Chinese Mahjong Scoring
Rules for scoring in mahjong are the following:
- Based on the presence of specific melds, pairings, and bonus tiles, each player adds up the fundamental points for his hand.
- Each player doubles his basic points one or more times based on ownership of specific uncommon melds or combinations of melds. The winner adds additional basic points for gaining mahjong and maybe for finishing his hand in several unique ways.
- Depending on his hand's formation of uncommon patterns, such as those made completely of honor tiles, or being finished uniquely, such as stealing an exposed kong, the winner doubles his basic points once or more.
- Each of the three losers pays the winner his entire points.
- The losers split the difference into points among themselves.
- In his dealings, East makes duplicate payments or receipts.
- There are many Special Limit hands that, if acquired, provide the possessor with the most points assigned to his hand.
American Scoring
In the American version, players utilize a card with a point value for each hand that specifies a narrow number of hands as the only legitimate winning hands. Two main Mahjong regulatory organizations in the United States, the National Mahjong League and the American Mahjong Association, employ this method, with new cards that specify the legal winning hands being produced every year. Each card often includes scoring requirements that make mention the year the scorecards are published.
Shanghai Scoring
The Shanghai variant's scoring system is complex, with a wide range of requirements and exaggerated ratings for more uncommon hands like the thirteen terminals. There is typically a minimum point value in the Shanghai variation due to the inflated point values.
Singaporean Scoring
While using a different set of tiles, Singaporean scoring is comparable to the Chinese scoring method. Here, regular payment variations apply. But, there are those in which the dealer is also required to pay and receive twice.
Hong Kong Scoring
Due to the limited number of factors employed in the conventional Hong Kong grading method, the score is frequently poor. The point translation function is a piecewise function, and the general scoring modifiers are in effect.
Scoreless hands are awarded a fixed sum, and each point doubles the score. Players sometimes play with the extra constraint that a winning hand must be of some point value, often ranging between one and five points, with three being the most frequent. This is because zero-point hands are common.
Japanese Scoring
Each player starts with a score. This amount is often between 25,000 and 30,000. It may be an agreed-upon initial value. In current tile settings, this is often represented by a row of bars with the following four denominations: 10,000, 5,000, 1,000, and 100. The bars resemble long Chinese dominoes. If not, all that is represented online are the point totals.
