Magic Cube Pyramid Instructions

My "Rubik's Tetrahedron" is actually called a "Magic Cube Pyramid" (by Fanxin), which doesn't seem right since a pyramid has a square base, and of course a cube has six square sides, but my toy has four triangle sides. On the box it notes that "The difficulty:" is three stars out of five, and also this mysterious phrase: "Match Special-purpose." The instructions, which are in Chinese characters that I can't read and English, are even more enlightening:

Angle block on the base block rotate freely, in the reduction process angle block does not play any role, can be neglected.

1. Rotate cube, make the 3 blocks of red face in a plane:

2. Make the red edge block in the plane, this is very easy, try to understand;

3. Cube from another direction, to turn without the red base block into the next diagram;

4. General at this time there are three edge blocks direction or the wrong place, sometimes two. Then you can swap any red-faced edge blocks as the switching point, and dislocation edge blocks, perhaps to swap a few times, you can restore. You can restore.

Congratulations!

Famous Hat here again. Doesn't that explain everything?
