I don't know whether these programs are compatible with Windows 8, but other programs that I know about are: "Frugal Video Poker" by Jim Wolf and Jean Scott; "Video Poker For Winners" by Bob Dancer; and "Optimum Video Poker" by Dan Paymar.
For "Frugal Video Poker" you could try https://www.wolfvideopoker.com/FVP.htm or you can see if the Gambler's General Store in Las Vegas or their website has it.
For "Video Poker For Winners" as well as "Optimum Video Poker" try the American Casino Guide website or get "Video Poker For Winners" through either Bob Dancer's own website or through Shoplva.com and for "Optimum Video Poker" you also could go through: https://www.optimumplay.com.
Enjoy!
