Seeing this type of triumph on the part of a player, the transparency that Rollbit has with its games is undoubted, in addition a payment of this level is quite high for many of us, it is a victory that shows that the casino allows you to make very large bets and that Rollbit fulfills its commitment by paying. Congratulations to the player and thanks to Rollbit for sharing.
AFAIK that slot isn't owned by Rollbit, so it's not paid from rollbit's funds. It's 3rd party slot which only listed by Rollbit on their site. We do know we can win lot through slot games but we can lose a lot too on there.
