Explo Cube is short for "Exploding Cube". Each of the six faces is spring loaded. You can turn each face one quarter turn left or right like a regular Rubik's Cube
. However, once you turn a face a half turn from its starting state, the face will blow off. The center is unlocked from the core and a strong spring launches it outward, taking edges and corners with it. Technically, this puzzle is a variation to Tom van der Zanden's Constrained Cube
, with the difference that an illegal move is not blocked, but results in an exploding puzzle. Also, the constraints are not indicated at the outside, which makes this puzzle well suited for some prank, a bit similar to Fall Apart Cube
, but with a more spectacular result.
