Let's play sum tracks - brand new, simple, easy to play, but very addictive puzzle game. The rule is simple - each time you swipe square tiles through round tiles the number in square tile is subtract to number in rounds tile. Move tiles until all round tiles is be cleared and all square tile numbers equal zero.
It's not easy as the descriptions above.The higher levels you get to, the more difficult they are. Don't let them take you down so easy.
Sum Tracks has 90 levels and is updating...
Let's swipe and fight against tiles!
