Barbee Street System

You bet the same amount on two of the dozens at 2:1
and half of the bet on 6 numbers paying 5:1
leaving only 8 numbers open.

This program will bet the first two dozen,
and the 6 numbers (25-30), the 5:1 play.

If you lose:
The bets will be double for two turns.

Play will continue until the bankroll is gone,
or the desired profit is made.
