Slot machines are machines that give out credits when certain symbols line up on a pay line. Some symbols represent many different things, so it’s essential to know what each symbol represents before you begin playing. Most slots have a pay table listed on the machine’s face, above or below the spinning wheels. You can also find this information in the help menu.

Modern slot machines are much harder to predict, as they use computer programming and are therefore more flexible. This flexibility means that the machine can have more symbols on its reels. While old mechanical slot machines were limited to five symbols per reel, modern computer-powered machines can have as many as 20 symbols. This allows players to play more games for the same money.
