To discern if it is a smart bet, you have solve the problem based on the game's variance, the e.v., and your bankroll. Practically all AP's are aware of the first formula known as the kelly criterion (kelly bet or kelly formula, etc), where you bet based on your mathematical advantage. There are two and only two wealth creation formulae - all the other wealth creation formulae are derived from these two formulae. I may sound like I dont understand EV, but I still am not sure if these are a smart play compared to say Basic Strategy BJ where you are at a disadvantage odds wise, but still win on a fair number of occasions.
However my question is 'Is this a smart play'? I understand the Good Bet discussion, but with the RNG's and the longshot odds on top prizes on Slots, is this even worth looking at. I read on here about times when a slot machine is EV+ based on progressives.
