Make as many combinations as possible within the wall of tiles by removing groups of identical ones. There are various layers of tiles, but you can combine them if they are adjacent. Tiles with nothing left underneath will fall down, and can make extra combos automatically. Combos created this way grant you bombs that you can use for single tiles. When you are out of moves, the cursor will switch to the bombs.
Use the mouse to click and remove groups of identical tiles from play.
