DON'T TOUCH ANY WHITE TILE. This is the main rule in this additive game. Is it easy? Everyone can handle it, but not everyone can handle it well. What about you? There are four modes in the game: -Classic mode, get 40 black tiles as soon as possible. -Arcade mode, try your best to tap the dark tiles as many as you can, and do not miss one. -Time mode, try your best to tap the black tiles as many as you can in 60 seconds. -Crazy mode, another Arcade mode with no upper speed limit.
