The competitor must jump over a small pit onto a staircase of logs that each freely rotate on a lateral axis, then climb that to the next obstacle.
Quintuple Step
The competitor must jump across 4 platforms that are angled 45° degrees toward the center of a water pit, and then jump to the platform at the end. The platforms are positioned alternately, left and right, across the length of the pit. They are each 60 centimeters (1 ft 11.62 in) wide, and the total length of the obstacle is 6.2 meters (20 ft 4.09 in).
Hill Climb (12th competition)
The competitor must cross over two small hills which are at a 60° incline.
Prism Tilt
The competitor must jump over a small pit onto a large triangle which is supported by an axis in the center. The weight on one side of the triangle will tilt it into the water, so it must be crossed quickly.
Cone Jump
The competitor must cross two large cones that are spinning and jump to the next platform.
Hurdle Jump
The competitor must cross three pits, the first one where the platforms they jump from have bungee-rope hurdles. The first platform is shaped like an opening quarter-pipe, the second is flat and inclined to about 30°, and the landing platform is inclined to about 45°.
Sextuple Step
A modification of the Quintuple step, the number of intermediary platforms was increased from 4 to 5 it was added to the course in the 16th competion and removed in the 18th competion but it was returned in the following competion because of the Rope Glider being too dangerous.
Rope Glider
The competitor must hold onto a rope as it slides down a track, and then let go to land on a mat floating in the water. Due to multiple injuries in the 18th Tournament, the obstacle has since been removed.
Butterfly Wall
The competitor must jump and grab onto a vertical wall that spins around a central vertical axis to reach the platform on the other side.
Spinning Log
The Competitor must cross a horizontal log that freely rotates around a central axis parallel to the course. The log is about 3 meters long and 20cm in diameter.
Log Slope
A modification of the Spinning Log, the log is now on an incline of about 15°, and the exit ground is placed above the log. It is also positioned like a platform rather than a balance beam and requires an additional climb to a platform leading to the next obstacle.
Rolling Log
The competitor must straddle and cling to a log 40 centimeters (1 ft 3.75 in) in diameter before kicking the ground to begin its roll down a 15° decline. Since the 13th competition, drops were implemented into the two supporting rails causing the log to fall, jarring the competitor. The log is also notorious for coming off the tracks and halting its spin midway.
Log Grip
The competitor must hold onto a vertical log with their arms and legs while it slides down a track with drops to the next platform. The log contains small indentations to provide some grip. The track is similar to the one previously used for the Rolling Log, but the the drops are are bigger and the track is longer.
Rapid Descent
Exactly like starting from the other end of the Barrel Climb, the competitor must jump over a large gap.
Balance Bridge
There is a large board that freely rotates along an axis parallel to the course. Along with this, there is an extension along the axis that sticks straight up. When the Balance Bridge was reused in the 11th competition, the axis was further to the left, the extension went along the whole board, and there was a second extension added perpendicular to the first on the right side halfway across the obstacle.
Big Boulder
The competitor must jump onto a very large boulder-like sphere floating in water and leap across to the other side.
Dance Bridge
The dance bridge is made of 12 individual boards that each spin individually on three lengthwise axes then jump to a platform.
Plank Bridge
The entrant must jump off half a bridge to the other side. The board is unanchored, and falls as the contestant runs across it.
Bridge of Blades
Like the other bridges, the Bridge of Blades rotates freely around a central lengthwise axis. The Bridge of Blades has four sections of bridge alternately going out 45° on each side. There is also an extension that spans the whole bridge that comes straight up about 15cm high.
Pole Maze
The competitor must grab a pole leaning against the first platform, and swing to the other side. The pole is anchored in the middle of the water pit between, and the top of the pole must be guided through a track above.
Circle Slider
The competitor must jump from a springboard and grab onto a large hoop which is on a long track on a decline, that they must slide across. At the end, the hoop hits a large object on the top of the track, and the competitor must use the momentum built up on the descent to swing to a platform.
Jump Hang
The competitor must bound forward off a trampoline to grasp the underside of a declining cargo net, then either climb over or underneath it, taking care not to touch the water below the obstacle if they choose the latter route. In the 13th Competition, there were many hanging ropes to grab onto rather than the cargo net.
Jumping Spider
A combination of the Jump Hang and the Spider Walk from the Second Stage where the competitor must jump from a trampoline into a shaft of parallel walls that they must traverse by wedging themselves between and crawling through them. In the 19th Competition, the platform before the trampoline was shortened making the competitor to jump up in a forward manner, instead of just jumping straight up to the walls.
Bungee Bridge
The competitor must cross a bridge of 4 planks with a gap between each. The planks are made of many thin strips of a stretchy material so they provide little support and very unstable ground.
Rope Reverse
The competitor must take a rope and swing off the side of a high platform. When the rope swings back into the side of the high platform, the competitor must swing and jump onto another platform below. There is a bungee line that limits the rope's movement.
Reverse Fly
The competitor must jump into a large vertical trampoline, slightly angled, and then land back on a platform next to the one they jumped from. A wall divides the platform they must jump from and land on.
Crooked Wall
The competitor must run up a concave wall and jump off the side to grab a rope which will then take them to the next obstacle. The wall is curved more on one side than the other. There is also a rope called Seesaw Rope.
Halfpipe Attack
In a fashion quite similar to the Crooked Wall, the competitor must run up across a half-pipe spanning from the floor to the ceiling on one side. Afterwards, they must make a leap from the half-pipe about halfway through to reach a rope to swing themselves to a platform that will lead them to the next obstacle.
Hill Climb (1st-4th competition)
The competitor must climb one large wall of similar height to the warped wall, but flat and a 60° angle.
Warped Wall
The competitor must scale a concave quarter-pipe by running up and grabbing the top of the wall. From the 5th to the 17th tournaments, the wall was 5 meters (16 ft 4.85 in) high. In the 19th tournament, the height was raised to 5 meters and 20 centimeters (17ft). After the 13th competition, for contestants 13 and under and 50 and older, a portion of the wall can be taken off of the top, making the wall about one foot shorter.
Great Wall
What seems to be a merge of the Warped Wall and the Crooked Wall,(Execpt Seesaw Rope)the Great Wall adds an extra piece of the wall on top of the Warped Wall with a rope hanging over the end for contestants to grab and climb over with. The rope ends at the same height as the original Warped Wall.
Flying Chute
The competitor must sit down and slide down a concaved slant and grab onto a rope hanging horizontally at the end, then transfer from that rope to a net behind them and climb down. In the 19th competition the rope was placed further away from the chute, making it much more difficult by requiring the contestant to jump for it.
Tarzan Jump
The competitor must cross a series of 5 hanging ropes (which stretch as they are pulled) to a rope against the wall, which they then must climb to reach the buzzer before time expires later it was decreased to 4 ropes starting in the 11th Competition.
Mountain Climb
The competitor must climb a wall with hand and foot holds to reach the buzzer at the top. The first section of the wall is on a conveyor belt that moves slowly downwards as the contestants climb.
Rope Climb
The competitor must take a rope and swing to a wall, then climb up the wall with the rope to press the buzzer before time expires.In the 10th-12th competitions the rope was against the wall so the contestents must use the Tarzan Jump to reach the obstacle.From the 18th competition and onward it was made into the Tarzan Rope where it preceds the Rope Ladder as explained below.
Tarzan Rope → Rope Ladder
The competitor must take a rope and swing to a net wall, then climb up the net and cross a short bridge to press the buzzer before time expires. The rope is similar to the Rope Climb as it appears.
There have been a few different versions of this obstacle. In the first few competitions, it was the first and longest obstacle, sometimes taking as much as half of the alloted time. The obstacle required the competitor to pin themselves between two parallel walls and traverse it without touching the ground. A segment in the middle moved up and down, requiring a shift in direction usually. Later, it was shortened to five large sets of panels, each of which moved independently of the others. In the version used from the 7th to the 17th Competition, the competitor must use his hands and feet to climb up, across, and back down two parallel walls. The two versions used in the 1st-6th tournaments ends at a pole to slide down referred to as the "Fireman's Pole". A can of adhesive spray is available at the start of the obstacle. Bare hands must be used or the contestant will be disqualified. (This requirement is especially important starting in the 7th Competition, since the Chain Reaction uses gloves.). Also, in the 1st-3rd competitions, throughout the entire obstacle there were only waiting mats to fall on. In the 4th competition, the first of the obstacle, to fall on was water, but mats the other half. From the 5th-17th competitions, the whole obstacle was filled with water to fall in. Also, the Spider Walk used in the first 4 tournaments had an ascending area that the Japanese announcer referred to as the "Spider Climb", yet however,this area is of no relation to the "Spider Climb" that was found in the 5th-17th competitions' Final Stage.
Tackle Machine
The competitor must push a 50kg weight down a tunnel to reach the exit to the next obstacle.
Ledge Walk
The competitor must cross two sections of ledge at the bottom of a wall, with water below. The second section has two short strips sticking out of the wall at about knee height to increase the difficulty.
Chain Reaction
The competitor must ride two sequential zip-lines over a pit of water, switching between them in midair. The zip-lines travel perpendicularly to each other, and each has a chain hanging from it by a single point. Competitors must grasp the chain on the first zip-line, ride to where the first chain slams into the scaffold, then switch to the next chain in midair, and ride the second zip-line to the end of the obstacle. During the switch, competitors may kick off a nearby solid wall. The first swing is 9.5 meters, and the second is 7.5 meters. Competitors are required to wear gloves (for safety reasons) when holding the chains which they must discard prior to reaching the Spider Walk.
Downhill Jump/Super Jump
The competitor must slide down a track standing on an object similar to a snowboard, then jump to a rope on a track, which then swings towards a mat which the competitor must jump onto. Kunoichi's Super Jump is similar to this. In fact, the 19th Competition dubbed this obstacle as the Super Jump.
Brick Climb
The competitor must climb a wall with bricks protruding from it. The wall is approximately 3.5 meters high.
Salmon Ladder → Stick Slider
The competitor must grab a bar which is resting on two parallel walls. The walls have seven parallel sets of notches for the bar to rest on, and the gap between the last two sets is larger than the previous gaps. The bar is not bound to the wall in any way. Once the bar is grabbed, the landing mat from the Downhill Jump is taken away. The competitor must use his momentum to climb, raising the bar from notch to notch. After reaching the final notch, he must land the bar onto two tracks which come in towards each other as the competitor slides down. Finally, he must drop from the bar onto a mat below.
Hammer Dodge
The competitor must walk across a thin plank, taking care to avoid 5 large hammers which are swinging back and forth. In a few competitions, the competitor is disqualified for coming into contact with the hammers in any way, while in others, the competitor just has to go through without falling.
Balance Tank
The competitor must balance atop a large rolling barrel and ride the barrel to a platform across a distance of 5.4 meters.
Grip Hang
The competitor must hang onto two outward-facing ledges and cross a small gap.
Net Bridge
The competitor must climb across a cargo net to reach the next platform.
Sky Walk
Little is known about this obstacle since no competitor has had the chance to attempt it. It appears that the competitor must use only a long narrow ledge plus a wall for support to climb across a large gap. Its function is likely similar to the Cliff Hanger.
Swing Ladder
A set of monkey bars must be crossed by the competitors. The monkey bars are set on a tilting mount on the scaffolding above. It is similar to Kunoichi's "Climbing Bars".
Reverse Conveyor Belt
The competitor must crawl though a small tunnel with a conveyor belt going the opposite direction. It is 90cm wide and 6.3 meters long.
Metal Spin
An array of chains dangle from a horizontal wheel that freely spins, resembling a chandelier, over a water hazard. The competitor must jump to grasp one of the chains, spinning the wheel to the other side. Starting in the 16th competition, the chains were replaced with plastc bungee chains, making it difficult to hold on the chains unless with a strong grip to prevent the chains from slipping out of the competitors hands and withstand the whiplash effect.
Wall Lift
Three walls block the competitor, who must lift and cross under them to advance. Initially, the walls were 20kg (44 pounds), 30kg (66 pounds), 40kg (88 pounds). Later, they were increased to 30kg, (66 pounds) 40kg (88 pounds), and 50kg (110 pounds). It was replaced by the Shoulder Walk in the 18th competition, but then returned in the next competition, where it was shown that the walls were changed from steel to wood.
Shoulder Walk
The competitor must cross two bridges carrying a bar on his shoulders that has two weighted chambers hanging from each end of the bar, weighing 40kg (88 pounds) total. The bridges have a small gap between them, and the second bridge is offset to the left.
The competitor must pole vault over a body of water. The pole is unanchored. Kunoichi's Super Vault is similar to this.
Pillar Path
The competitor walks across a path of unstable columns. This is one of the only obstacles that did not have a water pit to fall in.
Propeller Bars
The competitor must cross a series of 3 horizontal, slowly-spinning bars anchored to the top of the course.
Needle Climb
Although it is not an official name, since the 1st competition wasn't broadcast in G4, the competitor must cross a patch of large, thin, flexible poles that protrude up from the ground, by using arms and legs. This is one of the only obstacles that didn't have a water pit to fall in. It was the last obstacle of the 3rd stage, since the Pipe Slider wasn't introduced yet.
Rumbling Dice
A box frame made of two steel squares connected by four monkey bars, one at each corner about 30cm apart from one another, is placed on two bars that traverse a 5m water pit. The competitor must roll the box frame across the pit by grabbing the top monkey bar in front and pulling it down again and again.
Arm Rings
The competitor hangs from two rings on different-shaped sliding horizontal poles and has to negotiate several rises and dips on the poles.
Chain Swing
The competitor must cross a series of 6 hanging chains about 2.5m long, each of which has a wooden foothold at the bottom.
Arm Bike
On this obstacle, the competitor must use his arms to propel himself across the gap, holding pedals similar to the way feet pedal on a bike. This obstacle was used from the 4th Competition until the 9th, and then returned in the 18th Competition as an immediate successor to the Arm Rings, with no platform to rest on between them.
Body Prop
Much like the Spider Walk, the competitor must traverse an expanse of two walls that are 5 meters long. However, the walls are further apart, so he must position both hands on one side and both feet on the other. His body should be parallel to the ground as he does so. Along the way there are breaks in both walls, requiring the entrant to negotiate those as he moves across.
Globe Grasp
The competitor crosses yet another pool of water by grabbing onto a series of small glowing blue spheres attached to the scaffolding above. Known as "Lamp Grab" in Japan.
Descending Globe Grasp
A modification of the "Globe Grasp" obstacle. In this version of the obstacle, the apparatus on which the spherical handholds are attached is slightly declined, requiring the competitor to reach downward to each successive sphere then jumping across a small gap.
Curtain Cling
The competitor must grapple across a hanging curtain 5.4 meters wide to reach the other side. The curtain is about 3m (9 ft 10.11 in) in height.
Curtain Swing
Four small curtains 1m (3 ft 3.37 in) long are hung diagonally, and the bottom of each is within arm's reach. The entrant must swing from one to the next to get across.
Devil Steps
This obstacle is a set of ascending and descending stairs, but instead of walking across over them, the challenger must climb through the bottom of these steps to reach the next obstacle.
Cliff Hanger
The competitor must traverse three narrow ledges only large enough to be supported by the fingertips (1 inch wide). Since its introduction in the 4th tournament, there have been four different versions.
The original obstacle had the three ledges at the same height, all the same length at 1.2m (3 ft 11.24 in) each, with 15cm (5.91 in) gaps between them.
In the following competition, the third ledge was raised 30cm (11.81 in).
For the 9th competition to the 17th, the first ledge was lengthened, the second ledge was raised to the height of the third, and the third was lowered 45cm. (17.71in)
For the 18th competition, the second ledge was shortened and inclined, making the gap between the second and third bars 1m (3 ft 3.37 in) horizontally. As a small compensation for the added difficulty, the first half of the last bar is thicker, making it slightly easier to grab onto after the jump. As of the 20th Sasuke, no competitor has been able to successfully complete this incarnation of the Cliff Hanger. Since the 19th competition, a diagonal sheet of metal has been added to prevent grabbing the top of the third ledge, as Nagano did in the 18th competition.
Jumping Bars
Competitors must jump from a series of bars, each one about 5 feet in front of and one foot below the previous. This obstacle is in a pair along with the Climbing Bars.
Climbing Bars/Bridge Of Destiny
Competitors must climb across an inclined ladder while hanging underneath it. Since its introduction it has been preceded by the Jumping Bars, and the two drain what little stamina the competitor has left.
Ascending Climb
Replacing the Climbing Bars in the 19th competition, it's presented as an acutely angled wall scattered with modern wall climbing artifacts. This takes place between the Jumping Bars and the Spider Flip with no resting platforms. No competitor has attempted this obstacle to date.
Devil's Swing
Competitors must swing on a trapeze bar attached to the top of the obstacle course by two chains and swing to the bar on the pipe slider. There is a risk of getting the chains stuck on the green rest bar behind the obstacle, and also a risk of grabbing the Pipe Slider, only to have the pipe rolling away on the track.
Pipe Slider
Introduced in the 2nd tournament and used until the 17th, this obstacle is historically the last obstacle on the course. The entrant must hang from a pipe and, by undulating his body, move that pipe across a track to the other side. There have been two versions of this obstacle. In the earlier version, there would be two tracks to slide down, the first continuing in the same direction as rest of stage three, whereas the second was perpendicular to it with only a green bar at a 45° angle between them though there used to be a black bar. In the 14th competition, the first track was eliminated and replaced with the Jumping Bars and Climbing Bars. Once the competitor reached the green bar, he must use the Devil's Swing to reach the Pipe Slider track, and slide down to the end and the gap between the piper slider and the finishing mat was increased by another 2 ft. Starting by the 4th competition, the competitors must swing off the pipe to the finish mat, unlike in the 2 previous competitions where the competitors may get off the pipe slider without swinging since there wasn't a gap from the end of the track to the finishing mat.There have been cases where the pipe falls off the track after getting on the finishing mat.
Spider Flip
This obstacle replaces the Devil's Swing in the 18th competition. Although no competitor has made it to this obstacle in the competition, the obstacle itself was taken from the "Heartbreaker" on Viking: The Ultimate Obstacle Course. A ledge, much like an I-beam girder where there is a lip to hold onto on either side, must be climbed to the end where another one of these ledges, aligned vertically, must be scaled. There is a foothold on this one. Next, the competitor must jump backwards about 2 meters and land onto another another setup symmetrical to the first, and climb back down and across.
Final Ring
This obstacle replaced the Pipe Slider in the 18th competition. Although no competitor has made it to this obstacle in the competition, its appearance is similar to the "Circle Slider" obstacle. However, the track is shorter, but is on a small incline and the ring is smaller. Its function seems to be similar to the pipe slider, where the competitor needs to swing off the ring over a fairly large gap onto the finishing platform to reach the final stage. While the obstacle hasn't been shown in full detail yet, the ring seems to be at an angle and there is only one pole of track to hold the ring. The gap also seems to be wider. This seems to suggest that the Final Ring is an all-or-nothing shot, where the only possible way to complete it is to swing off on the first try, especially with the small incline of track.
