Pakovalec

a.k.a. Stupid Cylinder
Czech Republic, circa 1990?
(plastic, 1.7 inches diameter by 2.7 inches long)

There are four columns such that when the puzzle is solved, each contains four tiles of the same color (red, green, blue, or yellow). The body can slide up and down and be used to rotate a row (which also rotates some blank tiles that are the same color as the body). The columns are not evenly spaced (two are adjacent and the other two are spaced apart from those and each other); below are some views of a solved puzzle. Jaap's Page gives a solution.
