This is one of my favourite puzzles, I learned to solve this one around the same time I learned to solve the Rubik's cube. It must have when I was 13 or 14. I'm still able to solve this puzzle and I was able to solve the cube until a few years ago. But I think dementia has crept in 'cause I have forgotten how to solve Rubik's cube.
I have this game in a few versions. One of them was made by my father.
