A narrow notch, groove, or opening, such as a keyway in machinery or a slit for a coin in a vending machine.
The slot in a game is a mathematically determined event, and the software that powers it chooses when to win based on its maths design. It can be triggered by a random number sequence or by some other event that happens during the course of the spin, such as the player pressing a button on the machine, a fixed time or total staked, or a jackpot size.
Each slot has a pay table that lists the payouts for various combinations of symbols. The higher the number of matching symbols, the bigger the win. Some slots also have bonus features. This information is typically listed above and/or below the area containing the reels on a physical slot machine, or in a help menu on an electronic machine.
In BigQuery, a slot represents virtual CPU capacity that is used to run queries. You can purchase slots to increase the number of concurrent queries you can run. Slots are available with both capacity-based and on-demand pricing models. You assign slots to projects, folders, or organizations in pools called reservations. A project that is assigned a reservation can use any remaining slots in the pool. Projects can also inherit assignment from their parents in the resources hierarchy. Idle slots do not appear in the reservation list but are available to run jobs when needed.
