Video Poker - Full pay games - Deuces Wild

"Deuces Wild" is a variation of video poker in which all twos are wild. (Wild cards substitute for any other card in the deck in order to make a better poker hand). In Deuces Wild, the payout for a four of a kind makes up approximately 1/3 of the payback percentage of the game, and a four of a kind occurs on average approximately every fifteen hands. Deuces Wild can be found with pay schedules that offer a theoretical return as high as 100.762%, when played with perfect strategy. It is also available with other pay schedules that have lesser theoretical returns:

Hand	1 credit	2 credits	3 credits	4 credits	5 credits
Natural Royal Flush	300	600	900	1200	4000
Four Deuces	200	400	600	800	1000
Wild Royal Flush	25	50	75	100	125
Five of a Kind	15	30	45	60	75
Straight Flush	9	18	27	36	45
Four of a Kind	5	10	15	20	25
Full House	3	6	9	12	15
Flush	2	4	6	8	10
Straight	2	4	6	8	10
Three of a Kind	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.
