Add the numbers to make perfect 9s!
Swipe to move the tiles. When two tiles merge, the numbers are added. When the value of a tile is 9 it pops and you score a point.
Careful though! When the value of a tile is more than 9 it will lock, and the only way to unlock the tile is to pop 9s next to it.
Score bonus points by making chain reactions and popping multiple tiles at once, and reach a high score!
