BamBoast

BamBoast is the elegant companion app for physical American Mah Jongg (NMJL rules) — the quiet co-pilot that sits beside your table and keeps the game moving. BamBoast doesn't play Mah Jongg for you. It doesn't deal tiles, simulate an opponent, or judge your hand. It just answers the three questions every table asks, one tap at a time. WHERE ARE WE? Follow the Charleston pass by pass — First Charleston, optional Second Charleston, and the Courtesy Pass — without losing your place. Every step is a single reversible tap: pink for pending, green for done. WHOSE TURN IS IT? Designate East and BamBoast tracks counterclockwise turn order automatically. Tap any seat at any time to correct course — no warnings, no friction. HOW AM I DOING? Declare Mahjong the instant you win. Every win counts toward your personal total, and you can optionally assign it to a generic numbered line on the current year's card (official hand patterns are copyrighted, so lines are tracked as Line 1, Line 2, etc. — bring your own NMJL card to the table). Watch each section — and your whole card — fill in over the season, and unlock the Mahjong Master celebration when every line is complete. BUILT FOR THE REAL TABLE Seat 2, 3, or 4 players — you're always seated at the bottom Six-step Charleston tracker with skip options for the Second Charleston and Courtesy Pass Automatic counterclockwise turn tracking with manual override anytime One-tap Mahjong declarations and lifetime win history Longitudinal card-line progress, section by section, with a season-long completion celebration Backup and export your history (JSON/CSV) anytime — your data stays yours No account or sign-in required to start playing SIMPLE, HONEST PRICING $4.99, once. No subscriptions, no ads, no in-app purchases — and each year's new NMJL card configuration is included at no extra charge.
