The Adventure Game.
Wow. From the very opening, the memories came flooding back. I've watched up to the 3rd series so far and I can say is that what I actually remembered was more or less intact ... if spread over the entire life of the show! Janet Fielding among the plucky 'time travellers' in the one I stopped at. A mixture of The Krypton Factor and Heinz Wolff, the contestants get hints but they have to work it out themselves
... it is a bloody quiz show after all. More to come after I return from my dogsitting duties ahem!!
