A narrow notch, groove, or opening, as in a piece of machinery, a door handle, or a slit for a coin in a vending machine. Also: a position in a series or sequence, as of appointments or jobs; a position in the game of slots.

The slot is an important area of the ice hockey goal where center and wingers have a clear view of the net. This makes it easier for them to get a wrist shot past the goalie. It is also difficult for defenders to deflect shots from the slot.

In a slot machine, players place cash or paper tickets with barcodes into a designated slot (in “ticket-in, ticket-out” machines) to activate the machine. The reels then spin and stop to rearrange symbols, and if a winning combination is displayed, the player earns credits according to the machine’s paytable. Symbols vary by machine, but classic symbols include fruits and stylized lucky sevens. Many slot games have a theme, and the symbols and bonus features are usually aligned with that theme.

Slots generate upward of three-quarters of casino gambling revenue and are the driving force behind campaigns to expand legalized gambling. They are the most popular form of gambling, and studies show that people who play slots become addicted faster than those who gamble on cards or bet on sports. They are especially common in online casinos. Unlike their mechanical ancestors, modern slot machines have video screens and accept player loyalty cards instead of cash.
