I still don't get why some people don't think you can win at roulette...

It is as simple as changing your bet based on past spins. Simple... The hard part is finding what percentage to raise and lower. I have done it and it works fine. If you pick the right percentages you can win about 80% of the time. You just have to make sure that in those times you win more than when you lose.

Anybody that suggests that the casino have a constant edge therefore can never be beaten in the long run, are kidding themselves.

I ask one question: "Why does the casino have a bet limit?".

The answer is they didn't always have. It is because people using systems beat them so they had to change the rules. Martingale for example.

So why is it such an impossibility to beat it.?
