Scoring variations

Settling table – Mangan scoring

In the Mangan scoring system, used in modern Japanese Mah Jong, the scoring for patterns and other qualities of the hand is specified by assigning certain amount of basic points (fu) or doubling factors (han) to each scoring item.

Han factors behave much like doubles, though the doubling effect is decelerated as the amount of han increase. Player's final score is determined by looking from the settling table the amount of final points certain combination of fu and han earn. The basic points (fu) are rounded up to nearest ten to determine the fu row. The values of the settling table can be specified either as direct point values or as percentages of the Limit points. Many special hands may pay multiples of limit.

Notice that the final score determined by the settling table is not necessarily the same as the final payment points. E.g., final score is often doubled if the winner or loser is East (dealer). Usually the points are also rounded up to nearest hundred at the time of payment.

E.g., in the Japanese Modern rule preset, where the dealer (East) pays and receives double and the discarder pays for all losers, the actual rounded payment values are as follows (based on the settling table displayed above):

1) Dealer (East) goes out self-drawn, each loser pays double the final score determined by the settling table, rounded up to nearest hundred:

	1	2	3	4	5	6–7	8–10	11–12	13
20 fu	400	700	1300	2600	4000	6000	8000	12000	16000
30 fu	500	1000	2000	3900	4000	6000	8000	12000	16000
40 fu	700	1300	2600	4000	4000	6000	8000	12000	16000
50 fu	800	1600	3200	4000	4000	6000	8000	12000	16000
60 fu	1000	2000	3900	4000	4000	6000	8000	12000	16000
70 fu	1200	2300	4000	4000	4000	6000	8000	12000	16000
80 fu	1300	2600	4000	4000	4000	6000	8000	12000	16000
90 fu	1500	2900	4000	4000	4000	6000	8000	12000	16000

2) Dealer (East) goes out on a discard, the discarding player pays for all (6 times the final score determined by the settling table because the winner is East and then rounded up to nearest hundred) :

	1	2	3	4	5	6–7	8–10	11–12	13
20 fu	1000	2000	3900	7700	12000	18000	24000	36000	48000
30 fu	1500	2900	5800	11600	12000	18000	24000	36000	48000
40 fu	2000	3900	7700	12000	12000	18000	24000	36000	48000
50 fu	2400	4800	9600	12000	12000	18000	24000	36000	48000
60 fu	2900	5800	11600	12000	12000	18000	24000	36000	48000
70 fu	3400	6800	12000	12000	12000	18000	24000	36000	48000
80 fu	3900	7700	12000	12000	12000	18000	24000	36000	48000
90 fu	4400	8700	12000	12000	12000	18000	24000	36000	48000

3) Non-dealer goes out self-drawn, dealer pays double (as specified in table 1) , other losers normally (the final score determined by the settling table, rounded up to nearest hundred) :

	1	2	3	4	5	6–7	8–10	11–12	13
20 fu	200	400	700	1300	2000	3000	4000	6000	8000
30 fu	300	500	1000	2000	2000	3000	4000	6000	8000
40 fu	400	700	1300	2000	2000	3000	4000	6000	8000
50 fu	400	800	1600	2000	2000	3000	4000	6000	8000
60 fu	500	1000	2000	2000	2000	3000	4000	6000	8000
70 fu	600	1200	2000	2000	2000	3000	4000	6000	8000
80 fu	700	1300	2000	2000	2000	3000	4000	6000	8000
90 fu	800	1500	2000	2000	2000	3000	4000	6000	8000

4) Non-dealer goes out on a discarded tile, the discarding player pays for all (four times the final score determined by the settling table) :

	1	2	3	4	5	6–7	8–10	11–12	13
20 fu	700	1300	2600	5200	8000	12000	16000	24000	32000
