See below for a diagram (image / picture) of each roulette wheel layout, including European and American roulette wheels. You can use these images however you want, provided the copyright notice is not removed.
The Sequence of Numbers
You can see in the pictures above that the sequence of numbers is different for each wheel. Below it’s in text form for use in software like system testers:
Single-zero (European) wheel: 0,32,15,19,4,21,2,25,17,34,6,27,13,36,11,30,8,23,10,5,24,16,33,1,20,14,31,9,22,18,29,7,28,12,35,3,26
Double-zero (American) wheel: 0,28,9,26,30,11,7,20,32,17,5,22,34,15,3,24,36,13,1,00,27,10,25,29,12,8,19,31,18,6,21,33,16,4,23,35,14,2
The Differences Between American and European Wheels
If you look at the diagrams, that’s really the only difference. It’s just there is an extra pocket on the American wheel (the double zero), and the sequence of numbers is different.
The payouts are all the same, but because of the extra pocket, the American wheel has a higher house edge. This means you have a better change of profiting on a single zero European wheel. Specifically the house edge on the European wheel is -2.7%, and 5.26% on the American wheel.
Is there any difference in the wheel design?
Besides the visible difference in the pockets, NO. In fact you could change the pockets of any wheel by changing the rotor, then you’ll have changed the wheel type. The part with the pockets that spins is called the “rotor”. The rotor is designed to be interchangeable between wheels, at least when they are from the same manufacturer. This is because rotor sometimes develop defects from wear and tear, and the defects cause some numbers to spin more than others. This is called roulette wheel bias. And one of the measures casinos take to prevent it is by regularly changing rotors between wheels.
Roulette wheel bias is not always caused by the rotor. In facts it’s from a combination of things. Some types of bias only happen when a specific combination or rotor and wheel base (main part) are used together.
How to use the roulette wheel pictures
Any method that works by predicting roulette spins involves physics. And it is only possible by predicting sectors or regions of the wheel. So when you are applying any method, keep the roulette wheel layout picture visible. This helps you know how far the prediction was from the winning number.
It may sound like a mundane concept, but comparing wheel areas is important because it enables you to assess a roulette system’s effectiveness with greater accuracy. And assessments can be done in less time. Otherwise, you would need to rely on a statistical analysis alone.
How to memorize the roulette wheel layout
Naturally the more you work on roulette wheels, the more you’ll memorize. Your memory works on principles of association, although the layout of roulette numbers appears random without logic. It is not essential to remember all the numbers, but it makes professional roulette strategies easier to use. Below are some tips to help you memorize the roulette wheel layout:
- Start by learning the numbers either size of zero
- Each day, learn another group of numbers that are next to each other. Choose a number you personally like so it’s easier to remember.
- Once you have learned a group of numbers, remember to review them regularly. For example, don’t just forget about them for weeks or you’re more likely to forget. Your mind needs to be taught what to store in long term memory. And if you regularly request information, it will more likely become part of long term memory.
- Learn the numbers at 90, 180, and 270 degrees (four corners). At least then you can better piece together other groups of numbers you have learned.
