You can't find a zero house edge in the current time, you will find nohing if you keep trying that because this is a business model and both party will try to get profit so if there is zero house edge, where are they trying to get profit? Anyway for current situation dice-bet have offer 0.7% house edge which is the lowest you can get. Except there is event like I participated before, they offer 0% house edge but only limited time
