A slit or narrow opening, especially one for receiving something, as a coin or a letter. Also: an assigned position or time: a slot in the schedule.

A slot is an open area of a machine or table used to hold components for testing, such as a T-slot. A bolt or stud is then threaded into the slit to secure the component. This method of mounting parts allows for the same locations to be used for repeat tests or batch testing.

In casinos, a customer may activate the service light on their slot machine by pressing a button on the player console. A casino employee then comes to assist the customer, typically by activating a reel or bonus round display. The service light is usually bright enough to be visible from a distance and, as a result, it can prompt many other slot players to take notice.

The slot light is often referred to as the candle within slots terminology. It is a symbol that alerts casino employees to a customer in need of attention, and it is commonly found on top of the slot machine for easy accessibility. Many slot players activate the service light to call a slot attendant, but others do so for a variety of other reasons.

Linguistics[Editors’ Note: The precise meaning of this word is somewhat unclear, but it seems to refer to a grammatical function rather than a physical location or position, although it is sometimes used as a synonym for crater in the sense of ‘hole’ (cf. crater, hole). In some contexts, it may also be used as a synonym for pocket.

In computing, a position in a queue or matrix. A software application may have multiple slots for a task to execute, and the system assigns each job to the next available slot. The system may also allow tasks to be paused and resumed, or to borrow capacity from another slot. The scheduler enforces eventual fairness of slot allocation, and is able to adjust between aggressively evicting running tasks and being too lenient.

A monthly slot detail report is submitted to the Commission by each casino, and it must be reviewed and posted by the 10th day of the following month. The Commission uses the information from this report to allocate slot payments to each casino. It also reports the total amount of money awarded to customers for each month’s slot activity, including any winnings from jackpots and other bonuses. This data is useful to both customers and casinos for understanding slot machine payout patterns and trends over time. The report also includes a breakdown of each slot’s payout percentage. The slot percentages are calculated using a combination of the percentage of each game’s jackpot, as well as the number of games played and average wager per game.
