The Prism See-Saw (プリズムシーソー), known as the Prism Tilt on English broadcasts, was an obstacle introduced in SASUKE 13's First Stage as the first obstacle, replacing the Yamagoe. Competitors needed to jump over a small pit onto a large triangle which was supported by an axis in its center. The addition of weight on one side of the triangle would tilt it into the water, so it needed to be crossed quickly. This obstacle required both speed and balance. While it eliminated a fair amount of competitors, it was replaced in the following tournament with the Ensuitobi.
The obstacle reappeared in KUNOICHI 6 as the second obstacle of the First Stage, known as the Sankakku Bashi.
The obstacle re-reappeared in American Ninja Warrior 5 as the third obstacle in the Baltimore qualifying round.
