Follow up to the Rubik's cube, as shown by its name.
Produced in 1982 and 1983 by Ideal in Taiwan and Macau.
This puzzle is a far more daunting challenge than the 3x3x3 cube. The number of pieces is far greater, and there are no "fixed" pieces to serve as a reference. This puzzle didn't sell very well, partly because the market was saturated by the 3x3x3 cubes (Ideal and others) and because many were so frustrated with the original cube that they wanted nothing to do with a more complex puzzle.
This puzzle has an ingenious mechanism, with elements similar to both the 2x2x2 and 3x3x3 cubes. At the center is a sphere with three perpindicular grooves for the center tiles to slide in. A set of specially shaped blocks prevents the sphere from becoming misaligned with the rest of the cube. There are two edge pieces at each face intersection. The corner tiles are similar to their 3x3x3 counterparts.
This puzzle (in its original form at least) was somewhat fragile, so if you own one be careful with it.
