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.
Another interesting property is that
any AxBxC cube can be simulated by selectively turning
the Revenge cube. A, B, and C can be any number between
1 and 4.
1: Don't turn along any of the slices in that
direction.
2: Turn along the center cut only.
3:
Turn the outer two cuts only.
4: Turn all three
cuts.
If you don't own a Rubik's Domino (2x2x3) you
can use a Revenge cube as a substitute.
