People who think it is possible to win roulette long term, in any form, are in denial of reality or fail to understand the basic calculations involved. The mathematics are specifically built to favor "the house" and that is all there is to it. There is no magic formula that will be able to beat a game that is designed to make the casino money - that is why you see them in every single building. It is not a card game like blackjack, where if you are skilled enough it might be possible to win by counting cards. On top of that, if you are not playing with a real life physical wheel the odds are even more stacked against you, online casinos can (although they don't need to) rig the games to give a certain amount of wins or losses, by manipulating code behind the scenes.
An acquaintance of mine worked as a croupier for many years. He told me that if you don't know how to throw a ball into a certain sector, you'll never be put at the roulette table. That's why even in a real casino you can't beat roulette. Unless, of course, you're in cahoots with the croupier.
In this case, you can win at roulette ...
The player has a real chance to beat the casino if the casino is purposefully playing against another player.
The player cannot cheat the mathematics, but if the croupier is engaged in manipulations and deliberately throws the ball into a certain sector of the roulette wheel, then the player has chances. These manipulations can be detected if the player has intuition and knows how to analyze large amounts of data.
Chaos is unpredictable. However, manipulation is not chaos, it is a pattern.
A pattern is a code that can be deciphered.
