Well the 1970s had hundreds upon hundreds of TV game shows, and many of them found their way to the shops a games we could play from home. Many lasted days, but some stood the test of time.
Remember Blankety Blank, well that had a board game and it was just as good as the prizes on the original show with Terry Wogan. It was cheap.
Crosswits a simple form of Scrabble, I think the show use to run in the afternoons in the UK, and the game was rubbish too.
Family Fortunes, now I remember playing this. I think this was the time of the Bob Monkhouse version, but for the life of me I cannot recall how we played that game.
Call My Bluff, this was such fun. To be honest you need not ever had to buy it, just get a dictionary out and do it yourself. But the game had an envelope with the TRUE and BLUFF just like the TV series with Frank Muir.
There were short lived games for The Generation Game, 321, Name That Tune, Catweazle and many other 1970s classic.
