How To Fix Pay Out On Slot Machines

Owning a vintage slot machine is one of those fun yet daunting ideas. Many old school one-armed bandits are beautifully designed and instant conversation pieces. Plus slot fans who own a machine don’t ever have to worry about losing money to the house.

However, that doesn’t mean that you can’t influence your chances by using the right betting strategy and choosing the right game to play.

For example, in Nevada, casinos are able to change the slot payout percentages by ordering a new chip from the manufacturer, the chips in the slot machines are then swapped and it is only allowed when all the appropriate paperwork is filled with the state to inform them of the change. Some of the later model slot machines support downloadable software, should a casino request a change in payout percentages the software can be sent via a central server and the slot machine can be updated without physically being opened.
