Made in the Czech Republic 1983.
(box and six 1.2 inch plastic cubes)
Each of the six cubes has a different one of the colors
red, blue, green, yellow, white, and black on each side.
This puzzle is similar to
Drives You Crazy,
but with a different color pattern.
Like the four block
the object is to arrange the cubes in a line so that each side has no duplicate colors.
Here is a solution and its corresponding graph
(constructed the same way as for Instant Insanity):
cycle 1: Y - 1 - B - 2 - G - 3 - W - 4 - BK - 5 - R - 6 - Y
cycle 2: Y - 4 - G - 5 - B - 6 - W - 1 - R - 3 - BK - 2 - Y
