In gaming, a slot is a dynamic placeholder that either waits for content (a passive slot) or calls out to it (an active slot). The contents of a slot are dictated by either using an Add Items to Slot action or by pointing to a repository item using a targeter. While slots and scenarios work in tandem to deliver content, it is not recommended to use multiple scenarios for the same offer management panel slot.
The type of symbols and bonus features available in a slot vary by game. For example, progressive slots are linked machines that accumulate a jackpot; while flashy slots are popular for their increased chances of winning through special symbols. Many slots are designed around a particular theme, with different symbols representing the elements of that theme.
In aviation, a slot is an allocation of time at an airport to allow an aircraft to land or take off at specific times. In the past, these slots were often determined by the availability of runway space, but now they are mostly allocated as a result of air traffic management policies implemented by EUROCONTROL in airports that are experiencing congestion. The implementation of these slots has been associated with significant savings in both delays and fuel burn.
