The Master Kilominx is made from a high quality black plastic. The idea of this puzzle is to scramble up all 12 sides and then return it so that each face only has one color on it. This puzzle is extra hard because each of the 12 faces has 5 edges, and each edge is 4 pieces across. Also, there is no stationary center piece, so it can be hard to find out where all the colors go. The do-it-yourself feature allows for you to customize your color pattern however you like. The Master Kilominx was invented by David Gugl and is manufactured by MF8. MF8 is owned by Mr. Fok, who is not only a designer, but also owns an OEM factory, which allows him to continually release puzzles into the market.
