How to lose money on the game of roulette

Periodically on the Internet, an advertisement about how to earn money for free in a virtual casino on a roll slips on the Internet. Here are examples of spomoni.habrahabr.ru/blog/9732/, ruletka.4t.com, biznesland.narod.ru. From the point of view of the theory of random numbers, we do not have a single chance to win a casino, but the craving for freebies is indestructible. Therefore, I wrote a small roulette emulator so that you can feel everything yourself.



Results: There is no chance to win the roulette. Any win will be replaced by a loss. People from the links above earn either affiliate programs with casinos (the casino pays them a part of the money you lost) or selling for 10 ye a super secret how to deceive the roulette (why sell it if you can use it?). In general, there is no freebie, but craving for freebies is a quick way to lose your money.
