The object of the game is to change the colour of the squares until the entire screen is a single solid colour. This is done by using the coloured buttons on the bottom of the screen to change the colour of the square in the upper left hand corner and those surrounding it. Changing this square to the colour of those around it, allows it to slowly grow until it fills the entire screen. The ultimate goal is to clear the screen in as few moves as possible.
A one time in-app purchase is required in order to unlock additional game modes, color schemes, and app statistics. The full version of the game has two grid sizes for varying the strategy of play. Win/loss percentages are calculated for all difficulty types and grid sizes, as well as all time best scores, and a number of achievements.
