A slot is a designated time for an aircraft to land or take off at an airport. Aircraft are authorized to use this time if it is necessary to meet certain conditions, such as tight parking space or high runway throughput. Slots are traded and can be quite valuable; one was sold for $75 million in 2016. These slots are also issued by air traffic management organizations, such as EUROCONTROL, as part of their role in capacity and flow management.

The pay tables of slot machines tell the player how much they will receive if a series of symbols line up. In older machines, the pay tables are listed above and below the wheels. On video slots, the pay tables are displayed in the help menu. It’s important to know the pay table for each game you play, so you can maximize your winnings. However, remember that it’s possible to lose more money than you put in. Slots are not like other forms of gambling.

Each slot must have a mapping between its value and its type. The builtin amountOfMoney and builtin duration type map to each other. If you need to map different types of slots, you can create custom ones. For example, you can create a slot for “locations”. You can mark the location of an utterance. If you’re looking for a specific place, you’ll use the location slot. It’s also possible to use regex patterns to map phrases to slots.
