YJ Cube - Ruilong Skewb 3 x 3 x 3 Cube

At first glance, this is a twist puzzle similar to the standard 3x3 cube. However, instead of each face being split into smaller squares, there's a diagonally-oriented square section in the centre of each face and four triangles. Although cubical in shape, the Skewb differs from a standard 3x3 in that its axes of rotation pass through the corners of the cube rather than the centres of the faces. Solving the puzzle still involves restoring each face to a single colour, but some of the in-between states don't quite look like a cube! This is a challenging puzzle and lots of fun to solve.
