The Parley (パーレイ) was the fifth obstacle in the First Marine Stage in the first two VIKING tournaments and the sixth in VIKING 3. It was composed of an addition problem created at random by two buttons prior to approaching the obstacle. The competitor stands on a trapdoor with the problem and a number pad in front of them and must type in their answer after solving it. Answering correctly would open the sword barrier on the other side, letting them continue. Answering incorrectly would result it the trapdoor opening, dropping the competitor in the water. While the addition problems were relatively easy, the timer made many people rush which resulted many failures. This was especially noted in the 3rd VIKING competition, as the obstacle shockingly took out Nagano Makoto who had made it to Final Viking in the previous tournament.
