The Spin Bridge (スピンブリッジ) is an obstacle used in SASUKE 27 in the First Stage, positioned after the Soritatsu Kabe. The obstacle is a version of the Cannonball, which was used in VIKING tournaments, where the competitors has to run across four spheres, which would spin when they stepped on them. The obstacle did small damage for its debut, eliminating previous finalists, including SASUKE All-Star Yamamoto Shingo and veteran Takahashi Kenji. It should also be noted that this obstacle is infamous for dislocating Kanno Hitoshi's shoulder and forcing him to withdraw after the Slider Drop in the Second Stage. In SASUKE 28, it returned and was placed in the third position, just after the Rolling Escargot. It was proven to be much more brutal than in SASUKE 27, as it took out numerous competitors, including SASUKE 24 finalists: Lee En-Chih and Hashimoto Kōji, and two SASUKE All-Stars: Yamamoto Shingo (for the second straight tournament) and Akiyama Kazuhiko. Gondou Hiroyuki was the first to beat the obstacle in that tournament. It was replaced by the Hedgehog in SASUKE 29.
