Benefits of technology

[0003]An improved roulette wheel with less chance of bias in accordance with the present invention includes an independently spinning wheelhead, an independent spinning cone and can also include an independent spinning lower ball track. Adding additional random elements that affect the path of the ball reduces the affect that any single element will have on the outcome.

Problems solved by technology

Roulette wheels can have a bias, or develop a bias, due to faulty manufacture, loose pocket dividers and / or wear.

Embodiment Construction

[0009]Persons of ordinary skill in the art will realize that the following description of the present invention is illustrative only and not in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons.

[0010]FIG. 1 shows a conventional roulette wheel 10. To play roulette, the croupier (dealer) first spins the wheelhead 14 in one direction and then spins the ball (not shown) in upper ball track 11 in the opposite direction. Upper ball track 11 is slightly tilted toward the middle, so that as the ball slows in the upper ball track 11, gravity will cause the ball to fall out onto the lower ball track 12. Rigidly mounted on the lower ball track are horizontal and vertical ball deflectors 13 designed to disrupt the smooth path of the ball and add a random variable to the path of the ball. As the ball continues to slow, gravity causes it to move toward the wheelhead 14. Mounted as part of the wheelhead are thirty-eight pockets 15 separate...

Abstract

A roulette wheel includes a central spindle, a wheelhead and turret unit freely rotatable around the central spindle, a cone freely rotatable around the central spindle independently of the wheelhead and turret unit, and a lower ball track. The lower ball track can be stationary or can be freely rotatable around the central spindle independently of the wheelhead and turret unit and of the cone.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to an improved roulette wheel with less bias. It has been estimated that about 30% of all roulette wheels will show some bias. That is to say certain numbers will win more times in a given number of spins than statistically predictable. Roulette wheels can have a bias, or develop a bias, due to faulty manufacture, loose pocket dividers and / or wear. Players have been known to clock wheels to identify wheels having a large enough bias to guarantee winning in a reasonable number of spins.[0002]In order for a roulette wheel to be fair to all players, there is a need for an improved roulette wheel that reduces the probability of bias.BRIEF SUMMARY OF THE INVENTION[0003]An improved roulette wheel with less chance of bias in accordance with the present invention includes an independently spinning wheelhead, an independent spinning cone and can also include an independent spinning lower ball track. Adding additional ra...
