The global gambling market can be divided into online gambling and off-line gambling. Online gambling which is only 10 years old is predominately done over the Internet, but it also includes gambling via mobile phones and interactive TV. Off-line gambling means gambling in a physical location, e.g. a casino. Gambling can be divided into Games of Skill (Sports betting, Horse racing, Poker, etc.) in which the customer can benefit from having a certain degree of knowledge and Games of Chance (Roulette, Black Jack, Slot machines, Lotto, Bingo, etc.).
