Winning At Roulette
While no one can offer you a surefire, win no matter what way of winning
at roulette constantly, one of the keys to achieving this is in understanding
the mathematics of roulette. Winning at roulette can be unraveled a bit
by first reveal the secrets of the 'house edge'.
The true mathematics of roulette is that unfortunately, even when the
casinos seem to lose, they are actually winning even then. Picture a simple
$1 bet on the roulette table, on and individual number. The chance of
hitting that number on an American roulette wheel is 1 in 38, or you could
express it as 37 to 1 odds. But if you were to win that bet, you would
only be paid 35 to 1. When really, you deserve to be paid at 37 to 1.
So theoretically, after 38 spins, you'd have won on a number only once,
but note also that you would have lost two full dollars on this win. Where
did the two dollars come from? Two dollars is 5.26% of $38. 5.26% is the
house's edge on American roulette.
When we say the house edge of American roulette is 5.26% we mean that,
over the long run, the casino will take in 5.26% of whatever is played
through the table. You can work that number out intuitively as we did
above, or you can work it out with the mathematical formula for expectancy.
Expectancy is a number that represents the percentage of your wager you
expect to win or lose for a given bet. If the bet is a 'positive expectation'
one, the expectancy will be a positive number, and you should expect to
make money from the game. If the bet is a 'negative expectation' bet,
as almost every casino bet is, you should expect to lose money from the
game.
Expectancy = [odds of winning X money won] + [odds of losing X money
lost]
For example, let's run through the single dollar bet example from above.
Expectancy = [1/38 X 35] + [37/38 X 1]
= [0.921] + [0.9736]
= 0.526
or a 5.26% negative expectation
This is the same as saying that this roulette bet has a house edge of
5.26%. The strange thing about roulette is that every bet has a house
edge of 5.26%, on an American wheel. To illustrate this, let's look at
a more complicated bet. If we put $10 down on red, $10 down on the number
8, and $10 on the third column, what would the house edge be?
E = {[18/38 X $10] + [20/38 X $10]} and {[1/38 X $350] + [37/38 X $10]}
and {[12/38 X $20] + [26/38 X $10]}
E = [47.368 + (52.631)] and [9.210 + (9.7368)] and [6.3157 + (6.8421)]
= 5.263 and 5.268 and 5.264
Notice how you can't escape the house edge of 5.26%  each and every
bet works out to it. The combination of bets also has an edge of 5.26,
which we can see logically. 5.26% of each bet, combined, would work out
to be 5.26% of the total bet.
So what really is the trick to winning at roulette? We suggest that you
try to hedge your bets. So for example, lets say you were betting on black,
you could hedge that bet a little by betting on the third column. The
third column has 8 reds and only 4 blacks, so a bet there covers almost
half of the red numbers. Almost half of the red numbers covered, and all
of the black numbers covered gives you pretty good coverage.
Yes, in the end though each bet still has a 5.26% house edge, but you're
still in with better chances at winning at roulette if you play this way.
