Rumbling Dice (ランブリングダイス) is an obstacle introduced during Third Stage's redesign in SASUKE 9. Competitors must hang from a metal box, rolled it along a track to get to the other side to make the dismount to the landing platform to advance. It will eventually replaced by Arm Rings in SASUKE 16.

While it was more to drain strength for later obstacles in the stage, two competitors have ever failed on the obstacle: Yamamoto Shingo in SASUKE 9 and Yamaguchi Kōsuke in SASUKE 14. In both cases, both competitors made it to the end, but didn't get enough momentum and fell off the landing platform.

For unknown reasons, competitors were allowed to wore gloves while attempting this obstacle, as proven by Kobayashi Shinji in SASUKE 11. He will then remove the gloves after clearing the obstacle.

The obstacle receive a minor modification in SASUKE 15, where it was made lower, making it possible for competitors with a great height to reach the starting point without jumping, but it left the rail a little slippery, so the idling was noticeable.

Rumbling Dice then returned once more in SASUKE 28. In this version, the dice was noticeably smaller and heavier compared to the original version, with the track was also shortened and lowered compared to the original version. Again served as energy drainer for the later obstacles in the stage, it didn't eliminate any competitors this time and it will only stay for three tournaments before being replaced by the relocated Drum Hopper in SASUKE 31, which moved in placement due to the introduction of Sidewinder R.

American Ninja Warrior

American Ninja Warrior 5's Rumbling Dice in Baltimore

Rumbling Dice appeared as the eighth obstacle on:

The obstacle used on American Ninja Warrior 5 and 6 was similar to the Rumbling Dice from SASUKE.

Joe Moravsky broke the Rumbling Dice during American Ninja Warrior 6's St. Louis finals

During American Ninja Warrior 6's St. Louis finals, Joe Moravsky became the first ever competitor to "break" the obstacle, pulling one side off the rail, due to the diagonal grip instead of usual parallel grip between two hands. Luckily, he was able to complete it, thanks to the early dismount from the obstacle.

American Ninja Warrior 7's Rumbling Dice in Venice Beach

On American Ninja Warrior 7, the obstacle was modified with two dices instead of one. The first one weighed 30 lbs (roughly 13.61kg), and after completing the first dice, competitors must make a 4-foot transition to the second dice, which weighed 50 lbs (roughly 22.68kg). To avoid further happenings such as happened with Joe Moravsky during American Ninja Warrior 6's St. Louis finals, there were wires attached to both sides of each dice, which prevented the competitors to pull the dices off the rail.

Since the obstacle was placed after the Salmon Ladder with no rest, the Rumbling Dice had eliminated more competitors on American Ninja Warrior than in SASUKE, likely due to fatigue and bad dismount to the landing platform.

American Ninja Warrior: Ninja vs. Ninja

American Ninja Warrior: Ninja vs. Ninja's Rumbling Dice

On American Ninja Warrior: Ninja vs. Ninja, the Rumbling Dice appeared as the eighth and penultimate obstacle of the extended course during Final Matchup, which was very similar to the one used during American Ninja Warrior 7's Venice Beach finals, with the appearance of two dices. However, there were several noticeable differences:

  • Both dices were at the same height, size, and weight, and
  • After finishing the first dice, instead of jumping to the second dice, competitors must grab a laché bar and make the transition to the second dice.

SASUKE Vietnam

SASUKE Vietnam 2's Rumbling Dice

Lật xúc xắc (SASUKE Vietnam's official name for the Rumbling Dice) appeared as the third obstacle in Stage 3 on SASUKE Vietnam 1 and SASUKE Vietnam 2.

During its overall appearances on SASUKE Vietnam, the obstacle had caused an unusual disqualification, as several competitors were disqualified for incidentally sliding the dice forward instead of rolling it along the track.

It was replaced by the Pole Grasper and Hang Climbing on SASUKE Vietnam 3.

Australian Ninja Warrior

Australian Ninja Warrior 2's Rumbling Dice

On Australian Ninja Warrior 2, the Rumbling Dice appeared as the seventh obstacle in Stage One, which was very similar to the one used on American Ninja Warrior: Ninja vs. Ninja, except no laché bar placed between the dices. Also, there was a rope at the start of the obstacle, as a medium to reach the first dice. It was revealed as the weight of each dice was 22kg.

While there were wires attached sideways of the dice similar to American Ninja Warrior 7 version, it could still roll off the track, as two competitors, Olivia Vivian and Luke Williams, broke the first and second dice respectively, with the same reason of diagonal grip between two hands. Unfortunately, unlike Joe Moravsky's situation, the wires itself made the dice completely unstable as the dice could move back, forth and spin out of control. Because of that, both two competitors failed it.

Ninja Warrior Poland

Ninja Warrior Poland 4's Rumbling Dice

At Ninja Warrior Poland 4, Rumbling Dice appeared in the final as the fourth obstacle in Stage Two. This version was similar to that used in American Ninja Warrior 7, with two dice. None of the competitors fell on this obstacle.
