I am pretty sure there is no point in adding auto roll for roulette. If you want to use auto roll like that you might as well use dice instead.

Roulette is more of a funner game than dice and that's why in a physical casino you usually have a Roulette table and no such thing as a dice table.

Whatever odds you are going for, you might as well configure your dice wagering and percentage and its kind of like dice. Basically no different than the people who want to play the lotto when they can just play dice on 9900x.
