Do not fall for the trap of a gambling site marketing themselves as having 0% house edge. It is unrealistic, period. Operating a gambling site is a business and where does the site's revenue come from? Yes from the edge they have in the games. It is what allows them to operate for the long run and it is their bread and butter. They will be hit by short term losses thru lucky players winning but they still make money from them in the long run because the house edge makes the gambling site a winner.
Not all people are going to win in gambling though but with 0% house edge i never know that such thing exist unless they have something to do with their game and abuse us, but we never know the condition but there is one site that have 0% house edge. Dont even know they are for real or now but player played there without any complaint. May be they have a great bankroll on their back to hold their big loss later
