Thomas Elrod Betting System
Basically, the Thomas Elrod Roulette betting system uses a debit, or due column, and a control number which is divided into the debt to arrive at the figure of the amount of the next bet. Elrod used a basic goal of 100 units for his initial debit or due. He used the figure 20 as his initial control number.

He divided 100 by 20 and therefore his first bet was 5 units.

If he lost, he added the amount of the losing bet to the debt and divided again. After a win, he subtracted the number of odds he control figure and the number of units won from the debt figure and divided again.

Elrod used the column or dozens exclusively, thus his odds were always 2 to 1 and this was always the figure he would subtract from the control number after a win.

He never allowed his control number to drop below 3. Thus, he needed two or three wins in a row at the end of a series in order to close it out and start over. He also never reduced his bets at any time.

Here is an example:

100 20 5 L 0 5 0 5
105 20 5 L 0 5 0 10

Here you start over. Obviously, there are endless variations. You don’t have to use dozens or columns. You can arbitrarily add numbers to either the debt or control numbers to reduce the amount of your bet. And, you can adapt the system to other games and types of gambling.

Obviously, the system is not foolproof. Bets will eventually rise during losing streaks. Sometimes they can get prohibitively big. Still, with a little common sense, it’s not too bad.
