  1. One historical instance concerned 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 via the reject chute into the payout tray. This particular scam has turn out to be obsolete outcome of} enhancements in newer slot machines. Another obsolete method of defeating slot machines was to make use of a light-weight 1xbet source to confuse the optical sensor used to count coins during payout.
