If your table’s settings get changed accidentally, you can reprogram your table easily
back to American mahjong (152) tiles.

For American Mahjong, the magic code is Game 3.

Step 1. Press and hold two DICE buttons next to each other until you hear a beep.
Step 2. In this mode, pressing the red buttons will increase or decrease the number in the console display window.
Step 3. Press red buttons until the display shows 3. That’s American Mahjong (152 tiles).
Step 4. Press and hold any two opposite DICE buttons for 3 seconds until you hear a beep.

The table will remember this forever.

Helpful note:
All game codes are listed under the felt mat when the table is open—and online here.
