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 a bit over 4" in length and stays in one piece.  The blocks are deeply and permanently laser engraved.  They  turn on a strong nylon bungee cord.  The 7 block model here has over 4000 permutations.  We believe there is 1 correct solution, though that is not verified yet.

There is also a 9 block Alpha snake available.  It is much more difficult, with over 64,000 possible permutations of the snake.
