Subway Shuffle

The iPhone game Subway Shuffle is a collection of puzzles set in a subway system. You have boarded a car on the Red Line, and your task is to reach your destination. The problem is, there are other subway cars in your way! Each subway car can move only on its own color line: the red cars on the Red Line, the blue cars on the Blue Line, etc. Can you shuffle the cars from station to station, eventually moving your own car to your exit station? Subway Shuffle comes with 70 different layouts, of increasing difficulty. The early levels are fairly easy. They help you learn the techniques you will need to solve the later levels -- which, though simple looking, are surprisingly challenging.
