Online slots games are computerized versions of the classic fruit machines you’ll find at all good casinos. With online versions of these much-loved games, there are additional features such as wild symbols and scatter symbols, as well as interactive bonus rounds and much more. Every online slot game uses a random number generator to create random sequences every millisecond of the day. Every time a player clicks spin, the RNG produces a new random series of numbers. Online slot games have no memory, meaning no tracker is in place to record a player’s wins and losses. While, a random number generator (RNG) is an algorithm that produces random numbers. In video games, these random numbers are used to determine random events, like your chance at landing a critical hit or picking up a rare item.
