Attempted Contribution - Fever Aces

[tableplay]

On the other hand mickeycrimm with his discussion about slot machines is the only one who has provided info which is informative. So kudos to mickeycrimm.

Fair Enough. Here is my attempt at a contribution.
Fever Aces is a VP game from Grand Vision gaming where if you end up with 3 or more aces after the draw you get to pay (at the same denomination and # of coins) for eight more games with a multiplier of 2x,3x,4x, or 5x on all of the eight games (3.1 is the average multiplier according to a Grand Vision staff member). Before beginning the eight multiplied games, the player picks one of five cards at random to determine the multiplier for the 8 games of the fever round.
Here is some YouTube footage of the game posted by a civilian (or so I would assume from the dialect of the speaker) who has inadvertently stumbled upon this game in the wild (and uploaded it about a year ago):

Analysis:
So as you can see from the Excel spreadsheet analysis depicted in the screenshot (using the civilian's YouTube paytable), the player must have a multiplier of at least 3.34 (average multiplier confirmed by Grand Vision employee is 3.1) in order to be at break even, because the base game has an 80% payback (per the civilian footage). I've also included in the screenshot the ROR of the bank roll required to get a draw of 3 aces (so it's actually slightly better than this since you could get 4 aces to qualify the fever round). For example, you have an 89% of getting a 3 ace draw (and starting a fever round) before ruin, if you have a bank roll of $6.75 playing penny denomination with 5 coins in). Please let me know if I have made any analysis errors.
