In the race world sequences Kerwhizzitor commentates. Kerwhizzitor (Jacob Scipio) moderates the quiz, asks the questions, makes bad puns and rhymes and tries to keep the teams in order.
All of the teams are likely to encounter unexpected setbacks and opportunities along the way, making the outcome of each race unpredictable. Each race world is a themed environment (the questions usually include clues to the theme) containing three, or occasionally four, zones, and each race comprises two laps (except in 'The Deserted Desert Dash', which is a novelty race with no set route and a hidden finish line). The pods are then raised through the roof of the studio into the CGI race world. Once the question rounds are complete, the teams' pods are assembled around them and the respective mods are installed.
All of the questions are multiple-choice, with the answers colour-coded red, green, yellow or blue (not coincidentally, these are the standard colours of the function buttons on TV remote controls).
