Protect the tray
Match a waiting tile before four different faces fill the tray.
Think ahead without rushing
Classic strategy opens layered boards. Calm Mahjong adds one more choice: protect the four-space tray while uncovering deeper tiles.

Three priorities
Match a waiting tile before four different faces fill the tray.
Remove tiles that reveal the greatest number of hidden choices.
Balance the left and right edges so one side does not become trapped.
A calm move order
There is no timer. A short scan often reveals a move that both completes a pair and opens the board.
Compare real layout shapes →If a tile already waits in the tray, look for its free matching face before adding something new.
Prefer a pair that uncovers a lower layer or releases a blocked left or right side.
Three different tray tiles leave no room for an unrelated fourth tile. Pause and find a match.
Opening only one side can hide useful choices on the other. Keep the whole layout moving.
When you want a hand
