Mobile games are games that can be played on smartphones or tablets. When the industry first started, iconic games like Tetris and Snake were developed by the mobile phone manufacturers. But today, there are millions of games on offer, created by third-party developers. This has created a whole industry thanks to the emergence of smartphone technology. Mobile games fall under many categories, yet all of them can be classified into two types: single-player mode games and multi-player mode games. This study aims to research the differences between Australian single-player games and multiplayer games in terms of their consumer usage and spending behavior. The study surveyed Australian Android mobile users and conducted paired sample t-test analysis on the collected data. The study has found that despite measuring no statistical difference between players' overall spending behavior, multiplayer gamers spend significantly more time and money playing mobile games than single-player gamers. This suggests that multi-player game players are a more profitable segment of the gaming market than single-player game players.
