Snake cube

This is made of wood. It’s a type of brain teaser that you form into a cube from a snake form. A friend of mine bought this puzzle and was able to solve it for almost a day. She brought it home to let her niece and nephews solve the puzzle. To her surprise her 9-year-old nephew (who loves puzzle by the way) was able to solve it within 15 minutes. Wow! And of course all her ate’s and kuya’s were so surprised. They returned the cube into its snake form and let their cousin solve it again. Of course, he wasn’t able to memorize the steps in solving the puzzle but after careful analysis within 30 minutes he was able to solve it again. Whew!
