Missing Marble

I got this fun puzzle for Christmas. It is interesting because it has no visual component. A marble is embedded in a block with an internal maze. The challenge is to tilt the block around until the marble comes out. What I found unusual was the experience of gradually forming a mental map of the maze, by listening to, and feeling, the steel ball clicking around inside the obscured wooden maze. I still remember the moment I got a clear picture of how the maze was shaped, and as soon as that happened, I could get the marble out every time.
