No matter your opinion of gas station slot machines, they’re gambling machines – designed to rob people out of money. But one man was accused of devising ways to trick the machines into giving him free spins – police say he altered $100 bills so the slot machine thought he had retained it, giving him multiple free games from one bill!

Though it may be tempting to think you can beat gas station slot machines by reading Michael Bluejay’s Easy Vegas site or SlotsGuy’s guide, such methods don’t actually work. All slot games are random; even those that appear to involve skill like pushing buttons in sequence don’t work that way.
