it doesnt matter what bet size.
a) If a person has a 500 euro win on 1 euro bet its 500 x multiplier.
b) If a person has 2000 euro win on a 10 euro bet its 200 x multiplier.
c) If a person has 200 euro win on a bet size of 0 .20 euro bet its 1000 x.
so the winner is person 'c' because they have maximum multiplier win.
No minimum bet size. Only requirement it should be on Leo Vegas casino
