Then on the next spin, you increased your bet to $20 to cover the loss. What you actually do is make two completely separate bets – one of $10, and one of $20. But the reality is all betting progression does is change the amount that you risk on an individual spin.Įxample: Say you bet $10 on red, and black won. Instead, they use ineffective approaches such as increasing bet size to cover losses. This is called betting progression, and it may seem like a good idea at first. Roulette is all about where the ball lands, b ut most roulette systems don’t even consider the winning number. The problem with most systems is that they don’t increase the accuracy of predictions. The only way to beat this “house edge” is to predict winning numbers with better than 1 in 35 accuracy. In other words, you must increase the accuracy of predictions. This is unfair payout is called the “house edge” and it applies to all bets to slowly drain your bankroll. So even when you win, you still lose because you are paid an unfair amount. A win pays 35 to 1, but the odds of winning are 1 in 37 because there are 37 numbers.
