Cops and Robbers
Applet demo
This applet is an example of a simple cops and robbers game on a graph. To begin, click the mouse anywhere in the applet window to give it focus. You are the cop (cyan) chasing the robber (red). Use the keys I-J-K-M to move up, left, right, or down, respectively, or O or N to move along the diagonal edge in the center.
