Many fans of gambling who have attended land-based casinos or slot halls are probably familiar with the so-called pneumatic roulette. It is a device with the conventional roulette wheel (usually covered with glass or plastic hemisphere) in which the ball is spun not by the dealer, but by the special mechanism. The bets must be placed on the special screens that are located around the wheel.
This kind of roulette has been popular among the customers who do not trust random number generators or employees of casinos. SkillOnNet offers a virtual simulator of pneumatic roulette whose interface accurately simulates it, but the game is based on the RNG.
