The game starts with a 10x13 field full of figures of different shapes and your goal is to remove them. If you see two or more figures of the same kind that reside next to each other (on X or Y axis) you can remove them by taping on any of them. There is no limitation of the number of figures to be removed with a single move, but you cannot remove a single figure.
When a block is removed, the above figures fall down and fill the gap and when a whole column is removed the columns next to it shift on left.
If you can predict how each move will affect the progress of the game you may win.
