In order to be able to recognize a boiler error in Roulette, players have to locate a so-called distorted roulette wheel. This is a roulette wheel where certain numbers fall more often than others. Whoever recognizes a boiler error and thus a distorted roulette wheel, can possibly earn high profits and use this advantage for himself. In technical jargon, boiler error is also referred to as "wheel bias".
In mathematical terms, a biased roulette wheel is a wheel that produces results that differ from those expected under probability theory. In this case, either the Casino has manipulated the roulette wheel, or the wheel has defects or damages that lead to the unbalanced results. In practice, of course, it is very difficult to detect boiler defects in roulette. To do this, players often have to spend several hours looking at the kettle and statistically record the results in each case.
As mentioned above, it is not easy to detect kettle errors. First of all, you should know that there is basically plastic in the recesses of the roulette wheel, which is fixed here with a special glue. If the glue then loosens in the course of time, the surface is also changed. As a result, the ball behaves differently in the roulette wheel. In rare cases, there may also be errors in the production of the roulette wheel, which can ultimately lead to wheel faults.
Of course, casinos strive to prevent boiler errors. For this purpose, all numbers of a gaming session are documented by the casino and analyzed afterwards. In most cases, software checks here whether certain numbers occur more frequently than others. If this is the case and accordingly there is a Risk that it is a distorted roulette wheel, then the casino will initiate appropriate checks. In the online casinos, of course, there can be no boiler errors.
