Slide the tiles so that matching pairs collide or are next to each other. Touch the tile you would like to move then slide your finger or mouse in the direction you would like the tile to go. When you release your finger or mouse the tile will slide until it hits another tile or the edge of the play area. If it collides with a matching tile they will both be removed. Your goal is to rearrange the tiles to eliminate them all within the time limit. There are 50 levels for you to solve.
