This will not change your life but it can make it alot easier.
In this thread I will explain the Martingale system on roulette. 
After this system is explained I will show you my results! 
I made alot of money with this system and it made my life alot easier. 

If you are betting on black versus red or odd versus even, then try the following strategy: each time you lose, double up the amount that you bet the first time and then bet on the same color until you win. This is called the Martingale Strategy.

For example, let's say you bet $5 on red and it lands on black. On your next turn, bet $10 on red so that you can win your money back and make a profit. If it lands on black again, double your amount again, betting $20 on red. Continue doing this until the wheel lands on red (which it inevitably will), to win your losses back and gain a profit.
Start off by betting the minimum amount that your table allows. Remember that some tables have a maximum amount you can bet, meaning you may reach the maximum before you see a win.

This strategy requires that you have enough money to be able to afford doubling up each time. I would suggest at least 75 to 100 bucks. 

The proof of it is down below :) Now I will show you some sites that I used to make the money.
