Rotate the blocks such that the letter A thu I show up on each side of the snake.  No letter can be repeated on a side. A unique Creative Crafthouse designed puzzle with Alpha logic by Ken Irvine of New Jersey.

The snake is about 5 1/2"" in length and stays in one piece.  The blocks are deeply and permanently laser engraved.  They  turn on a strong nylon bungee cord.  The 9 block model here has over 64,000 permutations.  We believe there is 1 correct solution, though that is not verified yet.

There is also a 7 block Alpha snake available.  It is less difficult, but not easy with over 4,000 possible permutations of the snake.
