Slot machines are games in which the player is awarded credits for winning combinations. To play these games, players insert money in the machine or can buy paper tickets with barcodes. When the lever or button is pressed, the reels spin and credits are earned according to the paytable. The symbols used in these machines vary depending on the theme, but classic symbols often include fruit, bells, and stylized lucky sevens. Bonus features are also common and are usually aligned with the theme.

Usually, this is done through the help menu of the machine or by searching online. Keep in mind that these percentages will not change throughout the night, and that some casinos will require special paperwork for changes to the payout percentage.

To change the payout percentage of a slot machine, a casino must first get the approval of the State Gaming Commission. The casino can then reapply to the State Gaming Commission to change the payout percentage. This way, the state can protect slot players’ interests.
