Plot synopsis: In this original show, 50 contestants from all over France compete in a series of questions that really put their brains to the test. But only one of them will make it to the “Final Circle” and win up to 50,000 euros! In a spectacular 360-degree setting, the contestants sit in a circle around Arthur. There are a total of 6 circles, each corresponding to a level of difficulty. In each circle, the contestants compete in 6 categories that require them to use every ounce of their brainpower: visual memory, language, logical reasoning, memory, math, and spatial reasoning. Only the best earn the right to move on to the next circle. The further the contestants advance through the circles, the harder the questions become and the tougher the competition gets! Until the final circle, where only one contestant can win the 50,000 euros!
