The real trick to roulette is to get lucky, then quit while you're ahead. Every spin has a 1 in 37 (for European) or 1 in 38 (for American) chance of landing in a given pocket.
Some of these numbers include:
17: This number is considered to be the most popular number in roulette, as it is believed to have brought luck to many players in the past. ...
7: Seven is often considered a lucky number in many cultures, and is therefore a popular choice for roulette players.
