How to Play


This is the Martingale played on both numbers.
Starting bet is your initial bet on Red and double that on Black.

Color wins, reset the bet to your initial bet.
Color loses, double the bet.

Why is different from the Martingale? 
If you reach your profit target and did not have to reset your bet,
then you will find that you have been winning your initial bet each spin.
