Three-way Free-way

Description

How it works: This puzzle has two parts, a small oddly shaped piece and a board with three shapes: a circle, a triangle, and a square cut into it.  The player is to take the small piece and pass it through all three openings with the piece properly oriented to exactly match the shape it is passing through.

Story behind the puzzle:  This puzzle was shown to me by my Grandpa Free who had seen it in a magazine.  I had made a couple out of wood in previous years, and as I considered what puzzles might be suitable for children, this one came to mind.  I wanted to honor my grandfather, hence the the unusual name!
