Playing Rush Hour

My brother gave me a board game called "Rush Hour". 

The goal of the game is to let the red car out of the box, a midst the traffic jam.
We can clear the road block by moving the car up and down. But no lifting.
It is a fun thinking game.

Towards the end of the game, Timmy changed the rule of the game, whereby the container being the robber and the police needed to chase the robber.  He changed the red car into the black car.
