I find the wikipedia definition to reflect my perception of what is casual:
A casual game is a video game or online game targeted at or used by a mass audience of casual gamers. Casual games can have any type of gameplay, and fit in any genre. They are typically distinguished by their simple rules and lack of commitment required in contrast to more complex hardcore games.
Most of the games in your list have very simple rules and arent particularly emotionally or intellectually engaging (lack of commitment). So I think most are casual.
