Hey Patricia
I did find on wizardofodds a practice page for just about every type of video poker. Just hit 'More Games' a few times to see all the games. When you find the one you want, click on the little box at the top 'Warn on Strategy Errors' and you can see the best play for every hand. Here's the link, it has Joker Poker and now has Double Joker Poker among all the other popular VP games
