What is a Slot?


A slot is a placeholder on a Web page that either waits for content to be added (a passive slot) or that gets called out by a renderer (a active slot). This content may be HTML or a JavaScript expression. Slots can be nested to create more complex logic.

A slot machine is a game that spins reels and pays out credits according to a pay table. Depending on the game, a player can win prizes such as cash or goods. These machines also have a bonus round that gives players additional chances to win credits. Bonus rounds are often themed and have special symbols that increase the player’s chances of winning. Some slots even offer multiple styles of bonus rounds.
