You visit a carnival, and see a certain attraction, being promoted by a clown:

"Roll up! Roll up! See the amazing tyrannosaurus rex, king of the dinosaurs in his lair! Perfectly preserved in silicon since prehistoric times, he is brought to you for your entertainment and exhilaration! If you dare to enter his lair, you do so at your own risk! The management accept no responsibility for the health and safety for the adventurer who enters his realm! The management advise that this is not a game for those of a nervous disposition!"

You decide to enter the T-rex's maze, with the goal of escaping to claim a prize (we're not going to tell you what it is, so you've have to enter the maze and escape to find out!)...
