@Ana1234 - I'd much rather have adults playing it than kids to be honest. I used it a couple of times at a play-group I was hosting and it was incredibly annoying because if any of the children was feuding with any of the others they would start complaining any time they were on the board together. "So-and-so is touching me!"
I always wanted to say, of course she's touching you! You're playing Twister!
I actually thought it had been invented in the 80's though. It does seem quite risque for adults in the 60's although I can see kids being encouraged to play it back then.
