From the old "Rooward" the percentage was based on how much you are wagger on the casino and the percentage about the "Rooward" always changing sometimes 2-5% and could be sometimes 15-20%.
Wut? 15-20%? Let's say I wager $1000, I could get $150 back? Sounds too good to be true 
But that's possible if because of lossback, since you do all-in most of the time.

I tried to redeem a promo code from Roobet's Telegram yesterday however I got this message: We're sorry, this promotion has ended!
You have to be quick and claim it before anybody else since it can end in a very short time. That said, I can claim the promotion most of the time.If the post had fewer views, probably that's because users read the message from telegram's push notification.
Anyways, it was only 0.15$
