A slot is a position in a sequence, series or set. It can also refer to:

A casino game that spins reels and pays out winning combinations based on a random number generator. Slots can be played for fun or real money. They are available online and in land-based casinos. They can be themed after comics, novels, films, video games, sports or culture, and are usually based on a simple mechanical principle.

Traditionally, slot machines had three to seven reels and a lever or button to activate them. Modern electronic machines have more reels, a computer to control them and various bonus rounds. Some of these have additional mechanical devices, such as a separate rotating wheel to award credits, or a physical version of the reels that can be spun to win prizes.

Modern slot machine manufacturers use microprocessors to assign different probabilities to each symbol on a given reel. This allows them to weight particular symbols, so that they appear (along with blanks) more frequently than other symbols. To the player, this can give the appearance that a winning combination is “so close” to being struck, whereas in reality the probability of hitting it has nothing to do with how often the symbols appear on the reels.
