Yes I did buy it but that's incorrect. Your multiplier is calculated by your total win divide by bet amount which mine is at .10c, it's not based off 10 dollars. You pay a premium for the bonus which is 100x your bet amount so if you want to subtract my bonus buy, then my multiplier win is 2342x
If the casino has a "Live History" winning bet.
Your multiplier will be used how much money you are spending, so in Live History winning bet your information bet will be 10$ Spending and x23.42 multiplier. I already winning by buying feature and almost all of the casino will share your winning on their Live History winning with how much money you are spending not current stake bet you are choose while buying the feature.
