If your pay table does not have a high rate or return, move around to different games until you find one with an acceptable rate of return. The odds will be the same on each table if they have the same pay table, so stick with the one you are on.
The other categories pay similarly, but the full house and flush will pay more on a 'Jacks or Better' game. A '9/6 Jacks or Better' paytable is the best because the rate of return is 99.54%, meaning the casino only keeps. Different games will have different rate of returns, meaning some games, if you win, will give you a higher percentage of your money back and others will give you a lower percentage. There are dozens of different video-poker games in casinos.
