Any chow/chi always scores 0 points. (This is for mathematical reasons - there are about ten times as many chow/chi combinations possible, as pong and kong combinations.)

All other pairs score 0 points. Your own wind is defined as your seating position right then: South if you are sitting in South position, and so on.

An exposed pong is one containing a tile claimed from an opponent. A concealed pong is one where you yourself has drawn all the tiles from the Wall.

The following doubles apply ALL the players in Chinese classical mahjong, whether going out or not:

Note that some of the doubles exclude each other in a logical way: if you have two sets of Dragons and a pair of the third Dragon, the individual doubles for the two sets are already included in the 3 doubles. Note that all applicable doubles are cumulative, meaning that the points you score may for example be doubled three times over (2x2x2 is 8) where applicable.

The player going out by achieving mahjong may in addition to the Basic Points above also include the following additional points (before doubling), as applicable:

The only possible tile is defined as:

Note that "The only possible tile" refers to the one value needed to complete your mahjong hand. If you have 6 and 8 of Bamboos in hand and are waiting for the 7 of Bamboos and there are two or more such identical tiles remaining in the game, it does not matter which of these 7 of Bamboos tiles you draw or claim.

The player going out by achieving mahjong may in addition to any doubles listed above also apply the following doubles, where applicable:

Also all these doubles are cumulative, where applicable. In order to simplify the calculations, it is suggested that you after you have calculated the points then calculate the number of doubles, and do the math.

1 double - multiply by 2

2 doubles - multiply by 4

3 doubles - multiply by 8

4 doubles - multiply by 16

5 doubles - multiply by 32

Since a player's score, using many doubles, could theoretically run into millions of points when winning with a very unusual and lucky hand, a limit on the number of points a player can score is applied. This limit is usually between 200 and 2000 and is set for each table in the MahjongLogic game. (This limit applies regardless of whether you are playing East or any other position.)

Note that you may also go out with any of a number of special mahjong hands, which do not necessarily confirm to the "four sets, one pair" rule above! See the Special Hands section for a list of these special hands, which are all limit hands as they score the maximum number of points allowed in the game.

Once a player goes out, he or she scores his hand first, and receives that number of points from each of the other players.

Then, in Chinese classical mahjong, the other players in counterclockwise order score their hands and receive that number of points from the others but NOT from the player who went out.

In a live game, the score is kept using tally sticks or chips even poker chips will do nicely or sometimes using just paper and pencil. When playing at this site, naturally all the scoring is done automatically by the software and shown on the screen.

West went out, with a mahjong hand made up of the following combinations:

That gives a sum of 52 points.

In addition, the player receives a double for having a kong in his own Wind.

That gives a final sum of 104 points.

East, South and North now all pay 104 points each to the winner West. If all players started with 2000 points each, the score for the moment looks like this:

East: 1896 p. South: 1896 p. West: 2312 p. North: 1896 p.

(Note that mahjong is a zero-sum game: what one player wins, another loses. If all players started with 2000 points each, the sum total of all four players' scores must always total 8000 if all the calculations have been done correctly.)

West has finished scoring; now it is North's turn. She has a concealed pong in White Dragons in hand (8 points), an exposed pong in Simples (2 points) and one Season tile (4 points, but it is not her own). Her uncomplete hand is therefore only worth 14 basic points, but in addition she receives a double for her pong of Dragons, bringing the total up to 28 points. She receives this amount from East and South (but not West, since he won the hand), after which the score for the moment looks like this:

East: 1868 p. South: 1868 p. West: 2312 p. North: 1952 p.

East has two chows (0 points each), one pair in East Wind (which happens to be his own wind, so 2 points), an exposed kong in 8 of Dots (8 points), but otherwise worthless tiles. Sum total is 10 points, which he receives from South and North respectively.

South, finally, has a concealed pong in 1 of Bamboos (8 points), an exposed kong in West Wind (16 points), a Season tile (4 points), a Flower tile (4 points, and it is his own Flower), and a pair of Green Dragons (2 points). The sum is 34 points, which the double for his own flower brings up to 68 points. After scoring this as well, the final point standings after the hand are as follows:

East: 1820 p. South: 1994 p. West: 2312 p. North: 1874 p.

... and once again, the total of all players' points after this hand is 8000 in this example.

Note that it is actually possibly for a losing player to score more points than the winning player who went out, if the winning player has a very low-scoring hand but the other player has almost completed an exceptionally strong hand!
