The Rumbling Dice (ランブリングダイス) is an obstacle introduced in the Third Stage redesign in SASUKE 9. It is kind of like the Pipe Slider in a form of a box instead of a pipe. The competitor must hang from a metal box and roll it along a track to get to the other side, where there is a landing platform. While it was more to drain strength for later in the stage, only two people: Yamamoto Shingo in SASUKE 9 and Yamaguchi Kosuke in SASUKE 14 have ever failed it and it was replaced by the Arm Rings in SASUKE 16. In both cases, the competitors made it to the end but didn't get enough momentum and fell off the platform. Starting in SASUKE 15, the height may have reached on the starting point without jumping, but it left the rail a little slippery, so the idling is noticeable. It eventually returned in SASUKE 28 and removed in SASUKE 31 in favour of the introduction of Sidewinder R.
The Rumbling Dice has appeared in 3 city finals courses on American Ninja Warrior. It appeared as the eighth obstacle both in Baltimore on American Ninja Warrior 5 and St. Louis on American Ninja Warrior 6. In St. Louis, Joe Moravsky became the first ever competitor to "break" the obstacle, pulling one side off of the rail. He was able to still complete it. It returned re-modified as the eighth obstacle in Venice Beach finals on American Ninja Warrior 7. There were two dices instead of one.The first one weighs 30 lbs and must make a 4 ft. transition to the second one, which weighs 50 lbs.
