There is no one definitive answer to this question as it depends on the specific roulette table in question and the level of sophistication of the person rigging it. However, some methods that are possible include cabling the wheels so they rotate in opposite directions, positioning magnets under certain numbers on the wheel so they will always stop on that number, or even installing a computer chip that will automatically place bets for the person rigging the table.
While these methods are possible, they are all relatively complex and would require a significant amount of technical expertise to pull off successfully. As such, it is generally not recommended to rig a roulette table – even if someone were able to do so – as it is likely to result in losses for the person doing the rigging and could even lead to criminal charges being filed.
