Online roulette is a popular casino game type in which a ball is placed on a spinning wheel. Roulette gamblers can wager on the slot that the ball will ultimately fall into. Each slot is numbered and given a color of either red or black. Several roulette bets have an approximate win chance of 50%, such as even, odd, red, black, 1 - 18 and 19 - 36. Players participating in online roulette casinos can also place more difficult wagers, such as a bet that the ball will fall on a certain number. These types of wagers have larger payout ratios.

Online casino roulette games usually come in a few different variations, including American Roulette, European Roulette and French Roulette. The rule differences between these game types are quite minimal, as they usually only involve the overall number of slots on the wheel or the allocation of a zero or double zero to the wheel.

The best roulette online casinos offer realistic graphics that simulate the look, feel and sounds of a live roulette game. Some cutting-edge online roulette casinos even feature live dealers, which consist of a live video feed of a real dealer accompanied by an interactive roulette interface that can be used for placing wagers. Roulette online casino software is usually available two ways: an Instant Play version that operates from a web browser, and a downloadable casino software package that is installed directly to a computer hard drive. Both options allow for real money online roulette play.

Most casinos that have online roulette games offer several bonuses such as initial deposit bonuses, refer-a-friend bonuses and reload bonuses. Initial deposit roulette bonuses are awarded when you make your first deposit at the online roulette casino site, and usually consist of a 100% or larger bonus with a maximum cash value. Reload bonuses are awarded on subsequent deposits, and are usually smaller than initial deposit roulette bonuses. Refer-a-friend bonuses are awarded to online roulette players that get their friends to sign up for the same online roulette site. These bonuses can be worth $25, $50 or more.

High quality roulette online casinos offer customer support through telephone, email and live chat. Most online roulette casino players prefer live chat, since it allows for fast answers to simple questions without a long waiting period. Our top roulette casinos online also accept a variety of banking methods for real money deposits and withdrawals, such as credit cards, eWallets and bank transfers.
