Split mode When playing this mode, the goal of the game is to make sure that one side of the field contains all the black balls, while all the white balls are on the other side. This will result in the background colours being purely black and purely white. Achieve (and maintain) this within the time, and you win. Mixed mode When playing this mode, the goal of the game is to make sure that both sides of the field contain equal amounts of black and white balls - this will result in the background colours being the exact same shade of grey. Achieve (and maintain) this within the time, and you win.
