Rotate the blocks such that the letter A through 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.

Adam K. ★★★★★

My son loves logic puzzles, and this one kept him busy for a solid hour trying to get all nine letters on each side without repeats. The rotating wooden blocks have a nice smooth feel when you twist them.

Alexander ★★★★★

I was a little worried the letter blocks would be too small for my 12-year-old, but they're actually a perfect size to rotate and test combinations. The logic of getting A through I on each side without repeats is a great challenge that kept her focused for a solid 20 minutes. She's already asking t

Alexander ★★★★☆

The rotating blocks are satisfyingly chunky and the puzzle feels well-made. My tween figured it out in about 20 minutes, so it might be too easy for older kids. Still, it's a fun mental break from screens.
