Value
mahjchina Taiwan profile: a base win is 2 tai, concealed-triplet awards can stack, and All Triplets is 10 tai. Agree on the table’s tai schedule before using these values elsewhere. Rule choices & sources →
- A normal win has 17 tiles: five sets and a pair; seven pairs plus a pung also qualifies. Base win is 2 tai. Each flower gives 1 tai; no flowers gives 1. Concealed self-draw gives 3 instead of separate 1+1 awards.
- This profile accumulates the two/three/four/five concealed-pung thresholds. No Honors/Flowers stacks with No Honors. Pure Straight is 5, or 10 when all three used chows count as concealed. Other Taiwanese house tables may differ.
- Discard: one payer; self-draw: all three. When winner or discarder is dealer, add 1 dealer tai plus 2 per previous dealer win. Otherwise add none. Seven-flower robbery pays 20 from the eighth-flower holder; eight flowers pays 30 from each opponent, without dealer bonuses.
