The family mahjong table by the window · 四人中国麻将
Click a tile once to lift it, again to discard. 点击麻将两次打出。
This is standard 4-player Chinese mahjong with 144 tiles (flowers included, auto-replaced). On your turn you draw one tile and discard one. Build a hand of four sets (runs like 三四五萬 or triplets) plus one pair. Special hands: Seven Pairs (七对), Thirteen Orphans (十三幺).
Scoring is fan-based: base 1 fan, +1 self-draw, +1 concealed hand, +2 all pungs, +4 full flush, +2 half flush, +4 seven pairs, +1 per dragon pung, +1 per flower, kongs, and more. Each fan doubles the payout (capped at 2⁸ = 256).
Turn lights on the table hub show whose turn it is; the red LED counter shows tiles left in the machine.
