Bridge of Blades

Ninja Warrior of Roblox
The Bridge of Blades, or sometimes know as the Cross Bridge, were first used in Ninja Warrior of Roblox 12. It consisted of a series of eight panels, alternating in color from red to blue. Competitors were to cross the panels without falling into the water or touching the middle. Due to the reconfiguration of the First Stage that competition, it was placed in the sixth position, directly following the Jumping Spider. Because of this, only twelve competitors were even able to reach it, and it posed very little of a threat to those who did. While some competitors had a few close calls, no one ended up failing the obstacle and it was replaced with a much more lethal obstacle in Ninja Warrior of Roblox 13, the Bungee Bridge.

Ninja Bloxxer
This obstacle appears in Ninja Bloxxer 7, as one of the many new First Stage obstacles in the tournament. This version of the obstacle is a much more traditional build, made up of four panels all on one hinge. Unlike the Ninja Warrior of Roblox version, competitors were allowed to use the middle of the obstacle to cross it, and while most competitors used it to their advantage, the obstacle still did a fair amount of damage. While the obstacle is primarily called the Bridge of Blades in Ninja Bloxxer, it is referred to as the Cross Bridge in the failure cards for the seventh tournament due to space limitation.
