The wheel, its spindle perfectly balanced, spins smoothly in an almost frictionless manner. The standard roulette table employs up to 10 sets of wheel checks usually called chips. Each set is differently coloured; each traditionally consists of chips; and there is one set for each player. The chips usually have a single basic value, although some casinos also sell chips of lesser value. The colour of the chips indicates the player, not the value of the chips. Most casinos also have high-value chips that can be wagered at any gaming table.

Unlike roulette chips, these have their numbered values printed on them. It is possible to place the following bets in roulette: On layouts with a single zero European style , the 0 may be included in a 2-number bet with any adjoining number, in a 3-number bet with 1 and 2 or with 2 and 3, and in a 4-number bet with 1, 2, and 3 at the regular odds for these bets.

With the American-style 0 and 00, a 5-number line bet also is possible, the player placing his chips on the corner intersection of the line separating the 1, 2, 3 from the 0 and 00, with payoff odds of 6 to 1. The game begins when one of the croupiers dealers in attendance calls for the players to make their bets, which they do by placing chips on the spaces of the layout on any number, group, or classification they hope will win.

Players may continue to place bets while the wheel and ball are in motion until the ball slows down and is about to drop off the back track, at which time one of the croupiers announces that no more bets may be made.

When the ball falls and comes to rest between any two metal partitions of the wheel, it marks the winning number or a 0 or 00 , the winning colour, and any other permitted bet that pertains to a winning number or symbol.

The dealer immediately announces the winning number and its colour and places a special marker on the corresponding number on the layout.

He first collects all losing bets, not disturbing the chips that are resting on winning spaces, and then pays off any winning bets. The only exception is the 5-number line bet, where the house advantage is about 7. Roulette as played in locations other than the United States and the Caribbean is the same except that the wheel and layout contain only a single zero 0.

On the next spin of the wheel, if 0 appears again, the house collects half of each imprisoned bet; if not, it collects all losing bets and returns the original bets to any winners. Countless betting systems have been devised in order to beat the wheel.

Most of these systems centre around the even-money bets. Modern mathematical theory, as well as over two centuries of practical playing, however, have conclusively demonstrated that it is impossible to beat roulette with any sort of betting system. Because the bank retains an advantage on any kind of bet, in the long run it does not matter how a player combines or varies his bets. In practice, most betting systems redistribute the amounts of the wins and losses: The oldest and most common betting system is the martingale, or doubling-up, system on even-money bets, in which bets are doubled progressively after each loss until a win occurs.

This system probably dates back to the invention of the roulette wheel. Computer simulations have demonstrated that the Labouchere system wins more than 95 percent of the time but, during the remaining 5 percent of the time, loses more than the accumulated wins, which proves that it cannot overcome the house advantage.

However, two methods constitute a very real risk to casinos. Modern casinos use electronic sensors and computers to monitor their roulette wheels for any discrepancies in the expected probabilities and replace them long before they become worn enough to affect their profits.

The other method involves timing the rotations of the wheel and ball once they are set in motion, after which a microcomputer is used to calculate the section of the wheel the ball is likely to land in. Practical experiments in the late s showed that a team of players can enjoy an advantage of 30 percent or more against the casino in this fashion, though only after considerable practice. Similarly, computers have been used by players in casinos to keep track of cards already dealt in blackjack.

Computers as betting aids were outlawed in Nevada casinos in , and all casinos now have regulations against their use, although teams of players using electronic equipment continue to be exposed from time to time.

If you are betting on black versus red or odd versus even, then try the following strategy: This is called the Martingale Strategy. Continue doing this until the wheel lands on red which it inevitably will , to win your losses back and gain a profit. Start off by betting the minimum amount that your table allows. Remember that some tables have a maximum amount you can bet, meaning you may reach the maximum before you see a win.

This strategy requires that you have enough money to be able to afford doubling up each time. Try the Grand Martingale Strategy. This betting system is the same as the Martingale Strategy, but instead of doubling up, the player doubles up and adds another unit.

The "unit" is whatever bet you started off with. Use the James Bond Roulette Strategy. This increases your likelihood of winning by spreading out your bets. Look for the en prison rule.

Look for common ball drop points on your wheel. This means that the ball drops at certain points into a numbered slot routinely. All you can do is watch the wheel over time to notice this. Look for deformed ball tracks. If it is the track that is deformed, no matter what ball is used, you will find the ball usually rattles at the same part of the ball track.

By listening for the rattle and noting where a rattle occurs, you can detect deformed ball tracks and likely common drop points in less time.
