I am using Videopoker for Winners. They gave me 2 or 3 different licences to use it on different computers. I have one travel computer, one in my office, and a replacement device. It's fantastic. The software lets me play and shows me the mistakes I make. I write down my mistakes and work on it not to do them again in the future. No matter how many cheat sheets you are using, it doesn't help much if you are not aware of your weakness and work on it until you master the difficult hands. Every single mistake you make adds up to a bigger cut in return in the long run. Also, you will miss cards from time to time because you get distracted, tired, etc. Sometimes it's a sticky button that doesn't hold the card the way you want it. Summary: Even with year long practice my game is not better than 99 per cent accuracy. I still take it and play because it's still the best option in the casino as long as they give me points and comps from time to time.  However, without hitting your share of Royals over the course of time you will be on your own.
