If you need convincing of the above, I suggest run hundreds of thousands of trials with automated software. The mistakes you don’t know you’re making It might be wise to consider what so many people have learned. Billions of gamblers have applied the principles and lost. It is a concept that is old as history itself. But keep in mind thinking that streaks will continue or end is one of the most common misconceptions about gambling. If you’re new to roulette, it may be hard to get your head around the concept. So the odds of a dozen spinning once is 12/37. Again the odds don’t change based on previous dozens. There are three dozens on the table, and 37 numbers. But it’s the same as red then red spinning, or black then black. If you want to get technical, the odds of red then black spinning are 1 in (0.4865 x 0.4865). Who was right? Actually none of us were right. I saw it differently and expected the streak to end. Some players at the table thought red was on a winning streak, and that it would continue. There is an exception that i wont explain in this article, but the statement is true in the cases of almost every losing roulette system. What I failed to realize is the odds of black or red spinning next are not affected by previous sequences. Consider again my loss when I bet on black. The odds do not change no matter how many reds or blacks have spun in a row. And it’s the same for any “even chance” bet including highs and lows, and odds and evens. So the odds of red spinning are 18/37 = 0.4865. On the European wheel, there are 37 numbers. The odds of red or black spinning in a row It is still possible such a sequence will spin, but I’ll explain more about it later. But the truth is the casino staff were adjusting the wheel and attached equipment, which gave the strange readings. It was originally published by a player who seemed to want to discredit the casino. Only many years later did I understand my delusion. I lost everything that I so proudly won earlier with my dozens betting system. This happened for the next few spins, until I eventually blew my entire bankroll. Then I said to myself I’d have to be very unlucky to lose again. After all, what are the chances of red winning again, right? Well I lost. I thought to myself that black is due to spin next. Around 20 years ago, when I had no idea about winning roulette, I approached a roulette table with around 10 reds in a row.
