I've recently created a free video poker game that works on both desktop and mobile devices called VPKR (click to play). In addition to standard Jacks or Better and Deuces Wild modes, it also features two new games with new strategies:

Deuces Stacked
Similar to Deuces Wild, but instead of winning one prize for the best hand you can make, you win the prizes for any hand that can be made with the cards you are dealt. For example, say that you finish with 2 2 5 7 A. In regular Deuces Wild, you would get only the 2x-bet for the flush. But those cards can also be a three-of-a-kind, so in Stacked, you would get the 2x-bet for the flush and another 1x-bet for the three-of-a-kind.

Double Down
Similar to Jacks or Better, but instead of one round of betting, there are two. After being dealt the initial five cards, you can hold cards and draw for another bet--or fold the hand and avoid paying again.

I'm still working out the appropriate pay tables for each of the games, but the game is now live and available to be played.

When you get a chance, please check it out and let me know if you have any feedback on the new games, the pay tables, or the app design.

Thank You! And Enjoy!
