How casinos insure against a roulette system
The result of applying the theory mentioned in the previous section would be encouraging, as it claims that the probability of winning a bet on even chances is over 99.9%. Not bad at all for game in a casino where one expects to take chances. But the problem is that it is impossible to put this brilliant method of enrichment into practice.
Gambling institutions have a simple way not to let a game transform into one where the solvent gambler would be practically “doomed” to win. Therefore, casinos limit the maximum bet alllowed.
In any casino in the world, every table – be it a roulette, blackjack or poker – specifies the rate of the minimum and maximum bet allowed. The range between them can be 10, 30 or even 100 times. Nonetheless, every table has a limit.
The restriction of the upper limit of bets is proof of the fact that a roulette system based on the principle of repeated increases in a bet are dangerous for the casino. Take, for example, a table where the minimum bet is €25, and the maximum is €1000. Why aren’t players allowed to bet more than €1000? Is it because they will not have enough money to pay? Or because the casino is afraid that players will win and then take the money home? What difference does it make, if in the neighboring VIP-hall €2,000 bets and even €10,000 bets are allowed! Real high-rollers can agree with the casino’s administration to make even higher bets. Clearly, there’s no shortage of cash at the casino. Another principle is at work: the ratio between the maximum and the minimum. If a maximum of €10,000 is established, the minimum bet will rarely be less than €250. Casinos don’t want to allow doubling to happen more than 5 times. Otherwise the players’ chances would become inadmissibly great.
Given this restriction at casinos, different types of a roulette system have been developed to use a small range bet variation. In order to insure that the bet stays for a long time between maximum and minimum, it is necessary to consider an arithmetic progression rather than a geometrical one. This increases the bet not by several times but in several units.
