You can't win in this court. The kangaroo is the judge and you have to bribe it. Supposedly an experiment in "artificial intelligence".
The AI opponent in this HyperCard game is a corrupt judge. The player is the defendant. The goal is for the player to successfully participate in corruption for their own benefit (such as offering a bribe). Get it right and go free, maybe even for free. Get it wrong, go to jail, or get a death sentence.
