Keep score beta
Mahjong Almanac 麻雀通勝
A live scoreboard for a real table. One person records each hand on their phone; everyone else follows from a share link. Every session survives as a record you can go back through.
Start a session West 西 Peter −24
North 北 Anissa +16
南 hand 5
South 南 Nancy −40
East 東 莊 dealer Augie +48
How it works: start a session, share the QR or link, record each hand as it's won.
Scores, dealer, and prevailing wind track automatically; every entry can be voided
or reopened, never silently edited. No accounts — the share code is the session.
Research beta
Start a research session Start a research session. Tags every win with its hand type, and adds win-condition frequencies and a fan × hand-type breakdown to the stats. Slower to record — you answer an extra question each hand.
