I am not a big fan of raffle games. I'd like to see blackjack, roulette or maybe poker & dice with 0% house edge. But I don't know how you will manage to do that.. Also how are you going to maintain the servers if you don't take an edge?
This is also my question to the team a 0% house edge is new to my eyes because how they take to gain profit? For the maintenance of the site however even this online casino has a zero house edge it stil has a big advantages.
