This is a perfect choice for all those who are fond of online Mahjong games. Beat the clock finding the identical stones that are free. Free stones are the ones that are on the edge of any of the layers of stones. You can click on the hit button to get help finding free stones if you do not see any. You have to find 5 pairs of stones per level, within the time given for that level. If you find 5 pairs the time is reset and the game continues. The available time gets shorter for every level and per level you will only get one hint.
