For time being we have lowered the house edge to 0.5% giving you more chance to win. Good Luck!
When I enter 50 in the "Odds" field, the "Payout" field is shown wrongly as 1.98.
But when the bet is made, the multiplier will be shown correctly as 1.99 with profit correctly calculated.
So the house edge is set correctly, but displayed wrongly before the bet is made.
Yeah multiplier will show 1.98 but code executes 1.99 so 0.5%, it's because the game doesn't completely handle lower edge than 1 so it's hard to change without going through the whole code.
0.5% House Edge is a limited time promotion.
