Casual games refers to a category of software-based entertainment that includes word and puzzle games, board games, and even some classic arcade titles. While not new, the casual-games industry is enjoying a renaissance driven by advertising dollars and the use of mobile devices. Because casual games tend to be small and have minimal processing needs, they're ideal for cell phones.
