What a stupid scam attempt..I mean they even quoted each person's prediction and then edit that person's prediction by themselves (as only they could edit their own post of course) so they can't even claim that what they did was just a mistake

Spiroll looked dodgy right from the beginning with their unrealistically high jackpot, and this just confirms that this is a deliberate scam. If casino can't afford $50 reward, imagine what will happen if anyone wins any bigger amount of there?
