Considering that casinos have run all these scenarios past actuaries and computers for decades, it’s a safe bet to assume they are confident none of these systems will ever make any but the luckiest players in the universe wealthy. Still, it’s fun to take a chance with your money and see what happens. When you look more closely at how these strategies work, they all share a common theme: expect a better result next time.
Betting systems that try to leverage failure invoke the player’s fallacy I mentioned above. The random nature of the game doesn’t guarantee your money will last as long as you need it to. Some people argue that the unfavorable percentages in the game make it more reasonable to place higher bets. If you bet you entire bankroll on a single spin, including even money bet, you could walk away a very happy winner. The prudent player leaves the table while he still has enough cash to try another game.
