Free tickets to lottery and reward points that you can claim stuff with and even the lambo is all paid by the 5% house edge. I mean some people complain about the rate of it but honestly at the places you play that gives you 1% house edge or so they do not give anything else, that is it, you play on 1% house edge and you lose.
i dont complain on the given rewards and tickets but i sometime ask myself that its nearly impossible to reach a certain amount of rewards to claim those gadgets . now i decided to use all my reward points to roll without captcha .
you can earn more on playing on lower house so its okay if they dont have other features but its also okay to play with 5 percent house but you will get to earn something in return .
