As far as I know ITC (Idéal Loisirs in France, Arxon in Germany) released a good quality Rubik's Cube as a game.
This edition is known as Rubik's Game in USA, Rubik's Challenge in UK (both distributed by ITC), Rubik's Mühle in Germany (distributed by Arxon) and Le Jeu Rubik's Spécial (distributed by Idéal Loisirs France).

I finally got the German boxed edition today.

Are there other known editions? Dutch f.i., as Arxon was distributing 3x3 and 4x4 cubes in The Nethgerlands and in Germany.
Are there Scandinavian, Italian, Spanish editions of this game?

In the ads from 1982, the French edition shows the pegs with different colours, all cubes I have seen so far had white pegs.
The same goes for German ads where the pegs were transparent with coloured tops.

Can anyone confirm that these coloured pegs exist/ed?

My sample has white pegs (and without box)
Can you upload additional images showing each box on its own?

Thank you
Andreas
