Tứ Sắc ("four colours") is a southern Vietnamese melding game played with a 112-card pack in four colours, related to Chinese Kanhoo and to the same broad family as Mahjong. Sets are built and scored with a detailed system of point values.
Status
Not implemented. This game appears in the catalog and is visible in the app,
but it is marked *Coming Soon* and cannot be played.
Pending: the melding and scoring system is intricate and deserves a dedicated implementation rather than an approximation.
We would rather show an honest placeholder than ship a rules approximation of a
game that people actually play.
