The Sankaku Bashi is almost identical to the Prism See-Saw from SASUKE 13. It was the second obstacle of the First Stage in KUNOICHI 6. It is called the Prism Tilt on G4. It is a triangular prism that tilts on an axis in the center as the competitors jump onto it. In KUNOICHI 6, it took out at least four competitors and in SASUKE 13, it took out over 13 competitors. In SASUKE 14, this obstacle was replaced by the Ensuitobi and in KUNOICHI 7, the obstacle was replaced by the deadly Danchigaubou.
