Japanese Modern: Overview Gameplay Scoring Penalties & Errors Resources

A minimum of one yaku is needed to call for mahjong. After winning add up all the minipoints (fu) and yaku/fan then convert the values using the charts below.

Initial Points

If you are playing casually everyone can start arbitrarily with 25000 points.


A minimum of one yaku is needed before going out. You cannot be furiten when going out. The dealer usually pays more upon losing but on the same token receives more when winning.

  • Win by a discarded tile: Discarder pays winner full score plus values for other players as well.
  • Win by self-drawn tile: All player's pay the value of the winner's hand.

Optional Rules

The following are optional rules regarding criteria to being able to win and other scoring adjustments.

Two Fan Minimum ryanhan shibari (二飜縛り) - When there are five counters out (due to Dealer's consecutive wins or draws) a minimum of two yaku are needed to go out. Dora and red five tiles do not count towards the yaku minimum.
Double Ron - Allowing two players to win on a discard. The discarder pays the full score of both players. Riichi bets go to the next closest player to the discarder. Players who declared riichi are privileged to the ura dora and kan ura dora bonus.
Triple Ron - Allowing three players to win on a discard. (This would normally be considered an abortive hand).
Wareme (割れ目) - The player whose wall is broken at the beginning of a hand scores double if he wins.
Agari Yame - If the dealer wins the final hand and is in first place he may choose to end the game early or to play an extra hand.
8 consecutive deals(八本場) - When the dealer counter becomes 8, the dealer can win on any valid hand and counted yakuman.


Upon scoring, if you have less than five fan in your hand you must add up any fu and follow the values based on the charts below. The minipoints (fu) are then rounded up to the nearest multiple of 10. If you have five or more fan you do not add up any fu directly use the limit hands chart below.

Scoring Table

All patterns below qualify as a yaku and show their fan value. Players who score a yakuman or double yakuman do not count any additional fan. Note that the following is a comprehensive list of yaku, some of which may not be recognize by all players. It should be agreed upon which yaku can be counted before playing.

Example 1

Consider the following example. East (東) round; South (南) position; Dora: b6.gif. Ura-Dora: d8.gif.

b6.gifb6.gif c1.gifc2.gifc3.gifc4.gifc5.gifc6.gifc7.gifc8.gif d1.gifd1.gifd1.gif c9.gif

Dora (x2) 2 fan
Fully Concealed (menzen tsumo) 1 fan
Full Straight (itsuu) 2 fan
5 fan
Payment 2000/4000

Since the value is 5 fan we can skip counting the minipoints (fu) and go directly to the limit hands table. A self-drawn 5 fan hand (mangan) receives 4000 from the dealer and 2000 from each non-dealer (total of 8000).
