Fill each of the piece of the puzzle with one of the 4 available colours. Do not let pieces of the same colour touch (share a side). Try and use as few colours as possible when solving a level. Many of them can be completed in 3 or less. (Check the level select menu to see which ones you have left.)
Use the mouse and the 1, 2, 3, 4 or A, S, D, F keys to switch colours.
