Secondary Interactive Games and Challenges

This is our collection of games specially chosen for use in the computer room or on the whiteboard. Each explores a strategic or mathematical theme; they will work well as teacher-led class activities but are also suitable for students to play directly, as they can all be played by individuals against the computer and none require direct teacher mediation. As with all of our games, players should be armed with a pen and paper to help to plan their strategies and record their findings as they play.

The games are listed in approximate order of difficulty.
