CAST A.B.C

As you can see, the letters A, B and C. The key word to keep in mind here is "tracks". In this puzzle you are trying to free the 'C' from the 'AB' piece. Taking thewrong route will lead to a dead end, so to speak. Based on a puzzle that came out back in 1911 in England, this puzzle has a lot of history behind it. I recommend this one for beginners who want to get started with puzzles.
