How it works
Mahjong Logbook is a free, no-sign-up score tracker for any style of mahjong — American included. Log a game and the leaderboard, trends and head-to-head build themselves.
Name it and it exists. No sign-up, no password.
The room code is the address. Paste it in the group chat once.
Anyone can log it, a game must balance to save, and everyone else has it at once.
Features
Pick the date, pick the players, put down what each one won or lost. A game that does not balance will not save, so the book always adds up. Any entry can be edited or deleted.
Who is up over all and who keeps paying for the table. Read the whole history, or filter to a year or a quarter.
One line per player, game after game. Form and slumps show up at a glance.
Counted only across games you shared a table. Who you beat, and who has your number, pair by pair.
No passwords, no sign-up. The link is the key.
Runs in the browser, the same on a phone as on a computer.
One person logs the game and the whole room has it. No screenshots going round.
A game must sum to zero before it saves, so errors cannot pile up.
Each device picks its own language without changing anyone else's.
Free for up to 10 players, no adverts. Upgrade when you outgrow it.
A record book for a mahjong group. You write down what each player won or lost over a game, and the leaderboard, trends and head-to-head are computed from that. Score hand by hand at the table, or enter the game's final totals afterwards; both work.
Free to start, with no adverts. A free room holds up to 10 players; beyond that, or for head-to-head analysis, upgrade that room to Pro at $12.99 a month, or $7.99 a month billed yearly. There are no accounts: start a room and share the link.
Only people with the link. The room code is the address, rooms are not listed anywhere, and search engines are kept out of them. Treat the link like a key.
Cantonese and HK style Taiwanese mahjong are built in, and each game is tagged so the records can be read apart. Any game where a session ends in a number per player can be written down.
Any game can be edited or deleted, and a game that does not sum to zero will not save in the first place.
In a shared cloud database, so a new phone changes nothing.
A game takes four players or more, since seats change hands along the way. More people and more tables record just the same.
Yes, two ways. A league that runs over weeks gets its own room: log each round as it finishes and the leaderboard is the live standings. A one-day event starts a tournament at mahjonglogbook.com/tournament (beta, in English or Chinese): pick a format, paste the roster, then seating, per-table entry and live standings follow.
Free, nothing to install, ready in half a minute.
