This is designed mathematically as the probability of what may transpire.Ĭasinos are able to adjust the payout percentage of a game based upon how the slot manufacturer set the game up and on local laws. Payout Percentage for slot machines effectively means how much money on average over the lifetime of a slot machine, it pays back to you – in percent.įor example, if a single slot machine brings in $1 Million Dollars ‘Coin In’ and pays out $900,000 ‘Coin Out’ – then it has a 90% payout percentage (or 10% goes to the casino as profit).
