Game show format from Fremantle. Contestants answer general knowledge questions to win giant shapes worth real cash, then use an enormous claw to build an increasingly teetering tower. But they never know which of the 30+ shapes is coming next - a circle, a teddy bear, a top hat - the sheer variety makes stacking increasingly challenging as the tower rises. As the money grows, so does the tower, creating can’t-look-away suspense as every new shape leaves one question hanging in the balance: will it stay or will it fall? (source: fremantle.com).
