Over the years, many different systems have been developed. To give you a glimpse into the different roulette online strategies, here are some roulette systems. They are all based on the theory of probability.

## Roulette strategy: red bet

A roulette system that carries relatively little risk is the “red bet” system. You bet a small amount on red and double it every time the ball does not fall on a red colour until you make a profit. In addition, you always bet the minimum amount on black and double it when the ball falls on “0” (or “00”). Within the roulette systems, this is the most well-known variant. The risk, in this case, is quite low, but the possible winnings are also quite limited.

## Roulette strategy: columns

This roulette strategy requires a bit more money, but it also allows you to win more. You bet a certain amount each round on one of the columns with a payout of 2-1. On the second column, you bet double the amount, and on the third, even quadruple. Thus, each round, you double your bets in order to recoup any losses. Within the roulette strategies, this is a more risky strategy, but on the other hand, it can also be very profitable.

## Roulette strategy: one-hit wonder

In addition to the strategies of steadily increasing the stakes in roulette, you can also opt for more stability. This roulette strategy is played by picking a number and sticking to it for the next few days. This way, you have a chance to win 36 times your bet and thus only need to win once every 35 turns to at least break even. It is, therefore, a relatively safe way of playing that will not cost you much money. On the other hand, the roulette system will offer big differences in the winnings, making it possible to earn a lot or very little.

## Roulette Strategy: Memory

This roulette strategy requires a bit of memory since you cover all the numbers with chips every turn, except those from the last three turns. Unlike other roulette strategies, this one assumes that the same number will never be spun, thus increasing the chances of winning a bit further. Thus, the chances are higher that you will make a profit at the table. It doesn’t guarantee a win, but it allows you to structure the game as with other roulette systems.
