Roulette Wheel Bias
For everyone familiar with the game of roulette, nobody can deny that this is a game of chance -- pure chance to put it into more even terms. Whatever strategy or technique you may apply at your roulette games, sooner or later the house advantage will get to you. Unless certain extraordinary circumstances occur, such as a bias on the wheel, overcoming the house advantage is next to impossible.
You could do all sorts of things; bet on your lucky numbers, bring all your lucky charms with you and whatnot -- none of those will make any appreciable difference on the outcome of the game. You can only be sure of two things when you're playing at a roulette table; it's either your lucky day, or it's not. Skills aren't essential in a game of roulette, they aren't even required.
So what can you do to increase your chances of winning then? In very rare instances, you can actually do something to increase your odds. In most cases though, you really can't do anything other than hope for the best.
When these rare occasions do pop up, there's a good chance you can take advantage of them. So what are these occasions? One is when the wheel shows a bias for certain numbers. This has happened in a number of occasions, and people did win a lot when they were able to ascertain which wheels have a bias.
There are a number of reasons why roulette wheels may show a bias. The wheel itself could be off balance. Sometimes, due to old age or misuse, certain walls or frets between numbers may rise slightly or, have a different tension compared to the other frets.
If this is the case, then the numbers in question may come up more often than the other numbers. Wheel biases happen rarely though. Even before casinos became aware of this occurrence, roulette wheels were checked and examined regularly. Also, it's not easy to spot a really biased wheel.
First off, as already mentioned earlier, casinos maintain regular check ups on their roulette wheels. So if a bias do happen, it won't take long before the casino replaces the wheel. Another reason why it's extremely hard to take advantage of wheel biases is because before you could even spot one, you would have to track play for hundreds, if not thousands of spins.
Having one number come up four times in eight spins doesn't ensure a wheel bias, for instance. Spotting wheel biases may be extremely rewarding, but for most casual roulette players, this isn't a viable winning strategy.
