Because it was from buy feature that cost him $10 and he won $482.3 so mathematically it is correct to say x48.23 instead of x4823
In most casino where there is a bet history, his win will be recorded as x48 as well as the calculation is based on what he spent to buy the feature.
my last attempt to convincing you haha you see when i get a x1 coin on MT2, its .10 x 1 = .10c . this is how you get the multipliers, its based off the bet amount
.10 x 4823 = $482.3
it's not $10 x 4823 = $48,230
I know about it very well, I know that the multiplier on the screen of the MT2 is based on the base bet amount not based on how much you spent for the buy feature.
Speaking about winning multiplier in general (mathematical logic), when you spend $10 for a single bet and your winning amount is $482.3 then the multiplier of your bet is X48.23.
For sure the winning multiplier on the screen of any game will always based on the base bet, not based on the cost of the feature.
