Jimmy Tarbuck (Lisa's Dad) hosted this gameshow, where contestants used to bet their points on the multipe choice questions. The four possible answers would be in evens (1-1), 2-1, 3-1, 5-1, 10-1. Depending on whether you chose the right answer and which odds slot it fell into depended on how many points you had back. Most of the contestants were not that bright so guessed a lot of the time, often getting them down to zero, which meant they couldn't bet on the next question.
Four different contestants would compete each week, with two elimination rounds and then a grand final. I can't remember what the prizes were, so they couldnt have been too bad (like Bullseye).
