From the web site:
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?

But it has zero visibility, because it is not listed among Apple's favorites, best of puzzles, etc. However, that evening Apple finally posted the free, "lite" version of Subway Shuffle (8 days after I submitted it). The next day I sold 44 SS (9000+ free downloads); yesterday I sold 66 SS (7500+ free downloads). Well, I like the trend, anyway.
