Initial Points
Blood and/or Japanese yen are commonly used as wagers with a conversion rate of 100 ccs of blood equaling 1,000 points.
Criteria
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.
Outline
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.

Example
Example 1
Consider the following example. East (東) round; South (南) position; Dora: . Ura-Dora: .
|
 |
 |
|
| pair | waiting on 3-6-9 | concealed pung | self-drawn |
| 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).
