Great Wall

The Great Wall is an obstacle similar to that of the Warped Wall that has appeared in many Roblox Ninja competitions. Based off the sixth obstacle of real-life SASUKE 18, the core concept of the obstacle is that competitors are to run up a slope, jump up, and grab and climb a hanging rope.

First Version (NWoR1-3)
The first version of the Great Wall, appearing from the first to third Ninja Warrior of Roblox competitions, was made up of a series of wedges, followed by a tall window with a four-stud TrussPart connected to its top ledge. Competitors were to run up the slope and jump to the truss, catching it and climbing up to the top. Interestingly, it eliminated four people in its final appearance via falling off the side of the wall, rather than its intended function of causing competitors to run out of time.

Second Version (NWoR4-6)
Following the victories of the third competition, the Great Wall was completely redesigned for Ninja Warrior of Roblox 4. This new version of the obstacle was much wider and had a much smoother curve. The tall window was removed in favor of a vertical wall with the TrussPart now hanging from an inverted wedge. This new version of the obstacle did a fair amount of damage in its first appearance, but seemed to be figured out the following competition, as no competitor would fail it in either of the two tournaments that followed.

Third Version (NWoR7-8)
The Great Wall was redesigned one last time in Ninja Warrior of Roblox 7, as the shape was changed to involve a relatively smooth curve the whole way through, along with the solid red and black colors being replaced with an entirely black wall with a red stripe down the center. This final version of the obstacle again eliminated nobody, but did act as a crucial timewaste for some before the final obstacles of the First Stage. It was replaced by the Warped Wall in Ninja Warrior of Roblox 9.

Ninja Bloxxer
The Great Wall also appeared in Ninja Bloxxer 1, 2, and 3 as the sixth obstacle of the First Stage. In its three-competition lifespan, it eliminated only three competitors, two of which incidentally slipped off the side of the wall into the water. It was replaced by the Warped Wall in Ninja Bloxxer 4.
