Mahjong Sage
Hong Kong rules, fan scorer
Only for iPhone
Free
iPhone
A free companion for the Mahjong table. Look up a rule, score a winning hand from the tiles you tap in, and track the session. Hong Kong rules and fan values.
Mahjong Sage is 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 FIRST
Mahjong Sage speaks the Hong Kong ruleset, with house rules you can set to match whatever your table has always done.
Great for:
• New players who freeze on setup, direction of play, or "did I win?"
• Mixed tables where everyone learned slightly different rules
• Travelers and expats bridging the rules they know to the ones on the table
• Ending the argument about what a hand is worth, without a phone search
• Keeping score without a pencil and a napkin
What you get:
• Searchable rules reference and a full fan card of scoring patterns
• Winning-hand auto-scorer with an itemized fan breakdown and the payout
• Round setup — seating, initial dealer, prevailing and seat winds
• A live direction-of-play diagram
• Four-player session tracking, per-hand logging, and end-of-session settle-up
• House rules you can bend to match your table
• Works offline — no account, no login, nothing uploaded
Free to download — no subscription, no account.
