Most slots follow a theme and have icons that represent various things, such as numbers or card suits.

The payout schedule for a slot machine is usually displayed on the machine, along with its maximum bet and denominations.

The slot is the portion of code that executes a function or a group of functions, and it can either be called from another thread, or executed independently from any other functions in the same application. This is in contrast to an object or a class, which is defined in terms of the methods and properties that it can implement.
