The game tilts at once or will not start.

Game tilts or will not play: tilt switch jammed

Cause: The plumb bob or ball-roll tilt is stuck closed, often after the game was moved.

Checks

• Check the plumb bob hangs centred and the ball-roll tilt is clear.

Fix

• Free and re-centre the tilt.

Systems

• Electro-mechanical
