In aviation, a slot (also known as an authorization) is a period of time in which an aircraft may take-off or land at a specific airport on a given day during a specified time period. The concept is important to air traffic coordination because it helps prevent the kind of repeated flight delays that can occur at busy airports, where too many flights are trying to take off or land simultaneously.

The slot machine is a type of gambling machine that uses a reel to display symbols and a central screen to initiate play. Historically, these machines used mechanical operations and a lever to spin the reels, but modern electronic slot machines use random number generators that are programmed to weigh particular combinations of symbols more heavily than others. Generally, the more paylines a machine has, the higher the chances of winning, but this also increases the cost of each spin. Newer video slot machines have touchscreens that enable players to select their preferences. A slot that offers a virtual reality experience is sometimes called a VR slot. This kind of slot provides an immersive and lifelike gaming experience, but it requires a special headset.
