Casual games
Casual games derive their name from their ease of accessibility, simple to understand gameplay and quick to grasp rule sets. Additionally, casual games frequently support the ability to jump in and out of play on demand. Casual games as a format existed long before the term was coined and include video games such as Solitaire or Minesweeper which can commonly be found pre-installed with many versions of the Microsoft Windows operating system.
Examples of genres within this category are hidden object, match three, time management, tetris or many of the tower defense style games. Casual games are generally sold through online retailers such as PopCap, Zylom and GameHouse or provided for free play through web portals such as Newgrounds or AddictingGames.
While casual games are most commonly played on personal computers, cellphones or PDAs, they can also be found on many of the on-line console system download services (e.g., Xbox Live, PlayStation Network, or WiiWare).
