About the game
Taiwanese Mahjong is the 16-tile game played at family tables across Taiwan. Each player holds 16 tiles and the dealer starts with 17. A winning hand is 17 tiles arranged as five sets and a pair, which makes hands longer to build and more varied than the 13-tile styles. All eight flowers are in play: they are laid out as soon as they are drawn, replaced from the back of the wall, and count toward the score.
Scoring is in tai with no minimum to win. A discard win is paid by the discarder alone; a self-drawn win is paid by all three. The dealer earns an extra tai, and every hand they keep the deal adds two more, the streak rule known as 連莊拉莊. The hand is declared a draw when 16 tiles remain in the wall.
What Seriauth built
The site runs the full rule set in the browser: robbing a kong, the pass rule on missed discards, dealer streaks and automatic tai counting with a complete breakdown on every win. Three computer levels range from a loose player who calls often to one that chases big hands and defends when you look ready. Four-player online tables offer quick matching and private rooms, with the computer filling empty seats. The game is drawn on a 3D table, can be installed as a PWA, and is backed by rule pages for the most-asked hands, from Ping Hu to Heavenly Hand.
