Simulated colour round

Payouts here sit just under fair odds, exactly as they do on real platforms: the two common colours cover roughly nine draws in twenty each yet return less than double, and the rare colour is priced the same way. Over a few hundred rounds that small shortfall is the whole business model. Leave the demo running and the balance drifts down regardless of how you pick.

Nothing you do in this simulation affects any real account, and no data is sent anywhere. It exists to make the shape of a long session visible without costing anything.
