Name Of A Tv Quiz Show.

[searchlight]

Was there a quiz show where in the final round the contestant had to light up squares then run back and press a plunger to see how many correct answers had been lit up. Against the clock and a certain score needed to win.
Any help welcome thanks.

There was a similar format in this week's 'Question of Sport' on BBC1. One of the competitions was where the team captain had to choose 5 Cup Final winners from a grid of 9 squares. Well, I think it was 9 squares. There was a lot of to-ing and fro-ing between the plunger and the board.
