You may win by calling a discarded tile (Jokers cannot be called)
Clearly say "Mahjong!" and reveal your full hand
Wins from a self-drawn tile (from the wall) score double
An incorrect exposure results in a dead hand and the win is forfeited

Pause briefly to allow others to call
Keep your rack neat and easy to read
Acknowledge and celebrate the wins

Don't

Draw from the wall before your turn
Change or reclaim a discarded tile
Peek at other players' racks
Pressure players to move faster

Quick Tips for Beginners

Choose hands with simpler requirements to start (fewer pairs, no concealed sets)
Stay flexible — avoid locking into one hand too early
Pay attention to discards to help guide safe plays
Early in the game, Winds and Dragons are often safe to discard (unless needed)
Spend time getting comfortable with the card — it gets easier with practice
