Roulette computers are hidden electronic devices that predict where the ball will land. Legalities vary between jurisdictions although they are mostly legal, and the casino will ban you if you are caught using them because they wont tolerate consistent winners either way.
There is an enormous amount of nonsense circulating on the Internet about these devices which has been spread of scammers selling such devices. However, once you understand what these devices do and from where they achieve accuracy of predictions, you can then investigate the features of each respective device to determine if they are any better than visual ballistics. Of course roulette computer sellers still blatantly lie about what their products actually do, so unfortunately this makes it difficult to know the difference between simplistic and genuinely sophisticated technology.
What a Roulette Computer Does
In Part 2 - Visual Ballistics, I explained how dominant diamonds and ball bounce can lead to predictable spins. Essentially visual ballistics is a method to determine where the ball is most likely to fall. There are many ways of doing this, but usually it involves identifying when the ball has a specific number of revolutions to go before it hits a dominant diamond and falls onto the rotor (pockets).
Roulette computers do much the same same thing, although it is easier because instead of using your eyesight to determine ball speed, with a roulette computer you just click a hidden button each time the ball completes a revolution. This is not perfectly accurate, but still accurate enough to beat many wheels.
See video of my roulette computer being publicly demonstrated:
Are Computers More Accurate than Visual Ballistics?
This depends on the roulette computer, but for most of them, NO. The accuracy you will get with visual ballistics is typically exactly the same as a roulette computer. This is because they both rely on exactly the same principles for accuracy of predictions. While sellers of roulette computers want you to believe their devices are space-age NASA technology, most use an incredibly simplistic algorithm that literally takes minutes to write. Then dishonest sellers put a high price tag on their device, and call it the best computer available. Unfortunately players who don't understand what the devices actually do and how they are almost identical to visual ballistics are lured into buying near worthless devices.
Are There Better Devices?
Almost every roulette computer simply replicates the accuracy of visual ballistic methods. The only devices that do far more to maximize accuracy are developed by myself. I suggest you thoroughly read my sites which include detailed comparisons of various computers, then you can decide for yourself. I suggest begin with the sites below RouletteComputers.com and HybridRouletteComputer.com.
If you want to better understand how to make a roulette computer, see roulettecomputers.com/howtomake.html and the subsequent pages. It is a lot of reading and you may not understand it all, but it needs to be understood if you want to avoid spending thousands on a device that is basically no better than the free visual ballistics technique I teach.
