Competitors have to go down a slanted pole and must hold on. After that, they must traverse to the first cube with ledges around it, which competitors must make a long reach to grasp onto the ledge on the top of the first cube. Then, competitors must make a 6-foot transition from the first cube cube to the second cube, which is smaller and trapezoidal in shape. After that, they must traverse around the second cube, utilizing its ledges, and make a jump to the landing platform.
This obstacle was proven to be immensely difficult, as it took out several competitors like Ryan Stratis, the "Brazi Bros" (Alexio Gomes and Lucas Gomes), and Reko Rivera. A total of ten competitors failed on the obstacle, typically due to struggling on the reach on the first cube or making the leap transition to the second cube.
A unique and interesting completion of this obstacle occurred during Daytona Beach finals, when Jessie Graff used an unorthodox way of making the transition to the second cube. Instead of making the leap transition to the second cube, she was doing the split, by putting her left foot on the second cube, while her right foot was propped to the first cube, in order to make an easier transition, and making her completed the obstacle and going all the way to the Elevator Climb. Later that night, Travis Rosen also tried her method on the transition and successfully completed this obstacle and going all the way to the Circuit Board. While on the other hand, Drew Drechsel tried her method on the transition, but failed to make it, despite being nearly the same height. Fortunately, he instead used the traditional method of transition from one cube to another, and cleared the obstacle, along with the course altogether.
On American Ninja Warrior 10, the Giant Cubes appeared as the eighth obstacle during Los Angeles finals. This time, the slanted pole was replaced with a trapezoidal board with a ledge around it (similar to the one used on the second cube of the obstacle).
Despite that, the obstacle was proven to be easier than during Daytona Beach finals on the previous season, as only 4 competitors fell on it. Also, most of the competitors who completed the obstacle used Jessie Graff's technique while making the transition between the cubes.
