Casual Exergames

Just got acquainted with the new term "Casual Exergame" which is a branch of Exergames following these rules:

Easy to learn. Casual games should have limited instructions, provide rules that are easy to learn, and guide players with a clear and consistent user interface.
Simple controls. Casual games should take advantage of assumed knowledge, such as drag, drop and click.
Play in a relatively short play period. Casual games should be able to be enjoyed in a series of short time increments, though sometimes people play one level after another for many hours. Most casual games’ play intervals are between 5 and 15 minutes to complete a level.
Reduced complexity and non-punishing game play. Casual games allow depth and complexity to emerge from the player’s basic actions instead of making the player master a large and complex set of actions.
Family friendly. The IGDA Casual Games SIG deems that casual games should not contain objectionable content, such as overt violence, or sexuality. The CGA agrees that casual games should appeal to people of all ages, genders and nationalities. In recent years, casual games have been developed (e.g., games rated 17+ for Apple’s iPad) that do not adhere to this criterion.
