If you only believe in the rotation of a real land casino, anyone can walk in and play, this is for you. The only downside is that sometimes the table is busy and the wheels don't rotate very often, although there are other wheels that can rotate more often.
Basically the wheels have no edges, so the casino has no advantage during the game. The only reward is that when you win, you pay 10% of the bonus to the casino. See the picture below and you will find that there is no zero on the table.
