A single person may not have unlimited money, but the public as a whole does. And the casino still wins. Any "strategy" can work over a small sample size, but overall, the player loses.
Again, it is precisely misunderstandings like the ones debated over the last 2 pages that allow casinos to make billions of dollars a year. The math is undeniably against the player, yet folks insist on spinning scenarios and ideas in their heads to justify why they "should" win.
Roulette is the most simple wager game imaginable, essentially one step in complexity above flipping a coin, yet the general public can't wrap their heads around how the odds actually work. Gambling is truly a tax on stupidity, and it pays guys like me. So thank you everyone haha!
Right. The only way for one person to walk in guaranteed to win is if they have infinite money and the discipline to stop once they win the first time using the 'double-down' method. But yes, even a person (or as you said, the public) with infinite money will lose over time if they don't stop after the first win.
