Roulette is a game of chance and there is no defined way to beat the table. However, over the years, many players have developed systems which give an advantage to the players and increase their chances of winning. Many systems were developed to beat the table. Some popular systems are the Martingale System, Labouchere system and the Dozen Bet. You can try all this different strategies without risking your bankroll by playing our roulette games for free.

The Martingale system

A winning streak or a losing streak in Roulette means nothing. Because, if you win five rounds continuously on ‘even numbers’, there is no guarantee that you win in the sixth round on betting again on ‘even numbers.’ The law of probability holds the same for even the sixth round and any outcome is possible. However, according to this system, losing streaks do not last long and in order to win and also compensate the previous loses, you have to double your bet after each round. For example, if you bet $25 on red and lose, you will lose $25. Increase your bet to $50 and spin for red again. If you lose again, you lose $25+$50 = $75. Now double your bet again to $100. If you win this time, you will win $100 and cover up for the previous loss, as well as make an additional $25 on the win.

But do not forget to check the table limits while you set out to implement this system. You can double your bets only upto a certain point on any roulette table. So even when you are using the system, you are taking a calculated risk. For a clear understanding, suppose you have $1000 in your account at

You wager $25 on red and if you lose you will be left with $ 975. Double your bet to $50 and bet again on red; if you lose again, you will be left with $ 925.

Now, following the Martingale system, you double the bet again and bet $100, meaning your account will hold $ 825. Let us say you win. Then, your account will reflect $ 1025. Remember both your wager and win will be added back to your account. Clicking on the CLEAR button helps you update the account status.

In effect, you have recovered your total $75 loss as well as earned an extra $25.

At, you will find that the table limit is at a maximum of $250 for outside bets, and $200 for inside bets. Red being an outside bet, you cannot proceed beyond the next step. That is if you lose the $100 wager as well and decide to double it to $200, you will be taking a huge risk. Because if you lose that wager, you would have lost $375, just chasing the first $25. Even if you do win, you are only richer by $25, so is it really worth all the risk?

The Grand Martingale

Grand Martingale is much like the Martingale except that, here you not only double the bet after a loss but also add the initial bet amount to it. This system aims at higher profits. That is, if bet $25 and lose, double it to $50 and add $25 to it, to bet a total $75. If you win next round, you win $75 and cover the $25 you lost originally, plus gain an extra $50.

Let us check a live example

The initial Amount = $ 536,266.00

Bet Amount = $25, Amount Left = $536,241.00

Next Bet is double the previous bet of $25 plus the initial bet amount.

That is $50 + $25 = $ 75, Amount left = $ 536,166.00

Won the Bet, The Amount in the account = $ 536,316.00

So, the profit is $ 50 more than the initial amount $ 536,266

The Labouchere System

This is a progression betting strategy that does not require you to risk your stake. This strategy can be used if you wish to win a predetermined amount of money. List a series of positive numbers that add up to the amount that you want to win. With each bet, stake an amount equal to the sum of the first and last numbers on your list. If only one number remains, that number is the amount of the stake. If your bet is successful, remove the two amounts from the list. In case the bet fails, move the amount lost to the end of the list. Continue this process until either the list is completely crossed out, at which point you have won the desired amount of money or you have run out of money to wager.

For a clear understanding, let us assume that you want to win $ 55 and take numbers 1 to 10 for the list. That is, if you want to win $55 on European Roulette, make a list of positive numbers whose sum is $ 55.

To simplify, let us take the list like as 1+2+3+4+5+6+7+8+9+10. Your first bet would be 1(the first number from the list) + 10(The last number from the list). The sum is 11. If you win, remove the first and the last numbers from the list. The new list would look like, 1+2+3+4+5+6+7+8+9+10 your next bet will be 11 that is 9+2.

However, if you lose the bet of the initial bet of 11, your new list will be 2+3+4+5+6+7+8+9+11.

Your next bet following the loss would be 13. (The sum of first number 2 and last number 11 from the list). Continue this process until all the numbers are crossed out, by which time, according to this system you are expected to win the target amount. This system enjoys popularity because many Roulette players find it to be an effective method to win.

Given below is an illustrative example of how this system plays itself after CoolCat casino software download takes place.

Labouchere System

Amount that is chosen to win is $ 55 (That is to make a profit more than the initial amount and less than or equal to $ 55)

The initial amount in the account – $ 536,229.00
List Bet Amount on Red Account balance
1+2+3+4+5+6+7+8+9+10 $11 $536,218.00
Won the bet $536,240.00
2+3+4+5+6+7+8+9 $11 $536,229.00
Won the bet $536,251.00
3+4+5+6+7+8 $11 $536,240.00
Won the bet $536,262.00
4+5+6+7 $11 $536,251.00
Lost the Bet $536,251.00
5+6+11 $16 $536,235.00
Lost the Bet $536,235.00
6+16 $22 $536,213.00
Won the Bet $536,257.00
Now, no numbers are left in the list and a profit of $ 28 is made.

The Dozen Bet

There are two versions of the dozen systems. One is the single dozen and the other is the double dozen system. In the single dozen bet you have to continuously increase the stake list from a minimum to maximum. The objective of this system is to bet on a single dozen before the stake list ends. There are different variations in this type of betting like betting on the same set of a dozen that appeared most in the 15 or 9 or 5 spins of Roulette wheel. In the double dozen version of the game, two dozen bets and half of the stake list size of single bet version is used.



The origin of Roulette was in France, in the 18th century. It was then believed to be a combination of several European games. The word Roulette literally means small wheel in French. Later the popularity of the game increased to the extent that many new features were added to it.

The original version of the game had both the 0 and the 00 bets and an American eagle. It was only in 1843 that two Frenchmen – François and Louis Blanc, introduced the single 0 style wheel which is now popular as European Roulette. This new wheel was invented to compete against other casinos offering the traditional wheel with both the single and the double zero pockets.

Many casino halls took pride in incorporating the Roulette wheel in their halls. Gradually the trend moved to the Internet as well and online casinos started hosting European Roulette. With advanced casino software download alternatives and sophisticated technology, European roulette has made a mark in online casinos and boosted the revenues of online casinos as well.
