You say, "Pay attention to a biased wheel not patterns." Also: "I do not think patterns exist." Well, with the casinos knowing that a biased wheel could cost them dearly, I do not think biased wheels exist anymore. It costs them so little to keep them perfect compared to what it would cost them if they did not maintain them quite often. Even if there did exist 1 biased wheel in the world, you'll never find it. Actually, by saying patterns do not exist, is a good understanding of roulette. If you bet your money that a certain pattern will not come into existence because patterns do not exist, then how can you lose? If you arbitrarily make up a black/red pattern of 10 colors and write them down, such as: BBRRBRBRBB. That pattern only exists on the paper you wrote it on. Now, take that pattern to the casino and bet that it does not exist there as you say. You will probably be right 99% of the time. That's my philosophy, if patterns do not exist, then bet accordingly. If somebody were to challenge me with the proposition that they would give me 10 million dollars if that pattern did not repeat the first ten spins or they would take my life if it did repeat, I would jump on that challenge in a heart beat. Wouldn't you?
