MAHJ Formats
Fresh ways to rehearse American Mahjong
Original, fair, teaching-first formats for every table — curated rehearsal environments, not official-card duplication.
MAHJ Formats
Bring your card, host a table, review your hands, and play beautifully.
Original rehearsal formats for every table — separate from your printed card.
BYOC separation
Use BYOC when you want real-world card familiarity beside your printed card. Use MAHJ Formats when you want fresh, original rehearsal environments — both coexist; neither displaces annual-card players.

Fairness doctrine
- Does not displace your printed card — annual-card authority stays at home
- No league points tally or line validation
- No purchased advantage — curated teaching only
- No random chaos — every format has learning goals and explicit non-goals
- Experimental formats are labeled clearly (e.g. Teaching Night)
