BamBoast sits beside your physical American Mah Jongg game — tracking the Charleston, whose turn it is, and every card line you Mahjong, so you can stay focused on the tiles.
BamBoast never watches your tiles or judges your hand. It just keeps you oriented, one tap at a time.
Follow the Charleston pass by pass — First, Second, and the Courtesy Pass — without losing your place.
Designate East and BamBoast tracks the counterclockwise turn order. Tap any seat anytime to correct course.
Declare Mahjong in one tap. Watch your total wins and your progress toward completing every line on the card.
Four screens, one focus: helping the game move, not slowing it down.
Choose 2, 3, or 4 players and BamBoast draws the table to match — you're always seated at the bottom. Name your friends or just start playing.
Six mandatory First Charleston steps, an optional Second Charleston, and the Courtesy Pass — each one a single reversible tap.
Designate East, then tap a seat each time a turn passes. The last player glows pink, the next player glows green — and you can always override.
Every win counts toward your total. Optionally assign it to a generic numbered line and watch each card section — and your whole card — fill in over the season.
The official NMJL card patterns are copyrighted, so BamBoast never displays them. Lines are tracked with strictly generic numbering — Line 1, Line 2, Line 3 — inside the standard section names you already know. You bring the card to the table; BamBoast brings the tracking.
When the last unclaimed line on your card finally lands, BamBoast marks the moment properly — without ever touching your history.
No. BamBoast is a companion app for a physical Mah Jongg game already in progress. It doesn't deal tiles, simulate an opponent, or check whether a hand is valid — it just tracks the Charleston, turns, and your wins.
No. The annual card's hand combinations are copyrighted by the National Mah Jongg League. BamBoast tracks progress using generic numbered lines within the standard section names only — you always reference your own physical card for the actual hands.
No. BamBoast is built for the table: gameplay tracking, win history, and card progress all live on your device. There is no account to create. Export a backup from Settings if you want a copy for safekeeping or a new device.
You get the Mahjong Master celebration — and your history stays intact. You can keep logging wins for the rest of the card year, and everything carries forward when the next year's card rolls in.
