# How to Beat the House Edge in Roulette

Roulette is a casino game that offers glamour, mystery and excitement to players. It is easy enough for beginners to enjoy and can provide a surprising level of depth for serious betters. While the rules are straightforward, there is plenty of room for a betting strategy to improve your odds.

A revolving disc-shaped device with thirty-six compartments or pockets, painted alternately red and black, and marked with one or more of the symbols 0 through 36. The roulette wheel is spun and the ball dropped into one of the pockets to come to rest in a number as indicated by a croupier.

The payout for a winning bet is determined by the location of the number in relation to the other numbers on the layout. For example, a straight bet on number 2 costs 40 chips and pays 392 chips, if it wins. However, the chips that are lost remain in the same place on the table and, in the absence of a request to the contrary, are up for grabs again on the next spin.

A roulette table carries a placard with a description of the minimum and maximum bets allowed. It also shows the number of available chips for each bet. This information is critical to making informed bets. Each player should choose a table within their budget before betting. If a player has won a round, they should cash out their winnings as soon as possible and continue to bet within their predetermined budget.

It is possible to beat the house edge in roulette, but only by using a system that exploits imperfections in the game and the wheel. Various systems have been proposed, some complex and others based on faulty mathematics. The best known of these was developed in the 17th century by Blaise Pascal, a French physicist, philosopher and inventor who was seeking a perpetual motion machine.

The most common method for reducing the house edge is to use the Martingale strategy. This involves increasing your bet size after each loss and reducing it after a win. It works best on outside bets, such as odd/even and high/low. In fact, if you use this strategy in conjunction with a betting system based on the D’Alembert strategy, you can reduce the house edge to just 1.3%. This is significantly lower than the 2.85% advantage of the American version.
