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 with 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. 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. It appeared as the 8th obstacle both in Baltimore in Season 5 and St. Louis in Season 6. 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 8th obstacle in the Venice Finals of American Ninja Warrior 7. There are 2 dice instead of 1.The first one weighs 30 lbs and the 2nd one weighs 50 lbs.
