JOKER POKER – Also know as ‘Joker’s Wild’, is played with a deck containing 53 cards in which one of them is a joker and can be used as any card when drawn. The lowest possible winning hand is a pair of kings, and Five of a Kind and a Wild Royal Flush are added to the the mix just as with Deuces Wild. Again, if the pay table is set correctly, the player actually has a 0.64 percent edge over the house with perfect strategy. There are also self-explanatory sub-variations of Joker Poker known as Kings or Better, or Two Pairs or Better.
Once I put $100 into a $0.25 machine and played it for a while.  I played it down to zero credits, and then I hit Four of a Kind, which saved me.  I played that down to zero again, and then I hit Four of a Kind again.  I played it down to zero credits a third time, and then hit Four of a Kind a third time!  But that was the end of my luck.  I didn't get it a fourth time, I just went bust.  Still, that was pretty unusual.
Video poker is a very volatile game, about four times as much as blackjack. In any form of gambling, short-term results mostly depend on normal mathematical randomness (what some might call luck). However, in the long run, results mostly depend on skill. If you play a game with a return of 100.76% perfectly, that does not mean that you will have a 0.76% profit every time you play. The 100.76% is an EXPECTED return. Much in the same way, if you flip a coin ten million times, the expected number of tails will be five million, but it is unlikely you will hit five million on the nose. Actual results will vary significantly from expectations, but the more you play, the closer your actual return percentage will get to the expected return.
