The JoB 9-6 strategy works fine on JoB 9-5 and 8-5 machines. I think playing 8-5 JoB is comparable to playing slot machines. At that level Slots may be a better choice when they have huge pots. However the 8-5 does allow you to practice the VP strategy; there is no strategy advantage, but you could hit some good hands and maybe a Royal.
Looking over how you get points at the different casinos I go to for video poker the best place is $2 =1credit Another is $10=1 credit And another place wouldn't tell me but said it was a combo of time played coin in and frequent visits they said if I didn't play at least one hour per visit I should not put my card as this would actually worsen my status I may quit playing there
