Tap on two identical mahjong tiles to clear them from the board. Search for tiles that are not covered on at least either the left or right to choose them. Match the same tiles to eliminate them and uncover more tiles. Clear each level by removing all tiles from the board. Advance to the next level once the current one is completed. Employ the assistance feature if you're stuck. Think your moves carefully as some tiles may block others from being picked. Watch the timer in timed levels to guarantee you finish the level before time runs out.
