Whether you are playing the roulette in the live casino or online, a lot of people think that you really cannot win that much when you play. That is because there are so many factors that might influence the outcome of the game.

While that is true to some extent and luck can certainly be a factor, this doesn’t mean that you cannot win the game. You cannot base it purely on luck because there is some math involved.

In fact, in today’s article, I will tell you how you can win at the roulette by using what is known as the number bias.

What is Number Bias?

Simply put, the number bias is the human tendency to favor ‘round’ numbers or numbers that are within a particular range that are either odd or even. As is the case with the roulette, you can either choose to bet on red or black or you can choose the numbers 1-18 and 19-36. So, how does this take effect when you play the game? Always keep in mind that the pockets or the areas where the ball may land are subject to physical properties (we are talking about the live version of the roulette). That means that the glue might not be holding its own anymore or that the pockets are not aligned or something like that. By using number bias, you select the odd or even number combination based on the physical features of the roulette itself.

Now you might think that this strategy is futile since the casino will always inspect the table before play, but that is usually not the case. If anything, all they do is clean the table and they rarely inspect the table for any dents or physical deformities.


If you are playing the European version of the game, the house edge would be 2.7% (5.4% for the American version).

Wheel Clocking

This is the part where you influence your betting decisions based on past data. When you arrive at the casino, do not place your bets just yet. Allow a couple of plays to finish and take note of the winning number for each and every round. This strategy is known as wheel clocking and it can really help you increase your chance of winning by studying the relationship of where the ball lands and how frequently lands on that particular number or on that particular color.


I suggest that you clock the wheel for at least 10 rounds. This way, you will be given a good sample size so that you can tell the frequency of where the ball lands. This is also a great opportunity for you to find any biases. Keep in mind that the type of ball used would influence the outcome of the game. Anything that is metallic is bouncier than plastic, so you have to factor that into the equation as well. Just remember, let a minimum of 8-10 games play out so that you can get a somewhat accurate data for wheel clocking and analysis.
