Hello. I met a casino with 0% house edge. Can I trust them?
If some casino is claiming 0% house edge then they are making false statement I think. The casinos earns from the house edge you may find the casinos with less house edge but I don't think you will find any casino without the house edge.
I've seen some casino's that have a 0% house edge on their dice games, I'm not sure how they get their profits but they aren't making false statements afaik.
Some casinos have a 0% house edge on some of their games, not all. They make enough profit from their other games to make up for the losses.
Crypto-Games has a +EV lottery for example.
