Snaak | Classic 3D Cube Puzzle and Creative Design Challenge Toy for adults and teens an engaging, un-putdownable classic twistable buildable design challenge, Snaak is a line of 64 interlocking cuboid units that transform into infinite complex geometries and spatial constructions each Snaak cube unit can move in any of five directions relative to the preceding unit there are up to FIVE TO THE POWER OF 63 possible snaak configurations... that’s roughly TEN TO THE POWER OF 44. That’s 1000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 possible snaak configurations! ...more snaak configurations than atoms in universe! AND if you’re not excited by that mindbending fact, try this one… there are estimated to be TEN TO THE POWER OF 82 atoms in the known observable universe... so with just TWO snaaks you can construct more configurations than there are atoms in the universe!! Snaak is inspired by the awesome superperfect number 64. The number sixty-four is the first whole number that is both a perfect square and a perfect cube. It makes 8 units by 8 units square, which is the iconic chess board. It makes the 4 x 4 x 4 units cube. It makes a hollow 4 x 4 x 4 cube with a 2 x 2 x 2 cube. It makes the eight cubes in a row and the eight diamonds. It makes tesseract, octahedron, dodecahedron, hexadecagon... truly infininty in your hands. More combinations than atoms in the universe!!!
