Video Poker Strategies

All in Everytime
Every bet should be all in, meaning the maximum. Just play the ones where you can afford the maximum on. If you can afford a dollar per hand play a dollar, if only 25 cents play that machine instead. This is important to do, because if you land a big hand you want to have the maximum payout.
Make a chart
Play slowly and mark each card of in your chart. Then when you get say two kings and two fours. You look at the chart and there are four decks being used, there are four kings left and ten fours. This is an easy decision leave the kings and shoot for the quads.
Discard cards the algorithm will not expect
The algorithms used in the online casino video poker games are designed to not pay out more than is necessary. Also to make sure the shuffle is as random as is possible. The first is accomplished by studying human behaviour and taking for granted that people play video poker the same as normal online poker. So if they have two pair, they will be glad with the two pair and hope for a full house. The casino will pay a full house any day with its mediocre 15-1. But if you discard one pair and go for the four of a kind that pays out much more and is far better. Each hand should be played to make a four of a kind, Straight Flush or Royal Flush. This is hard to do but will payout more in the end. All it really needs is some discipline.
