Remove the mahjong tiles pair by pair until all the mahjong's are gone. You can match a mahjong only if it is not blocked from both sides and that it does not have any other tiles stacked above it. When you finish a set, you will be promoted to the next level. There are a total of 3 levels. The faster you finish a level, the higher the score you get. Remove tiles by matching them in pairs. You can only match tile that are not blocked by other tiles from the left, right or top. Have fun!
