If there is really anything that gambler should be grateful to 1win for, it's basically for providing the platform, there is nothing to be grateful to the casino for in terms of them allowing the user to make multiple winnings in one night, if we say that he should be gratful to the casino for allowing that to happen, it simply means that the casino have the basic power to choose who wins on their platform and who doesn't, and this totally goes against the whole provably fair gaming system thing.

So, congratulations to the winner, luck was simply on his side that very night he encountered all of this wins, this is one of the beauty of playing slot games at times, multipliers likes this is as good as impossible to win from sport betting, because this can only be seen in parley bets and winning parlays is very hard, most especially ones that have more than three of four games.
