BamBoast
American Mah Jongg Companion
$4.99 · Designed for iPad. Not verified for macOS.
Your table's quiet co-pilot for physical American Mah Jongg: track the Charleston, whose turn it is, and every card line you win. $4.99 once - no ads, no subscription.
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.
