In computing, a slot is a place where a peripheral or expansion card can be inserted. This is typically done by using a special connector on the motherboard and is sometimes called an expansion bay.

There are many types of slots available, including PCI slots, ISA slots, and AGP slots. The type of slot required depends on the motherboard and type of card, and the number of cards that can be installed is often limited by the amount of memory on the system.

In a slot machine, a player inserts cash or, in the case of “ticket-in, ticket-out” machines, a paper ticket with a barcode on it. Then, the machine activates by means of a lever or button (physical or virtual) and spins to rearrange the symbols. If the player matches a winning combination, they earn credits based on the pay table. The pay tables are displayed on the screen of the machine and are easy to read. They can include an example of each symbol, together with how much is won for matching three or more. They may also explain any special symbols, such as the Wild symbol, and how they work.
