I have these free play vouchers from my local casino and i can only use them on slot or video machines and i have to play through the value of the free play 1 time before i can cash out. So I've been looking around and apparently jacks or better video poker will give me the best expected return on the free play like 99.5% or something using proper play, so i want to play that but i never have before. I have like a cheat sheet that i printed off from a website telling me what to do with hands to maximize profit so I'm ok there but like how do i find out which VP machines are full pay? Are they all the same or do i have to look for something to make sure i get the best chance of maximum profit based on the payout setup of the VP machine? Thanks for your help.
