Many players take care to play their hand for all it's worth, memorizing which tiles have been discarded by the other three, trying to work out what's in their hand and which tiles they're waiting for, and minding not to "let off a firecracker" and discard just the tile they need to win.
因此許多人打牌講究「做牌」﹘﹘不但要記得其他三家曾經打出什麼牌、現在各家手上有些什麼牌、還要猜到他們在等什麼牌，自己可千萬別「放砲」，平白讓別人撿了便宜… … 等等。
