Online slots are games that can be played on a computer or mobile device. They use random number generators to determine results and can be played at any time, from anywhere in the world. There are a variety of different companies that create online slot games. Some of the most popular include IGT (International Game Technology) and Microgaming. Some of these companies have developed some of the most popular online slot games in existence, such as Cleopatra and Wheel of Fortune.

The game play in online slot is very similar to that of traditional land-based slot machines. A player inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode, and then activates the machine by using a lever or button (either physical or virtual). The reels then spin and a result is displayed on the screen. The player can then choose to continue playing, either by using more cash or by selecting a bonus round.

While there are a number of theories about choosing the best slot machines at brick-and-mortar casinos, many of those same strategies do not apply to online slot machines. There is no way to know whether a particular slot machine is ’hot’ or ’cold,’ and even if you find one that pays often, there is no guarantee that it will continue to pay out for any extended period of time. It is recommended that players only gamble with money they can afford to lose.
