Sonic Swing

The Sonic Swing is an obstacle, firstly introduced as the first obstacle on every season of Team Ninja Warrior (including American Ninja Warrior: Ninja vs. Ninja).

Competitors have to run full speed across four angled steps (which increase in height), arranged in a straight line, and then grab the rope to swing to the platform (in a similar fashion with the Sonic Curve, except the steps were not positioned in a curve). Then, they must grab another rope to swing to the next platform to advance.

Since Team Ninja Warrior is a competition where competitors compete each other in a side-to-side course, several competitors made a mental mistake by grabbing the rope too low and having not enough momentum to swing to the platform.

On American Ninja Warrior: Ninja vs. Ninja, with modifications all throughout the course, during the individual races (the first 3 heats), competitors would run in a longer distance, having to run the runway before attempting the obstacle. However, during the relay races (the last 2 heats), the first competitor from each team would start in the same distance as the previous Team Ninja Warrior seasons.

American Ninja Warrior Junior
The Sonic Swing appeared as the first obstacle in the 9-10 and 11-12 age groups. The obstacle was relatively easy, as only two competitors failed it: Luke Milman and Peyton Sherrill. However, a handful of competitors failed to get enough momentum on the ropes, and had to make multiple swings to make it from platform to platform. Some competitors spent less time on the obstacle by not using the ropes at all, opting to push them away as they jumped from platform to platform.

Ninja Warrior Poland
At Ninja Warrior Poland 2, the Sonic Swing obstacle appeared as the first obstacle in the semi-finals and finals' Stage Two. It eliminated the average number of participants. Unlike American Ninja Warrior: Ninja vs. The obstacle ninja consisted of only one rope and a landing platform that ended the obstacle. At Ninja Warrior Poland 3, the obstacle reappeared as the first obstacle in the semi-finals and finals' Stage Two.

At Ninja Warrior Poland 4, the obstacle appeared first during the Heats. It was the first Stage One obstacle in the finals with a Giant Cycle instead of a rope. At Ninja Warrior Poland 5, a slightly modified Sonic Swing reappeared as the first obstacle during heats. This time the competitors had to grab a suspended trapeze (similar to those used in Up for Grabs) instead of a rope and use it to get to the landing platform. In the finals Stage One the trapeze was replaced with a Cargo Crossing obstacle net.
