Throughout history individuals have claimed
to discover a system to beat roulette. For hundreds
of years these systems have been re-discovered and tested-and
many of them amount to sheer folly. They have exotic names like
Fibonacci, Martingale, DAlembert and Labouchere. They all
involve increasing your bets as you lose-primarily on the even money
wagers like red or black.
Martingale is keyed to doubling your wager
after each loss until you finally win. When you do win, youll
only be one unit ahead. When it comes to DAlembert, its
a technique related to increasing one unit of wager each time you
lose and cutting back a unit when you win.
Whatever the system, the weakness is that
you must risk large sums of your bankroll to win one single unit.
Youll hear of others like the Reverse Labouchere (also called
the Reverse Labby), where youll be increasing your bets continually
until you reach the house limit.
In modern times, players have searched for
biased wheels where some defect in the wheel itself
creates an edge because the ball seems to fall in a certain sector
more often than it should on a random basis. This apparent bias
allows an edge to alert players and most modern casinos are well
aware of disastrous consequences of using a biased wheel and constantly
guard against it.
