just curious about it. the pieces look like they are from chinese checkers, but the board does not resemble the game.

I thought they were playing Mastermind, but I could be mistaken.
shareIt's certainly 'mastermind'. I was very big in those days, but faded rapidly. It has been re-released in a more modern looking way since. I'm not sure where you live, but here in the UK it's still ubiquitus in charity shops, car boots etc.
Ebay is also awash with them for around £2 -3.00.
