Deep Stats
Tracking stats over lots of spins, like 200 or more, shows good patterns. Using the Kelly Criterion, you can manage your money well, choosing how much to bet based on your edge and how much money you want to risk.

Even with a house edge, knowing odds and spread of results betters your game plan. Rules on how big your bets should be and a system for betting smart helps structure your play.
