Girl Playing Video Games

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).
Serious games
Serious games are games that are designed primarily to convey information or a learning experience of some sort to the player. Some serious games may even fail to qualify as a video game in the traditional sense of the term. Also, educational software does not typically fall under this category (e.g., touch typing tutors, language learning, etc.) and the primary distinction would appear to be based on the title's primary goal as well as target age demographics. As with the other categories, this description is more of a guideline than a rule.
