Breaking the wall:

East rolls two dice and counts the corresponding number of stacked tiles (each stack includes both the top and bottom tiers of the wall), moving from right to left. The break in the wall occurs at the counted position.

To mark the break, the portion of the wall to the left of the gap is pushed toward the center of the table at a 45-degree angle. The remaining tiles to the right of the break stay in their original position on the far right. This visual cue—a cleared space on the left—serves as a reminder of which wall will be pushed out next.

If a player pushes the break all the way to the left, it may become difficult to notice, especially if the gap is small. This can lead to confusion at the end of the game when counting remaining tiles. To avoid this, players should ensure the break remains clearly visible throughout the game.
