In aviation, a time period during which an airplane may take off or land at a specific airport, granted by air traffic control as part of a coordinated schedule. Slots are a critical part of managing air traffic at busy airports, helping to avoid repeated delays caused by too many planes trying to take off or land at the same time.

Unlike the mechanical reels found in older casino machines, modern electronic slot machines have multiple reels and can accept many coins per line. They are operated by inserting cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode into the machine and activating it with a lever or button (physical or on a touchscreen). A microprocessor inside the machine assigns a random combination of symbols to each reel, and when those symbols line up along a payline on the machine’s face, the player receives credits based on the payout table listed on the machine.
