A world of relentless game! Is their choice the loyalty they have been with? Is it the power of the team? The eleventh challenge "Washing the laundry". Each village selects two representative residents to prepare laundry, and the remaining residents participate in a formula puzzle. Residents who are making laundry move the water from the common tank to the team tank by repeatedly moistening and wringing towels. When the water in the team tank is full, retrieve the wooden cube, check the password, and deliver it aloud to the rest of the residents. Residents who participate in the equation puzzle open the box containing the equation puzzle board and number tiles with the received password and match the puzzle so that the equation is established. The villager who completes the puzzle raises the flag and checks whether the answer is correct, and the team where all villagers complete the formula puzzle first wins. Faster! More precisely! Don't spill a single drop of water! And make the perfect formula! A head-to-head match between the body and brain areas of each village unfolds! The last chance to prove your skills ahead of the final TOP3 decision! Who will be the dropouts who will not be able to join the finals on the last night in the circular village? (Source: TVING)
