Single Zero wheel

What is a ‘Single Zero Wheel’?

This is a European roulette wheel with only one zero marked on it. It is different from the American variation, which features one single zero and an additional double zero.

‘Single Zero Wheel’ Explained

Roulette originated in France and typically only featured one zero on the wheel. To this day, it is the most common wheel layout in Europe. Americans introduced the additional ’00’ to their wheels to give the house a further edge.

A single zero wheel is a better option for players since the payouts are fractionally better and so variance can be mitigated over the long run.

Roulette pays out in a structure based on odds of 36-1 for successfully predicting the ball will land on a particular single number, however as well as the numbers 1 to 36, there is a single zero on the wheel. This means there are 37 numbers the ball can potentially land on but only odds of 36-1. This means the payout is 1/37 lower than it statistically should be. This amounts to 2.36% and is often referred to as the house edge. You are free to bet on zero, however the payout is still 36-1.

With a double zero wheel, there are 38 numbers to choose from but the payout structure is still based around 36-1. This means the payout is 2/38 lower than it should be. This amounts to a house edge of 5.3%. Thus the single zero wheel provides a better option for the player over the long run.

To entice users, online casinos tend to offer the European or single zero wheel as standard as do bricks and mortar casinos throughout Europe. In America, the double zero wheel is the standard but single zero wheels can sometimes still be found in high roller rooms.
