The first type of skewb cube you can buy is a magnetic one. A good magnetic skewb, on Amazon, cost $10.99. You would want a magnetic one because they are fast and just when you move the pieces it has a good feel ( if I were you I would get that one ). The second type of skewb you can get is a speed skewb. On Amazon, this would cost $6.95. ( if I were you, I would think the non magnetic cube is a better deal.)
There are two different types of pieces on the skewb cube. The first piece is the center. As you can guess the center in the piece located in the center of the face. There are six centers on the cube. The second piece is the corner piece. The corner piece has three colors and has four on each side, 8 on the entire cube.
This cube is pretty easy to solve. It moves pretty weirdly like the ivy. It has 3 steps 1 algorithm. That algorithm has only four moves to it. The first step is to solve the white side plus the first layer. The second step is to put all the centers in the correct places. The last step is to solve the entire cube. The algorithm is R, L', R', L
