Jacks or Better	1	2	3	4	5
Theoretical Return	99.679%	99.679%	99.679%	99.679%	100.762%*

*Notice the gap between the payoff for a Natural Royal Flush played with 4 credits vs. one with 5 credits. The payoff schedule for most video poker machines has a gap like this, such that players who do not play with the maximum number of credits at a time are playing with a negative theoretical return.
