The CQGs presented here are single-player games. We intend to implement multiplayer versions with options including collaborative games, and online multi-player games. As stated in the introduction, this project is motivated by the continuous need to improve and develop learning and testing tools for use in all learning environments, and in support of interactive engagement. There are several common issues across different ESL environments , and further implementation (as multi-player games) may help address some of the ESL issues.
