VP Tutor works fine. If for some reason you are expecting to win or have some system, just think how much money you are saving by finding out the computer version is the same as the real game. (or course minor variations in the pay tables and the various versions of the game)

The chances of getting any hand, on a up and up computer version of the game, which is RANDOM, are the same as the real machines.

Video Poker payout odds are based on the pay tables and the cards are dealt at random.

You can find VP Tutor cheap and maybe free, online.
