The conveyor belt is set, and the guns are on standby. Tap to launch the cannon onto the conveyor — it will rain balls onto the pixel cubes of the matching colour. The number above the cannon indicates how many shots it has left. When the ammo runs out, the cannon will exit the stage; otherwise, it will move to one of the five reserve slots and, with another tap, return to the conveyor to fire again.
玩法说明
Tap the cannon to place it on the conveyor. The cannon fires only at pixels of a matching color. Make sure you have enough free slots for cannons, otherwise, it’s game over.
