squares connected to it will be changed to that color. Two squares are connected if they are adjacent and of the same colour.
Can you fill the entire grid in less steps than the computer?
The computer's number of moves is shown on top as (n/m) where n is the number of moves you have taken, and m is the number of moves to beat.
Enjoy!
