Mahjong Sage
The referee for your real-table game.
A free companion for Mahjong played with actual tiles. It settles the four things that stall a real table: how to start the round, which way play goes, whether that hand won and for how much, and what the rules actually say.
What it isn't
Mahjong Sage doesn't play Mahjong. There's no AI opponent, no online table, no tiles on the screen to tap. The tiles stay where they belong, on the table, in front of you. The app is the referee, the teacher, and the scorekeeper sitting beside them.
Three tabs
Learn is a searchable rules reference plus a fan card that lists every scoring pattern, so nobody has to take the loudest player's word for it.
Score is the auto-scorer. Enter a winning hand and the context around it, and you get an itemized breakdown, which patterns it hit, what each is worth, and who pays what.
Track runs the session: seating and the initial dealer, a live diagram of which way play passes, running totals for all four players, every hand logged as it happens, and a settle-up at the end.
Hong Kong rules, your table's house rules
Mahjong Sage speaks the Hong Kong ruleset, with house rules you can set to match whatever your table has always done, minimum fan, the limit cap, how the counting curve climbs, who pays on a discard, and what the base fan is worth.
