Multiplier Rules in Mahjong, Part I

Multiplier rules are extremely common in regional mahjong. They usually leave the basic four-melds-and-a-pair structure untouched, yet can multiply a hand's value many times over. That is why they are exciting, and why they can also strengthen the gambling character of a game.

Kongs

A kong is a set of four identical tiles. Guizhou's *dou*, and Wuhan's single-wildcard or red-dragon kong, develop it into a separate scoring event. Some rules double an exposed kong and settle it immediately; Sichuan mahjong may count kong payments independently. These ideas retain something of the classical system of fu and tile roots. Chinese Official Mahjong, Zung Jung, and Japanese mahjong generally do not make a kong itself a separate payment item.

Kong multipliers affect hand-building choices: a player may keep a kong instead of pursuing a sequence or a one-suit route. Chinese Official Mahjong's refusal to double for dealer, self-draw, or kong is one way of excluding these chance-based increases from its primary scoring system. Many northeastern rules instead retain extra awards such as Whirlwind Kong, Joy Kong, terminal kongs, and "eggs."

Flowers

Flowers may be dealt to players as fixed holdings or mixed into the wall for random draws. They are often treated as independent points or multipliers. Chinese Official Mahjong gives eight points per flower; Nanjing mahjong values them more highly, and Wuhan mahjong can also multiply for red dragons and wildcard kongs. Obtaining flowers depends almost entirely on chance, so high flower values make random events outside the hand structure matter greatly.

Bonus tiles

A bonus tile is a designated scoring tile. It may be a fixed red bonus tile or be determined by an indicator. Unlike flowers, it remains in the hand and, when known, affects attack and defense. Nanchang's upper and lower *jing* tiles and northeastern variants called *bao* are examples. Japanese ura-dora are revealed only after riichi, while Changchun bonus tiles can be revealed after tenpai; both add further randomness to the result.

Birds and horses

Bird rules reveal tiles from the wall after a win and use their ranks to identify players whose result is doubled. Horse rules have a similar structure: a tile identifies a player, and that player's gain or loss is multiplied. In both cases, a random event after the hand has already ended can change the payment.

Conclusion

Kongs, flowers, bonus tiles, birds, and horses take different forms, but most increase the volatility of a reward. They can make a table livelier while making a result more dependent on a random reveal. The next article continues with dealer multipliers, side bets, carry-over multipliers, and similar rules.
