Across all rulesets

Pong. Kong. Chow.

Whatever ruleset you play, the three core calls are universal. Claim a discard, complete a meld, fight your way to the winning call — Game!

PONG
碰 · pèng
Claim a discard from anyone to complete a triplet. Expose the set and press your advantage.
KONG
槓 · gàng
Four of a kind. Declare a Kong and earn a replacement draw — and bonus points in most rulesets.
CHOW
吃 · chī
A run of three in sequence. Restricted to the player on your left — the modest move that often wins the round.
