The teams land in Lisbon to take on the Dark Destroyer and the Sinnerman, who have set a series of quiz questions that the teams must solve to navigate across the city and find Bradley Walsh at the finish line. The final pair will need to beat them to join the other teams and head onto the next city, lose and it's the first flight home.

The teams arrive in Zurich, where the Governess and Dark Destroyer challenge them with quizzes guiding their race to Bradley Walsh. Starting on Lake Zurich, they tackle Einstein-themed games, visit the FIFA Museum and a chocolate factory, then head into the Alps for a cable-car quiz and James Bond villain's lair.
