The original Mahjong game is an ancient one of patience and skill; reverse Mahjong is not. You have to rows of tiles, going in opposite directions. As they scroll by you must quickly click on a tile from the top row, and one from the bottom row in order to match them and remove them. This game has no end and keeps going on and on. Use your eyes to quickly spot matches and make them before it scrolls off the bored. You are racing against the clock in order to get the best time and beat everyone else's score.
