Slot machines are electronic gaming devices that allow players to place a bet on the outcome of a spinning wheel or the combination of symbols that appear on the wheel. They are also known as one-arm bandits because of their early mechanical lever design.
These days, slot machines can be found in various sizes, shapes, and forms in online casinos offering a huge range of themes, features, payouts and entertaining games. Most of the fully digital slot machines used today are built on the same platform as video slots.
