MAHJ: Learn American Mahjong

MAHJ is a complete, beginner-friendly course for the American (NMJL-style) game. No experience needed: you'll go from "which tile is that?" to sitting down at a real table with confidence.

WHAT YOU'LL LEARN
• All 152 tiles by sight — craks, bams, dots, winds, dragons, flowers, and jokers
• How to read the card and match your tiles to winning hands
• Setup, building the wall, and dealing — with hands-on, interactive tables
• The Charleston: what to pass, what to keep, and why
• Jokers, calling, the courtesy pass, scoring, etiquette, and common mistakes
• 18 bite-size lessons, each taught one piece at a time

PRACTICE UNTIL IT CLICKS
• Tile drills, hand-building games, and a daily puzzle
• Play a full hand against friendly AI bots — start to finish
• A Hand Analyzer that suggests the best hands for your tiles
• Ask the Coach anything about the rules — answers grounded in the lessons

LEARN WITH YOUR TABLE
• Start a crew — invite friends with a share link and track everyone's progress together, so your whole group is ready for game night. Mahjong takes four; bring yours.

START FREE
The first lessons, tile drills, and daily puzzle are free. One simple, one-time purchase unlocks all 18 lessons, play vs bots, the Coach, and the Hand Analyzer — no subscription, nothing that auto-renews.
