Seemingly, the purpose of this game is to chase down and catch a rabbit. Now this rabbit is an elusive little devil - it can hop randomly in any direction. You can run at least as fast as the rabbit, maybe even faster (the computer will decide). You must get within 20 units of the rabbit to be able to catch him.
