Is It Possible to Predict the Upcoming Numbers in Roulette?

Making predictions that can swing the odds in your favor is one of the most crucial aspects of day trading. Those looking to make profitable trades utilize more information and use this to gauge likely short-term trends. 


It’s by applying knowledge and experience of the markets that day traders can get ahead. This is one of the main factors that distinguishes the practice from gambling. 

When it comes to casino games like roulette, the situation is a little different. Players rely on pure chance when making bets and cannot influence the odds. 

That’s what most people think anyway. But is it actually possible to predict the upcoming numbers in roulette? This article explores the truth of the matter. 

  1. Doing the maths – the odds don’t change

If you’ve ever been to a casino, you might notice some players at the roulette tables sitting with notepads to record the sequence of numbers that the roulette wheel produces. They are hoping that by paying close attention to what has already been done, they can get a better idea of what is due to come next. 

The problem with this so-called method of predicting roulette numbers is that the maths doesn’t work like that. In reality, each spin is completely independent of the last. No number is ever “due” or “not due”. 


For example, if the number 27 has dropped three times in the last ten spins. It still has exactly the same chance of dropping again in the next spin, regardless of previous frequency. 

This works similarly the other way around. If you have been watching red/black and the red hasn’t dropped for five spins in a row, that doesn’t mean it’s any more likely that the next spin will produce a red. 

Roulette’s creator, Blaise Pascal himself, tried to solve the game using mathematical formulas and never succeeded. Meanwhile, Einstein himself pointed out that each trial is independent. 

  1. A word about online roulette

Roulette is exactly the same game whether played live or online. The rules, odds, and payouts are the same. Just as in live roulette, it’s not possible to use mathematics or to observe the sequence of numbers to get an edge. 

The main difference between live and online roulette, is that live roulette uses a physical wheel and online roulette uses a digital wheel along with a random number generator that ensures fair odds. The methods of number predictions mentioned below, then, can not be applied to online roulette, as each relies on a physical wheel and/or dealer. Hence, when taking a dive into a roulette casino, it’s best to embrace the game’s randomness, understand the odds, and enjoy the game by sticking to your limits. 

  1. Other ways to make roulette predictions

There are a few other known methods for making predictions for the ball’s resting position on a roulette wheel. These involve the use of physics to predict the ball’s speed and movement. 

Aside from one highly illegal method, all of the following suggestions are inaccurate and, in short, don’t work. Still, it’s interesting to see how each would play out: 

  1. Visual predictions

This method relies on being able to weigh up the speed of the wheel and ball to predict where it will land. Proponents wait for the moment when the ball is released, but before betting is closed, to quickly weigh up the physics and place their chips. 

The idea is not to predict an exact number, but rather a section of the wheel. Still, this is a highly inaccurate method of predicting roulette numbers. In reality, it’s very unlikely that any human will be able to make these calculations to any meaningful degree. 

  1. Roulette prediction devices

Enter roulette prediction devices, the computer version of what we described above. Prediction devices utilize lasers and microchips to gauge the speed of the wheel, velocity of the spin, and it’s more likely landing positions.

Again, the idea here is to predict an area of the wheel to bet on. In this case, it’s actually possible to gain an edge as the computer can predict the outcome with much more accuracy than a human. 

In order to setup a roulette prediction device, you’d need to have an overhead camera pointing to a table connected to a microchip that sends data to a device such as a smartphone. You can see this is not easy to do. On top of this, the use of prediction devices is highly illegal and will get you barred from casinos, possibly worse. 

  1. Rigged wheels

Back in the day, roulette players used to look for imperfections on roulette wheels; scratches, dints or imbalances that might cause the ball to land with a bias for certain slots. This was never an exact science to begin with, and it’s unlikely players managed to gain a long term edge. 

This method of roulette number prediction is even more unlikely than it used to be. Casino tables are well made and regularly maintained. No reputable casinos are going to keep broken or rigged wheels around for too long. 

  1. Dealer signature 

This method of roulette number prediction relies on working out the dealer signature, meaning the speed at which they usually spin the ball. The idea here is that dealers either consciously or subconsciously spin the ball the same way every spin. 

There could be a bit of truth in this. Dealers work long shifts and muscle memory will play a part in how they spin the ball. 

Still, there’s very little chance players will be able to work this out in a meaningful way and convert this into an edge. On top of this, dealers are trained not to create patterns in roulette.
