Roulette is a game of chance that uses a roulette wheel and a betting grid. A ball is sent into a numbered wheel in the opposite direction to which the roulette wheel is spinning. The roulette bets are determined by which particular numbered pocket the roulette ball lands in. In online roulette, the wheel and the ball are virtual, but the game and the payouts are real.

The roulette wheel has little pockets around its perimeter. The pockets are numbered from 0 to 36. (In American roulette, there is an additional 00 pocket.) Each pocket is red or black, except for the 0 and 00 pockets, which are green.

The roulette wheel is spun in one direction, and a little ball is spent spinning around inside the wheel in the opposite direction. Eventually, as the roulette wheel slows down, the ball comes to rest in one of the little numbered pockets. That is the winning roulette number! You win at roulette if you bet on that number or on a group that includes the winning number

There are many types of roulette bets. That is part of what makes the game so interesting. Before getting into specifics, the general rule to keep in mind when playing roulette, is that the more numbers you bet on, the higher your probability of winning at roulette, but the lower the payout. Conversely, if you bet on fewer numbers, you have a lower probability of winning, but a higher payout if you do.

For example, if you bet on a single number, you can win a jackpot of $350 on a $10 bet if you win, but you are not likely to win very often. If you bet on all the red numbers, you have a good chance to win pretty regularly, but you'll get only a $10 payout on your $10 bet.

The roulette table features a betting grid, in which all the roulette numbers are laid out in three vertical columns and twelve horizontal rows. You place your roulette bet by placing your chips — or, if you are playing roulette online, clicking your mouse — on the appropriate area of the roulette table.

There are two main types of bets: Inside Bets and Outside Bets. Inside Bets are placed inside the betting grid on the roulette table and pay out higher odds. Outside Bets are bets that are placed outside of the betting grid; they incorporate larger groups of numbers so the odds are naturally lower. You may place more than one bet in the same game of roulette.

Following is a list of the different types of online roulette bets, with instructions on how to place the bet and the payout if you win the bet:

Inside Bets

• Straight Up Bet — A straight-up bet pays out the highest odds. It is a bet on a single number only. To signify the bet, the chip is placed in the centre of the square of that number. A straight-up bet pays out 35:1.
• Split Bet — A bet on two numbers that are adjacent to each other on the betting grid, either horizontally or vertically. The chip is placed on the line between the two numbers. The payout is 17:1.
• Street Bet — A bet on three numbers in a horizontal row. The payout is 11:1.
• Corner Bet (also known as Square Bet) — A bet on a block of four numbers on the grid. The chip is placed at the middle corner where the four squares meet. The payout is 8:1.
• Five Number Bet — This bet is available in American Roulette only. It is a bet on five numbers that are made up of 00, 0, 1, 2 and 3. To signify this bet, the chip is placed on the line between the 0 and 1. This bet pays out 6:1.
• Line Bet — A bet on six numbers that are in two adjacent rows of three. The chip is placed on the line above the "Dozen bet" and it rests between the two rows that you are betting on. The payout is 5:1.

Outside Bets

• Column Bet — This is a bet placed on one of the three vertical columns of 12 numbers. It pays out odds of 2:1.
• Dozen Bet — This is a bet on the first dozen (numbers 1-12), second dozen (13-24), or third dozen (25-36). It pays out 2:1
• Even-Money Bet — This is a general term for the even/odd bets, the high/low bets, and the colour bets.
• Even/Odd Bets — These are bets on either all the even numbers or all the odd numbers. They pay out 1:1.
• High/Low Bets — These are bets on all the low numbers 1-18, or on all the high numbers 19-36. They pay out 1:1.
• Colour Bets — These are bets on all the red numbers or on all the black numbers. They pay out 1:1.

All Slots Online Casino offers a variety of online roulette games. The general rules of how to play roulette, as described above, apply to all the roulette games with only minor variations between the different games.

American Roulette is the only online roulette game that has both a single 0 and a double 00 on the roulette wheel.

European Roulette and European Roulette Gold are played with single-zero roulette wheels. In addition to the regular roulette bets described above, they allow special roulette bets called Call Bets and Neighbour Bets.

French Roulette and French Roulette Gold also have single-zero roulette wheels and also have Call Bets and Neighbour Bets. These games also have a special rule called La Partage. Under this rule, if you make an even-money bet and the roulette ball lands on 0, you lose only half your bet instead of your entire bet.

Multi-Wheel European Roulette Gold allows you to spin up to eight online roulette wheels at once. More roulette wheels means more chances to win.

Premier Roulette is European Roulette with the most advanced graphics and special features.

Roulette Royale is online roulette with a progressive jackpot that is constantly growing and can be worth hundreds of thousands of dollars, pounds, Euros, or kroners. If the same number hits five times in a row, you win the progressive roulette jackpot.

Roulette has long been considered the king of casino games. That is because it carries an aura of elegance and sophistication. Now that roulette is available in the online casino — and in the mobile casino too — there is no reason for anyone to miss out on enjoying this legendary game.
