Pionir Box

a.k.a. Pionir Cube
Made by Artex, Hungary, 1984.
(plastic, 2 inches)

A total of 67 balls can be moved along tracks one the inside edges of the box by tilting the box (e.g., in a fashion similar to the Varikon 3x3x3 Box); Varikon 3x3x3 Box); there are 7 balls on each edge (with the corner balls being shared between three edges), where one ball is missing. Each side of the box has a paper label with four colored dots on it. All the balls are black, except for 4 red, 4 green, and 4 yellow balls, which in the solved position, must be located in the middle of edges next to the same colored dot on the labels. Jaap's Page presents a solution.
