Does anyone know which machines have shorter win cycles? That is, the number of hands you need to play until you reach a "sure win" hand, like RF. I know that most machines have cycles, like slots, and do not produce random hands. My friend and I are studying some of these machines and we''re trying to find the machine with the shortest cycle and the highest odds of winning.

As in many casino games, the cycle is determined by the potential payoff. However it is well known that there are "luckier" machines which are scattered around, in the smaller joints, and are harder to find, because the big casinos put a lot of effort into making the machine jackpots very hard to score. You can get more details at this video poker site.
The numbers are a bit scrunched but he makes a good point, you need to decide which pot you are hoping for and make your play according to that. Or you can try combining cycles but you will need an equation calculator for that…

How does he know what number is used? How can anyone know? Casino managers keep resetting and reprogramming those machines all the time.
I don’t know where this guy gets the confidence to stand behind these numbers.
