Prism See-Saw (プリズムシーソー), called Prism Tilt in English broadcasts, was an obstacle introduced in SASUKE 13's First Stage as the first obstacle, replacing the Yamagoe from the previous tournament.

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. However, despite it eliminated a fair amount of competitors, it was replaced in the following tournament with Ensuitobi.

The idea of traversing a see-saw triangle will then applied on Sankaku Bashi, which used in KUNOICHI 2006 Autumn as the second obstacle of First Stage, also called Prism Tilt during the international rebroadcasts.
