In this competition, the only one of its kind in France, eight pairs of participants wage a fierce battle. In themed challenges that can last for hours, they are called upon to erect impressive structures using modular plastic bricks. At the end of each challenge, host Eric Antoine, accompanied by two Brickmasters - experts in this discipline - evaluate the competitors' achievements on two aspects: their artistic skill and their technical mastery. At the end of the eight-challenge competition, the winning team receives a cheque for 20,000 euros.
