Play, learn, and keep the score.
Hé Fēn brings together browser play, a rules and strategy library, and an app for scoring physical tiles. Choose a built-in version or bring a house-rules document. The aim is to spend more time enjoying the game and less time untangling the arithmetic.
Between games, look up a scoring example, compare variants, or follow a question into Hé Fēn Lab.
Which rules do the guides describe?
Each guide names a specific Hé Fēn ruleset. Taiwanese Classic uses tai scoring; Taiwanese Club follows the club house sheet. Hong Kong New Style, Japanese Riichi and Chinese Official MCR each have their own reference and strategy guide.
The guides explain the rules used in Hé Fēn, with examples to help you understand a hand’s score. Strategy guides explore your choices; the Lab tests specific ideas in simulated games.
Families and clubs often have their own variations. Check the guide against your table’s sheet and choose the available options that fit your game.
What is the Strategy Lab?
The Lab tests specific playing habits in simulated games. Its reports separate the question, the observed result and the limits of the comparison. An experiment can challenge a familiar rule of thumb without proving the best move in every hand.
A little character, a real game.
The sunlit manor and its cast bring a little escape to your game. Our illustrations are created with AI under our art direction. The app screenshots show the game itself.
