Mobile games are applications that allow people to play a game on a mobile handset. The main categories of mobile games include Puzzle/Strategy, Retro/Arcade, Action/Adventure, Card/Casino, Trivia/Word, Sports/Racing, given in approximate order of their popularity.^[3]

Several studies have shown that the majority of mobile games are bought and played by women. Sixty-five percent of mobile game revenue is driven by female wireless subscribers. They are the biggest driver of revenue for the Puzzle/Strategy category; comprising 72 percent of the total share of revenue, while men made up 28 percent (see Table 2). Women dominate revenue generation for all mobile game categories, with the exception of Action/Adventure mobile games, in which men drive 60 percent of the revenue for that category.^[4] It's also said that teens are three times as likely as those over twenty to play cell phone games.^[5]
