Scoring System

Terminologies

A Concealed Set consists only of tiles that originated in a player's private hand. Includes Concealed Quadruplets.

A Revealed Set consists of one or more grabbed tiles.

A Fully Private Hand must not have any Revealed Sets prior to declaration of MahJong. Such a hand can contain Concealed Quadruplets, and can be obtained by grabbing a discard or robbing a kong.

The fan of a MahJong hand is calculated by adding all the points that apply, from the following scoring hands, up to a maximum of 12.

Scoring in MahJong Online

A [normal] winning pattern consists of 5 sets of normal tiles. One of the set must be a pair, the other 4 sets can be sequences, triplets, or quadruplets. You can also have any number (including 0) of flower tiles. Here is an example:

Unfortunately, the above hand is worth 0 Fan and since most of the players in MahJong Online set the minimun winning Fan to 2, you will not be able to win with this hand (ie, the MahJong button will not be highlighted)
The following section explains the various ways you can score in MahJong Online (from 1 Fan to 12 Fans). Please go through this section even if you are already a veteran MahJong Players in real life because the scoring system may be quite different here.

Counting the Final Score

Auxiliary Points

The auxiliary point is the sum of all points from applying the following rules to the Set(s) and Pair(s) in the hand.

Each revealed quadruplet: 1 points.
Each concealed quadruplet: 2 points.
If the use flower tiles option is on, each flower tile: 1 point.

Then, we adjust the fan value by:

if aux < 2, do nothing.
if 2 <= aux < 4, add 0.5 to fan.
if aux >= 4, add 1 to fan.
Fan should not to exceed 12.

Note:

Fans awarded from auxiliary points are just bonus and are not calculated unless you have win your hand.
Hence if you hand is worth 1 Fan with 4 auxiliary points, you will still not be able to win a Table that set the minimum winning Fan to 2.

Your Final Winning Score

Your final Fan is the Total Number of Fans from Your Winning Hand + Extra Fans from the auxiliary point.
Your score is then calculated from the following table:

Adjusted Fan 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6
Basic Score 2 3 4 6 8 12 16 24 32 48 64 70 75

Adjusted Fan 6.5 7 7.5 8 8.5 9 9.5 10 10.5 11 11.5 12
Basic Score 80 85 90 95 100 105 110 115 120 125 130 144

The hand's Total Score is a multiple of its basic score, the multiplier given by the following:

Non-dealer Dealer
Win on grab 1.0 1.5
Self-feed 1.5 1.5

Points are allotted from non-winning players to each of the Winners separately. Each Winner always receives his Total Score many points. In addition points will be deducted from non-winners and credited to winners according to the following rules, which are to be checked in the order given, i.e. the first applicable rule encountered is the one applied.

Winner made 4 chows: Winner made 4 chows in his/her Mahjong Hand: the player to winner's immediate left who "supplied" the 4 chows pays Winner's entire Total Score to the Winner, regardless of self-feeding or who the feeder is.
