If that paytable is correct and it's not a Class II game, the return is 100.83%. Playing 5 hands with a $1 denomination would have lower variance than 3 hands with a $2 denomination.
If it's Class III, the machine's signage will usually say something like "Game uses one 52-card deck"
If it is Class II, it might say something like "Game simulates one 52-card deck" and/or will mention bingo, and/or there will be a bingo card somewhere on the display. There may also be a "genie card" or "match card" mechanism, restoring a winning hand on the draw if you accidentally or intentionally discard a dealt winner.
The reason I am suspicious is because 9/5 Bonus Poker is unheard of. It would return 100.3174% without the Double Super Times Pay feature, and 100.83% with it, if cards were dealt fairly. I can't help but suspect that there is something amiss; casinos don't typically offer games with such a huge player advantage. I can't even see IGT including 9/5 Bonus Poker as a paytable the casino could choose to offer, unless it was a Class II machine.
Is the game in a tribal casino or a commercial casino?
