What Is a Slot Machine?

A slot is a machine that dispenses coins to players for hitting symbols on the reels. There are a variety of ways to win, including combinations of three or more matching symbols. The symbols on the reels zigzag across in different patterns, and winning combinations can pay out large amounts.

A pay table lists the symbol values and the amount of credits you will receive for landing a particular combination. The pay table can be found on a screen above the reels, or on a separate panel inside the machine itself.

The pay table will tell you how much a winning combination is worth, and may also explain any special symbols that appear on the reels. The pay table will also provide information about any bonus features, and sometimes even jackpots.

Return-to-player percentage (RTP)

RTP is a term used to describe the percentage of money returned by a casino over time, measured as a ratio to the average amount of money spent. This is important because it can help you decide if a particular slot is worth playing.


A slot machine’s payback is a ratio to the average amount of money it takes to keep players seated for a given number of spins. Licensed casinos are required to publish this ratio on their website, and it is a good indicator of whether or not a slot machine is worth playing.


A taste is a small amount paid out to keep a player seated and continuously betting on the same slot. It can be a lot smaller than the minimum payout, and is often based on a combination of how many times a player has spun the reels and the time it takes for the machine to pay out.
