How to Never Lose at Roulette Again
The government’s national weights and measures laboratory investigated the technique. It is thought the cheats first identify a “biased” wheel, where the ball appears to commonly drop in roughly the same zone. They also look for signs on the wheel of a “manageable scatter”, which means that when the ball strikes a certain number, it will usually fall into a neighbouring pocket. The unpublished report concluded: “On a wheel with a definite bias and a manageable scatter, a prediction device of this nature, when operated by a ‘skilled’ roulette player, could obtain an advantage when used in a casino.”
Using this, a guy can gain from 20% to 100% over the casino, depending on how skilled he is. We wouldn’t recommend buying one and using it in Vegas, however. Not if you value your arms.
