Most people consider roulette spins to be totally random. But the truth is it’s nearly impossible to design a roulette wheel that generates truly unpredictable spins. This is why roulette wheel designers constantly modify their designs. After all, a significant amount of players understand and exploit the vulnerabilities that make spins predictable enough for sustained profit. While wheels have become more difficult to beat, they are still governed by the same laws of physics, and will likely always be “beatable”.
On their websites, wheel designers claim their wheels generate “highly random” spins. After all, they’re selling something. But behind closed doors, they acknowledge that even brand new wheels exhibit long term predictable patters that can be exploited. I’m not talking about defective (biased) wheels that lead to certain numbers spinning more than others. I’m talking about predictable patterns on any new or old wheel.
Below I’ll explain some of the basic principles that make spins predictable. It is nowhere near an exhaustive list. Keep in mind the income of professional players relies on keeping certain secrets from casinos, so I can’t reveal everything. On this note, on my site I explain how my players can use my full system without risk of leaks, but here I’ll stick to the topic:
Diamonds are the metal deflectors situated around the wheel. For each direction, note which diamonds are hit by the ball. You will notice on almost every wheel, the ball hits some diamonds more than others. These are called “dominant diamonds”, and they are caused by a combination of factors including:
Wear and tear on the ball track (where the ball rolls): Unless the casino rotates the wheel on every spin (no chance), it is inevitable that the dealer’s release of the ball will “roughen” the ball track at the point of release. This causes imperfections on the ball track which is coated in a type of hard plastic. In fact even NEW wheels have sufficient ball track imperfections.
Wheel not levelled: the table that holds the wheel only needs to be very slightly uneven, and the wheel will exhibit dominant diamonds.
International government laboratories have conducted official studies for the casino communities and found that for there to be significant dominant diamonds, a wheel only needs to have one edge 1-2mm higher than the other.
Given that casino staff level a wheel with imprecise manual equipment, and there are always ball track imperfections even on new wheels, it is very rare for a wheel to not have significant dominant diamonds. Dominant diamonds are not “random”. And anything that is not random on the wheel inevitably contributes to the predictability of roulette spins.
Ball Bounce and Scatter
When the ball falls from the ball track, exactly what it will do on that spin is uncertain. But let’s say over numerous spins you monitor how the ball behaves when it falls from the ball track. Check perhaps 30 or so spins, and you will notice the various type of ball falls such as below:
BALL FALL TYPE A: on 10 spins the ball hits dominant diamond solidly then comes to rest on the number 5-6 pockets from the number that was beneath the diamond when the ball hit the diamond. For future reference, let’s call this particular number “number A”. Carefully read this part again so you understand.
BALL FALL TYPE B: on 5 spins the ball just ‘clips’ dominant diamond, then hits the next diamond before falling and bouncing 8-10 pockets
BALL FALL TYPE C: on 8 spins the ball hits a diamond other than the dominant diamond
BALL FALL TYPE D: on 5 spins the ball misses all diamonds and bounces very erratically
BALL FALL TYPE E: on 2 spins the ball falls from the ball track, then runs several times around the rotor rim before even hitting any pocket.
Let’s just assume Types B,C,D & E result in completely unpredictable ball behavior. This does not matter because we still have 10 occurrences of TYPE A where the ball falls in a reasonably predicable way. This is where we get that slight increase in accuracy we need.
Now let’s say we knew a way to predict which number will be under the dominant diamond when the ball falls. Perhaps you see where this is heading. Let’s recap and put each of the above parts together:
So out of 30 spins, you can’t accurately predict the winning number even if you know where the ball will fall from the ball track. But on 10 of the spins, you can. And with a reasonably high degree of accuracy. We don’t care about the other 20 spins, because with the 10 spins we will still have enough accuracy to overcome the unfair payouts (house edge). This is absolutely critical to understand.
