I know a website that has multiplayer games and it shows the result of each game in mD5 hash mode before playing .
so It is the only trustworthy website to make money.
take a look and share your idea :
www.headortailbet.comIt's a decent site with the hash mode generated after every bet but my suspicion is that it may not be as trustworthy as it may look on the surface. You could easily have a different coding interface masked by the surface displayed to the player. It's just that I'd be wary of this not being 100% trustworthy.
