The same color can not be used to fill in adjacent shapes, requiring the player to form a strategy in order to complete each screen. Each screen is treated as a separate game. Two modes of play are available. The basic mode is a timed challenge for a single player, the player is scored by the number of seconds they spend to complete each screen.

The player who cannot take their turn due to the placement of colors on the screen or the lack appropriate colors available to use loses.
