Recently some companies have released multi=denom games on the same progressive. In that case the odds have to be the same relative to the bet. ie. A $1 denom game with a max bet of $3 will have the same odds as the $0,01 game with a max bet of 300. If a two coin $0.25 game was on the same progressive it would be six times the odds of the dollar and penny game.
With that said the payback percentages of the games do not have to be the same, just the odds of the top jackpot.
