CoolmathGames is part of the Coolmath Network of websites, which also includes Coolmath4Kids and Coolmath (their first website). While Coolmath4Kids is intended for kids 12 and under, CoolmathGames is designed for people of all ages. Due to its wider intended audience, CoolmathGames includes a much wider variety of games, including daily games. It allows users to create playlists of their favorite games when logging in. Like the rest of the Network, CoolmathGames is free to use as it is an ad-based service.
