The roulette wheels used in the casinos of Paris in the late 1790s had red for the single zero and black for the double zero. To avoid confusion, the color green was selected for the zeros in roulette wheels starting in the 1800s.

If you plan to play online roulette, stick with the bets whose odds almost mirror their payouts. These 'even money' bets include betting on Even, Odd, Low (numbers 1 through 18), High (numbers 19 through 36), Red, or Black. All of these wagers pay out at 1 to 1.

The house edge or vigorish is defined as the casino profit expressed as the percentage of the player's original bet. (In games such as blackjack or Spanish 21 , the final bet may be several times the original bet, if the player double and splits.)

The roulette wheel consists of a solid wooden disk slightly convex in shape. Around its rim are metal partitions known as separators or frets, and the compartments or pockets between these are called canoes by roulette croupiers. Thirty-six of these compartments, painted alternately red and black, are numbered nonconsecutively from 1 to 36. On European-style wheels a 37th compartment, painted green, carries the sign 0, and on American wheels two green compartments on opposite sides of the wheel carry the signs 0 and 00. The wheel, its spindle perfectly balanced, spins smoothly in an almost frictionless manner.

The rainfall all year round is generally reliable and the average for 100 years is close to 640 millimeters per annum. The wettest months in this region are October, January, August and May.

To practice roulette strategy, the key is to bet strategically since the game itself is all chance. One way you can bet strategically is to always double your bet when you lose in a 50-50 chance game. Then, once you win, you'll win all of the money back you've lost. You can also try the strategy where you increase your bet after a win and decrease your bet after a loss. That way if you're on a winning streak, you'll increase your earnings, and if you're on a losing streak, you'll limit your losses.

To calculate odds, start by determining the number of favorable outcomes and the number of unfavorable outcomes. For example, if you're trying to calculate the odds of rolling a 1 on a 6-sided die, the number of favorable outcomes would be 1 and the number of unfavorable outcomes would be 5. Once you know the number of both favorable and unfavorable outcomes, just write them as a ratio or a fraction to express the odds of winning. In the 6-sided die example, the odds would be 1:6 or 1/6.
