No, it is not. The statement that video poker machines become “due” at some point is simply a misconception in which unfortunately many players tend to believe. The reason why this is not the case is that all video poker machines and video poker online games use a Random Number Generator. This device produces a sequence of numbers which correspond to a particular card value.
Every time the numbers are generated in a completely random manner and therefore, it is possible to get a Straight Flush two consecutive times or don’t get it at all during that particular session. It should be also noted that the RNG doesn’t take into account the previous outcome of the round when generating a new series of numbers.
