the winner's points, and the other players are off the hook. A discard is considered risky if there were enough open melds to reveal the fact that said discard is very likely to enable completing a limit hand before it was claimed. Note that some rulesets always make the discarder pay anyway. In this case, going out self-drawn after claiming a risky discard will trigger the penalty. The intent of these rules is to punish the player who foolishly enabled the completion of the limit hand.

Many variations may also impose penalties for discards that are considered to be "high-risk" when the size of the wall is winding down. If a player wins from a high-risk discard, or goes out self-drawn after claiming a high-risk discard, the player(s) who made the high-risk discard(s) have to pay for

Because of the large differences between the various scoring systems (especially for
Chinese variants), groups of players will often need to agree on particular scoring rules before a game to eliminate possible disputes during the game. As with the gameplay, many attempts have been made to create an

Points are obtained for a hand by matching it against various criteria, with different criteria scoring different values. Criteria can include particular melds or other tiles held, how the (winning) hand was completed, possession of various special combinations, etc. Some of these criteria may be

While the basic gameplay is more or less the same throughout mahjong, the most significant divergence between variations lies in the scoring systems. Like the gameplay, there is a generalized system of scoring, based on the method of winning and the winning hand, from which

If playing with chips, there is no universal rule for the situation when a player runs out. In some circles, the match is immediately aborted, with the player furthest ahead in score declared the winner, while in others, a player out of chips continues to play without risk of further losses.
218:
Each player begins the game with the same score. When settling up, in many cases only the winner is paid with the winner's gain being deducted from the three losers' scores (that is, the losers pay the winner). However, payment between players can be arranged in other ways. A common set of

A side effect of the
Babcock scoring system in the 1920s was that many players frequently sought after limit hands rather than hands of smaller value. Because of this, the common hands were eventually abandoned, and the only way one could win was to match a hand from a list of hands.
437:
Some variations may impose a scoring limit - a maximum to the number of points for a given hand. In many cases where limits exist, there may be either multiple limits, or ways to obtain multiples of a limit. In many cases where limits exist, the typical point translation function is
445:
A scoring limit may be more of a gambling incentive: for example, if six and nine points were scoring limits, a seven- or eight-point hand would be worth the same as a six-point hand, which may be an incentive for players to go for nine-point hands.

Singaporean scoring is similar to that of the
Chinese Classical system but accounts for the different set of tiles used therein. Again, standard payment variations apply, although variants exist where the dealer must also pay and receive double.

Today, in the
American variations, players use a card that defines a small set of hands that are the only valid winning hands, with a point value given for each hand. This system is used by the two major governing bodies of Mahjong in the

Typically, each card contains scoring criteria that make references to the year the scoring cards are released. For example, the 1985 scoring hand will have hands containing "melds" of a one, nine, eight, and five of a certain suit.

The general scoring modifiers apply (see above), with the point translation function being a piecewise function: a constant amount is given for scoreless hands, and the score is doubled for each point (that is, an

The winner collects their total points from each of the three losers. The losers pay each other the difference in their points. East pays or receives double amounts in their transactions.

In the case where a player wins from a high-risk scenario (see below), the player who performs the discard pays for the other two losing players (in addition to the normal double share).

300:
each player doubles their basic points one or more times based on possession of certain rarer melds or combinations of melds (for example a set of the prevailing wind tiles)

In contrast, the scoring system used in the
Shanghai variant is high due to the diverse number of scoring criteria and inflated values for rarer hands such as the
