A slot is an opening into which something can fit. He was trying to slot a CD into the CD player.

In computing, a slot is an area in which a piece of code can be executed. Slots can be used to organize workflow and prioritize tasks, leading to higher productivity and improved communication between team members. The term is also used in reference to a specific place on the ice during a hockey game, where the goaltender can be found. The low slot is considered the best place to shoot, since it offers the highest chance of scoring without a deflection and allows wingers and centers to get a straight-on view of the net.

Despite their relatively recent introduction to casinos, slots have become the dominant source of revenue in many casino resorts. In fact, they account for upwards of three-quarters of casino gambling revenue. While they aren’t as complicated as some other games, players may encounter problems such as a malfunctioning “tilt” switch (which makes or breaks a circuit to change the machine’s payout), a faulty coin sensor, or a paper ticket that has a barcode but not a cash value.

To play a slot machine, the player inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode, then presses a button to activate a reel spin. When symbols line up on a payline, the player earns credits according to a payout table. The number of winning symbols and the amount of credit awarded vary by machine and theme.
