The answer to this question is complex and can only be determined through scientific study. However, there is some evidence that casinos may cheat on roulette.
One reason for this suspicion is that the odds of winning a given bet on roulette are not always what they appear to be. In fact, the chances of winning a bet are usually about 2 in 36.
However, if the casino has installed a system that allows it to predict which numbers will come up next, its advantage in betting on those numbers can increase the chances of winning by as much as 50 percent.
Some people argue that casinos cheat on roulette by using this system to increase their profits. Others contend that cheating is simply not possible given the number of variables involved in playing the game.
Nonetheless, the suspicion remains and further study is needed to conclusively determine whether or not cheating takes place on roulette tables around the world.
