Page "Slot machine" Paragraph 72

Mechanical slot machines and their coin acceptors were sometimes susceptible to cheating devices and other scams.

One historical example involved spinning a coin with a short length of plastic wire.

The weight and size of the coin would be accepted by the machine and credits would be granted.

However, the spin created by the plastic wire would cause the coin to exit through the reject chute into the payout tray.

This particular scam has become obsolete due to improvements in newer slot machines.
