This pattern continues and always nets you a dollar when you win. And if you first win on your fourth bet, then you lose a total of $7 ($1 + $2 + $4) but make out with a $1 profit by winning $8. For example, if you lose the first two bets of $1 and $2 but win your third bet of $4, that means you lose a total of $3 but recoup it on your win-plus an additional dollar of profit.

Continue doubling ($1, $2, $4, $8, $16, etcetera) until you win. Here’s the strategy: Bet $1 on either color, and if you lose, double your bet and play again. (Real roulette tables have some additional green pockets on which you lose, giving the house a slight edge.) We’ll also suppose that the table has no maximum bet. But if you lose, you lose your $1.) And, for simplicity, assume that you really have a 50–50 shot of calling the correct color. (That means if you bet $1 and win, you win $1. For years, mathematically inclined minds have tried to turn the tables by harnessing their knowledge of probability and game theory to exploit weaknesses in a rigged system.Īn amusing example played out when the American Physical Society held a conference in Las Vegas in 1986, and a local newspaper reportedly ran the headline “Physicists in Town, Lowest Casino Take Ever.” The story goes that the physicists knew the optimal strategy to outwit any casino game: don’t play.ĭespite the warranted pessimism about beating casinos at their own games, a simple betting system based in probability will, in theory, make you money in the long run (with a huge caveat described below that I’m compelled to warn you about now, lest you read only half of this article or half of its headline).Ĭonsider betting on red or black at the roulette table.

Beneath the varnish of flashing lights and free cocktails, casinos stand on a bedrock of mathematics, engineered to slowly bleed their patrons of cash.
