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.
