Open Mahjong Coach

Put in your hand

Tap Set up hand and choose your tiles, or take a photo of your rack and check the tiles Coach reads before you start. To start over, tap Clear hand to empty your rack.

The 2026 card is the default. Use the gear button to change the card or the tile style.

See your closest hands

Coach lists the hands on the card by how many tiles you still need. Tap a hand and the tiles it uses lift in your rack while the rest fade, so you can see what to keep. Pin the hands you are watching; pins stay on your device.

Tap Card to see the whole card. Hold your phone sideways for three columns, like the printed card, and tap any line to pick that hand.

Get help with the Charleston

Turn on Charleston and Coach suggests which tiles to pass, keeping your best options open instead of chasing a single hand.

Keep up as you play

Tap a tile in your rack to discard it, or tap + to add a tile you drew or called. Coach updates right away, and you can undo a change if you tap the wrong tile.

Playing a two-player game? Switch to Two hands to plan both of your racks at once.
