Cannonball (キャノンボール) was originally the sixth obstacle in the First Marine Stage in the first two tournaments, but with the introduction of Alphabet Parley and Island Escape, it was placed the seventh obstacle in VIKING 3. In VIKING 4, it would again change position as the fourth obstacle in Third Fantasy Stage.

It consisted of four spheres suspended in the air, each with a diameter of 90 cm. The length of this obstacle was 5.4 metres. Competitor had to run across the spheres, which spun when touched. Moving too slow on the spheres resulted in many slipping and tumbling down into the water. SASUKE All-Star Yamada Katsumi failed on this obstacle in VIKING 2, as he made it to the third sphere before slipping, however he caught himself on the ropes suspending the last one before finally falling.


TERU attempting Cannonball in VIKING 4

In VIKING 4, as the course was designed to be a head-to-head tournament, two sets of Cannonball were provided. As with the Main Deck in the First Marine Stage of the same tournament, the competitors could attempt any of the sets provided.

A variant of the obstacle, the Spin Bridge, would later be used in SASUKE 27, with the only true difference being thicker support ropes and a more even pattern, albeit SASUKE 28 would use a pattern closer to the VIKING version. Later, the Spin Bridge (mostly called as the Spinning Bridge) would be used on several SASUKE/Ninja Warrior's international formats (e.g. American Ninja Warrior, Ninja Warrior UK, SASUKE Vietnam, and SASUKE Ninja Warrior Indonesia), albeit several modifications had been made to make the obstacle harder than the one used in both VIKING and SASUKE.
