The odds of winning at a slot machine are very low, so it is important to set limits on the time and money you spend gambling.

To play a slot machine, you must first insert cash or, in the case of “ticket-in, ticket-out” machines, a paper ticket with a barcode.

When a winning combination appears, the machine pays out credits according to the pay table.
