It’s a 3D triangle; a pyramid.
Or in technical terms, it’s a Shengshou Triangular Puramid-Shaped Cube; that’s what it said on the box anyway. Less sides; it shouldn’t be as hard to solve as a cube, right? Not only that, it comes with directions! I quote: 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. Hey, what could be easier than that; especially step 2? I’ll report back.
