The Return on Investment (ROI) Concept

I like to think of returns made from roulette in terms of a return on my investment. The ROI concept is simply a way of relating the amount of money earned to the amount of money at risk. If you invest $1,000 in a bank, leave it there for a year and make $30 in interest, your ROI would be 3 percent. When gambling, it is useful to think of your ROI as the return you earn on the money at risk.

Bankroll is Investment

At its most basic level, I like to relate the amount of bankroll used in a game as the amount of my investment. Win goals, loss limits, and ROI are all based on the amount of your buy-in. For some gamblers, "buy-in" is not equal to their investment in a game. They may start out giving the dealer $200 to convert to chips, lose those chips, give the dealer another $200 and after losing this amount as well disgustingly throw in a final $100 in currency to convert to chips. Here the original buy-in of $200 does not equal the total amount risked, which is $500.

I don't recommend that you play this way. Generally, your original buy-in should be the total amount you are willing to put at risk in this gambling contest.

With our Roulette System, many other factors are tied to the amount used in a game, including the size of your wagers, the spread between your smallest and largest wagers, your loss limit, your win goal and your ROI for a game.
