The One to Eighteen Roulette Bet
In roulette, a one to eighteen bet is when a person bets on the pockets numbered one to eighteen. This kind of bet is an example of an outside bet. An outside bet is the kind of bet where large sets of numbers, colors, or a range of numbers are bet on. These kinds of bets generally have smaller odds against winning, but because of this higher probability for victory, outside bets have slightly smaller payouts.
On the other hand, an inside bet is where a person bets on one number, or a small set of numbers that have been grouped together in certain positions on the roulette table. The chances for winning on an inside bet are much smaller, and the odds are more challenging, but the good thing about inside bets is that they normally have much larger payouts; reflecting how much a person is actually risking when they make these types of bets.
On the one to eighteen outside bet with an American roulette wheel, a person's odds against winning are 1.1111 to one. If and when a person wins, their payout will be one to one; that is, for every dollar that they had bet, they will also get back one dollar, and they will also get back the amount that they had originally put in.
On a single spin, the total amount of profit that a person can make if and when they win betting on the one to eighteen on the roulette wheel, therefore, is the exact same amount of money that they had bet. A roulette wheel has a total of thirty-six alternating red and black numbered pockets, marked from one to thirty-six. Aside from that though, American roulette wheels also have two more numbered pockets.
These pockets are green, and marked zero, and double zero. Because of the house edge, the odds against winning in any roulette bet will always be slightly higher than the payout that a person can receive. This is because when calculating for the payout, a casino does not normally count the two green pockets, even if they still factor in when calculating for the odds against winning in a particular bet. It is the presence of these green pockets that make the house edge -or house average- possible.
It is not that detectible on a one to eighteen bet, because of its already low odds against winning, but on a single number, or Straight Up bet though, it is quite obvious, because when betting straight up, the odds against winning are thirty-seven to one, but a person can only win thirty-five times the amount that they had originally bet.
