There is yet another kind of roulette, which is made in the following manner: One-half of the small pieces of metal which form the pockets for the ball are made a trifle longer than the others, lettered on the diagram E E E. After the stakes have been placed, if the proprietor wishes the ball to fall in a red color, it is necessary for him merely to throw the ball around to the right hand, and if he wishes it to fall in the black, he casts the ball toward the left. The players may observe that he throws the ball in a different direction on different occasions, but the action appears to be so trivial that it excites no suspicion.
Another fraudulent contrivance used in playing this game consists in the gambler’s having two centers to a wheel, apparently identical, one of which, however, is “square” and the other “faked.” This device is known to the members of “the profession” as the “double center.” The “square” wheel is used at first, and, at an opportune moment, the “fake” is substituted, after which the sharper has everything his own way. This wheel is operated on very much the same principle as the “needle wheel,” for the construction of which the reader is referred to the chapter containing a description of that device. A system of levers radiating from the centre of the apparatus is operated by a rod terminating at the edge of the table. By bringing to bear the requisite pressure, these levers cause fine needle points (lettered C C C on the diagram) to rise through the cloth, one coming up in front of each alternate compartment on the rim, thus obstructing the entry of the ball and causing its course to be so changed that it shall fall into one of the next adjacent divisions, as in the case of the “needle wheel” above referred to.
It is easily perceived that the players can have no possible chance when playing against such roulettes as these, and there is a large number of them in use all over the country.
This game is a favorite one with nearly all non-professional gamblers, not only because the risk of loss involved is not large, but also because of the popular impression that it is always played “on the square.” As a matter of fact, it usually is conducted fairly, although, as will be explained, sometimes bare-faced swindling is resorted to by the proprietors.
