Roulette is played using a shallow, lipped bowl enclosing a revolving wheel, which has numbered slots alternatively colored red and black. A steel, nylon or ivory ball is thrown into the revolving wheel and lodges in a slot when the wheel slows.
There is also a baize betting board (or layout) and colored chips of nominal values used for placing bets on the board. Bets can be made on single or combinations of numbers, or on red or black.
Players bet against the bank (or house), which offers odds that vary according to the type of bet – for example, long odds (35-1) on single numbers; short odds (even money) on red.
Players place their bets and the banker then spins the wheel. Once the ball has dropped no further bets may be placed and no bet can be altered. The slot in which the ball lodges marks the winning number and color.
Odds paid by the bank
The wheel’s 37 slots are numbered 1 to 36 (alternately red and black), plus a 0 (zero) slot which is green. Odds paid by the bank are:
On any single number including the zero – 35-1.
On the line between two numbers, when either number comes up 17-1.
At the end of a row of three numbers (for example,31,32 and 33) when any of the three numbers comes up – 11-1
On the intersection of four numbers when any of them comes up – 8-1.
At the end of the line horizontally separating the 0 and the numbers 1,2 and 3 (a four number combination) – 8-1.
At the end of the line horizontally separating two rows of three numbers ( a six number combination) 5-1.
At the bottom of a vertical column of 12 numbers or on the ‘dozens’ (1-12, 13-24, or 25-36) – 2-1.
Evens are paid on high numbers (19-36), low numbers (1-18), odd numbers, even numbers, black or red.
When the o (zero) comes up, the bank pays off for bets placed on it and on combination bets between it and any adjacent number or numbers. The bank takes all other chips, except those placed at evens. On these it returns half the stake.
Rules differ slightly through the world for example American roulette has a double zero in addition to the zero.
