A slot is a dynamic placeholder that waits or calls out for content. When the slot is active, a scenario can feed it content either by using the Add Items to Slot action or pointing it at a repository with a bunch of content (a slot repository).
In the physical world, slots are the openings in which coins and tokens are inserted into a machine to play. This concept has made the jump from the physical to the digital space, where casino games have become more popular and the term slot has taken on a broader meaning.
For instance, in an NFL football game, a slot receiver is the third-string wide receiver who typically plays on passing downs and is primarily responsible for receiving passes from the quarterback. In other words, a player like Wes Welker is playing in the slot to make sure that he gets open on those long routes and isn’t just standing around waiting for someone to throw him a short pass.
Pay tables are the list of rules and payouts for a particular slot game. They normally display all of the symbols in a slot along with how much you will win for landing a certain combination. They also include information about bonus features that can be activated during a slot game.
The original pay tables were displayed directly on the machines and were easily readable due to their size and simplicity. Today, they’re generally embedded into help screens.
