What Einstein actually meant was that there is no mathematical trick that can help you win at roulette. Each spin is an independent trial and, in the long run, the casino will win. This is different to a game such as Blackjack where the probabilities change as cards are dealt.

If you want to know what is the probability that the coin will come up heads, then that would be: heads / (heads + tails) = 1/2 = . 5. Likewise when playing an even money bet at roulette, that option covers 18 of the 37 possible outcomes: 18/37=. 48648649.

An overwhelming success or victory. Fortuitous accomplishment or unexpected triumph achieved through chance or discovery.

Who has won the most money gambling? Kerry Packer, an Australian gambler and a billionaire, won $40 million in a single Las Vegas night in 1995. Not only did he break the blackjack record, but he did it for the second time in a row. His lucky streak lasted only 40 minutes, but we wagered approximately $250,000.
