Some people think that if a real slot machine has been played for a long time without giving out a win, it is about to enter a hot cycle where it will pay out a lot. This is not true. Both online and offline slots use a random number generator to determine the outcome of each spin. Each spin is different and has no bearing on the next spin to follow. Online slots do, however, offer Progressive Slots just as real slots, where the jackpot continues to grow. .
