Game canvas and the game

The roulette wheel is what ultimately selects a game and the game itself. However, in order for its function, it also needs a gaming screen that accurately represents the roulette wheel’s colours and numbers.

Then, once the wheel has stopped spinning, you place a wager on the number you believe the ball will land on. You win if the number you bet on is where the little ball eventually stops after the dealer spins the wheel.


Except for zero, which is green, all the compartments on the wheel are black and red. You may also wager on a colour combination and then double your stake if the ball lands on the colour you selected.

Naturally, there are several variations of the white professional roulette balls used in actual casinos.

The roulette wheel itself contains two fundamental parts. One is a static bowl and the other is a wheel head that revolves within the bowl. The bowl has solid wood with plastic parts or covers.

However, bowl assembly consists of three parts: the bottom ball track apron, the ball track with the distinctive ball diffusers, and a shaft that supports the rotating wheel head.

The roulette wheel head is placed in the bowl so that it aligns with the top and lower ball tracks. However, the coloured numbers and pockets for the roulette ball to land on are located on the wheel head’s outside edge.

The cone is the middle component of the wheel head that steer the ball into the pockets. A turret is an ornamental element that conceals the height adjuster.

Odds on a roulette wheel

Roulette odds depend on the type of wager placed. The odds are highest for single-number stakes and lowest for outside bets such as odd/even numbers or red/black.

You will have better odds playing European roulette compared to the American variation.

It all depends on what you bet on or how you decide to play more strategically, and how you really calculate the odds yourself.
