The first step is solving the white side and the first layer. That is like the 3 by 3. Then, you have to put in the edges of the second layer. Next, you have to make "bunny ears" which are 2 edges and a corner. (do that on every side) Next, finish the first half of the cube. (6 sides: white, and the colors surrounding it) Then, you do the corners of the next layer. Then you make the gray star and position the edges. Next, you position the corners. Lastly, you twist the last corners.

A good speed cube and stickerless megaminx is $11.99 on Amazon. A magnetic megaminx on Amazon is $26.99. You would want a magnetic one because it moves really quickly, isn't loose and has a good feel. If you are really into cubing you could get a magnetic one but you probably shouldn't.
