Roulette is one of the world’s favorite casino games for good reason: its high level of mystery and excitement makes it great fun for both novice and veteran players alike.

Roulette wheel features numbered slots alternating between red and black slots, plus either a single or double zero depending on the game being played, with pockets grouped either into “dozens,” which consist of three numbers arranged in groups, or on its exterior surface which covers numbers 1-36 as well as any other areas on the table. You can bet on individual digits or groups of numbers (known as outside bets); your dealer will ask you to designate chips before marking them with colors to indicate their values – it is often best practice to separate bets between spouses and friends so as to prevent confusion!
