Bob Holness hosted this fondly-remembered quiz show, in which students competed to answer enough questions correctly to complete a run of answers across the board. This was the latest and most sophisticated computer version of the concept.

The exact mechanics of the game have been customized slightly. You start by choosing a question, which are all represented by the first letter of the answer. You must 'buzz in' by pressing your letter to input the answer (don't worry about exact spelling). If you get the question wrong, the computer chooses a square (seemingly with no strategy). In two player games each player has their own buzzer, and a correct answer sees you choose the next question. A digitized version of Bob's face reads out the questions - just be careful if you get any where the answer is 'organism'...
