Tiles fill the board up and you have to remove them before the tiles reach the top or the game is over.
Remove a row of tiles by selecting tiles on the right that match tiles on the left. Clicking on tiles that do not match locks the entire row and you will not be able to remove the row. You get bonus points with less row of tiles on the board. Choose mahjong, jewels, playing cards, or hieroglyphics style. Full version has unlimited levels.
