Mahjongg - Spielregeln in Kurzform
In the game of Mahjong, 144 tiles have to be cleared from the board. In order to achieve this, 2 equal tiles have to be clicked consecutively. One thing to watch out for is that the tiles one wants to clear are not blocked by other tiles.
There is only one level in each game. Once one player has managed to clear all tiles from the board, the game is over.
The game can also be ended manually or if time expires. If you clear several consecutive pairs of tiles with the Circle symbol, you get 20 points for the first pair, 30 for the second, 40 for the third and 60 for the fourth. 25 points are deducted for clicking Undo, as are the points for the move which was reversed. 100 points are deducted for clicking "Shuffle". You get 500 bonus points for clearing the entire board.
