What is a Slot Machine?

A slit or narrow opening, as in a keyway in a door or a slot for coins in a vending machine. Also, a position in a series or sequence.

A machine that accepts cash or paper tickets with barcodes (in “ticket-in, ticket-out” machines) to activate a series of reels that spin and stop to rearrange symbols. The player then earns credits based on the number of matching symbols along a payline. Symbols vary, but classics include fruits, bells and stylized lucky sevens. Many slot games have themes, and bonus features align with the theme.

In casinos, machines are grouped by denomination and style. High limit machines are often in separate rooms or’salons’ with their own attendants and cashiers. Most video slots have a ‘HELP’ or ‘INFO’ button that walks players through the various payouts, play lines and bonus features.

There’s a common belief that if a machine hasn’t paid off for a long time it’s due to hit soon. This is false. Casinos don’t program machines to be either hot or cold, and even if they did, it would take too long to adjust the entire system to flip a switch for one machine. The fact is, if a machine had gone a long time without paying out, most people will pass it by and find another “hot” machine. Besides, if the casino did program machines to be hot or cold, they would have to open up every single machine in the property, and that could take 45 minutes.
