In the German version of the Japanese original show "Sasuke", the candidates have to overcome four obstacle courses. At the start there are initially 100 participants, both hobby athletes and professional athletes, who have to complete the first course over water basins individually and one after the other. Strength, agility and stamina are helpful here, because those who are not fast enough or come into contact with the water are eliminated. For the German audience, a complete run is divided into several shows until the best participant is chosen as the "Ninja Warrior".
