Obstacle course

Obstacle courses, (commonly known as an Obby (singular) Obbies, (plural), are a genre of experience in which users must complete various obstacles to win. Typically, obstacle courses include checkpoints at each stage or level and an area for winners at the end. 
Obstacle courses can vary in difficulty, length, or decor depending on the experience played. Each stage or level typically requires the player to use controls to complete it. More difficult obstacle courses may require extremely precise movements to complete. 
==Varieties==
There are many different formats to the obstacle course genre:
* Classic obbies - Classic obbies typically have very little decoration and an indistinct storyline. The levels themselves often feature generic platforms over a large void.
* Story-based obbies - Story-based obbies typically have a unique storyline to them, while giving the player obbies and sometimes minigames.
*Escape obbies - Escape obbies were typically much more detailed in decoration with a defined storyline compared to classic obbies. The main premise was to escape a building or object, like "Escape the Bank Obby", "Escape School Obby", and more.
*Clickbait obbies - Clickbait obbies typically abuse the search bar behavior by spamming the word "Obby" in the title and description to bring their experience to the top of the results. Each experience is typically just a republished version of an already existing obby. The experiences will often try to persuade the player into buying passes. Additionally, some of these experiences will teleport the player to another obby or completely unrelated experience upon completion.
*Difficulty chart obbies - Difficulty chart obbies originated from Tower of Difficulty Chart: Classic from Juke's Towers of Hell, and are designed to gradually increase in difficulty. There are checkpoints at every stage and players are, instead of aiming for the end, to go as far as possible and assess their skill. These obbies are usually based on some version of JToH's difficulty chart.
*Tiered Obbies - An obby that primary consists of a theme, usually difficult for the average player. They have a separate difficulty rating system, known as tiers. Apparently created by "", it goes up to 25 tiers as it gets harder and harder to complete.
*Tower-type obbies - These obstacle courses take the form of a (sometimes randomly generated) multi-floored tower, and the goal is to travel from the bottom to the top (except for a few unique towers where the end is at the bottom, there's also horizontal towers, but they are rarely used). Tower-type obbies often feature little to no checkpoints or safety nets, and as such are considered notoriously difficult. The origin of this trend, despite popular belief, is Obren's Inferno: Reborn (a remake of the original Kiddie's Towers of Hell, which changed ownership and became Juke's Towers of Hell).
*Troll Obbies - These obstacle courses have traps around the stages that seem normal (like the ground killing the player instead of the killbrick for lava jumps). An perfect example of this is I Wanna Test The Game, with the player having to jump around the first killbrick to avoid it going up and killing them.
==Parts==
Parts are different things that compose an obby. They are split into two categories: Normal parts and client sided objects. Client sided objects also have a short form, called ‘client objects’.
===Normal parts===
Normal parts are objects that have been created by the Roblox developers and easily accessible in Roblox Studio and other building games. Gameplay that only uses normal parts are called ‘purist gameplay/purism’.
======Parts/Blocks======
Parts are rectangular blocks. They are very basic objects, even though they can be rotated to make some fairly interesting or decent gameplay. They can also be used for decoration.
======Wedges======
Wedges are triangular prism shaped objects. Their triangle side resembles a right angle triangle. Wedges are basically just tilted parts except they are a less messy choice for tilted gameplay.
======Cylinders======
As the name suggests, it's a cylinder. The circle sides have a smooth texture for some reason. Gameplay that includes the curved side of cylinders are really weird, as your character loses speed when it approaches the very edge of the curved side.
======Balls/Spheres======
As these names also suggest, these parts take the shape of a sphere. These parts have the weirdest physics of all normal parts.
Currently, there is a glitch involving users on mobile devices teleporting in small distances around the sides and lower edges of spheres when coming into contact. No explanation has been given for why this is.
======Trusses ======
Trusses are a type of climbable part that is composed of 2 x 2 x 2 blocks with diagonal lines on the sides. You can edit the sides to have different amount of diagonal lines through. You can also extend a truss. A lot of tiered obbies and tower-type obbies include gameplay with this.
=== Client objects===
Client objects, short for client sided objects, are a type of obstacle generally originating from Juke's Towers of Hell. Client objects were created to make the overall gameplay of towers more fun and interesting, and their usage spread out to even difficulty chart obbies. Client objects, hence the name, use client-sided scripts to change an obby in a way where it only effects a specific player. For example, one player could stand on a brick which then immediately collapses, on another players screen the action wouldn't replicate and the brick would still be standing. This prevents players from messing with obstacles to prevent others from progressing in the obby. 
======Spinners======
Spinners are parts using a certain constraint that makes the part rotate. Due to the axis being a part itself, you can change its position allowing the spinner to rotate differently.
======Conveyors======
Conveyors push you in one direction. It's easy to understand. 
======Elevators======
Elevators are parts that push you in one direction, most usually upward. They are not collidable meaning you travel inside the elevator rather than on top of it like a conveyor. Once the top of the elevator is reached, your character is constantly propelled upward until the entire character is out of the elevator. Due to gravity, said character usually falls down into the elevator again, creating a sort of constant jumping sequence. Since the elevator is not collidable, as noted before, your character cannot jump while inside one.
======Buttons======
Buttons pulse a signal once pressed, triggering an event. For example, a button that activates a series of obstacles.
==Reoccurring obstacles==
There are many types of obstacles that occur frequently across most obby experiences.
===Common obstacles===
*Lava jumps - In these stages, players must jump over strips, usually made of lava/killbricks, without touching them.
* Tightropes - Narrow/curved parts players must walk over without falling. For PC users, it's mostly recommended to navigate through the cursor in first person, keeping cursor in tightrope's middle. Another solution that recommended is to press < and > (A.K.A. Alignment Keys), keeping the cursor still to the tightrope. Sadly, you can't do alignment keys in most of games because of roblox "Emotes on >" update.
* Platform jumps - Basic jumps from one part to another.
*Mazes- Trying to find the right path to exit the maze.
*Choose a path/door - A series of paths where the player must choose one of a series of paths or doors. Usually, only one path has the CanCollide property on.
**Sometimes the correct path is found using the camera on the part to see if CanCollide is on or not.
** Sometimes the incorrect paths kill the player instead of turning CanCollide off to avoid cheating by using the camera on the part.
** Sometimes the player can simply wraparound the doors instead of guessing.
*Climbing - Simple obstacles which require the player to climb up the ladder, usually a truss.
*Slide - Obstacles that require players to slide through them, to either bring players to another level or teleport them to other experiences.
** Using slides to teleport players into other experiences is mostly used by developers to get more place visits. Obbies with these kind of slides are referred to as teleport places.
*Speed obstacles - Course in which player speed is highly increased.
*Tree jumps - Platforms wrapping around a tall, central pillar.
*Wraparounds - Walls that must be jumped around (wrapped around).
*Rock climbing - Large and tall wall with small, randomly scattered ledges.
===Uncommon/complex obstacles===
Red text - patched
(Some techniques in this category are suited for mobile users) Obstacles that occur in more complex and difficult obstacle courses include:
*Long wraparounds - 8 to 12 stud walls that must be jumped around
*Wallhopping - Jumping on two horizontally touching bricks repeatedly (stopping will result in a fall/fail).
*Deep wallhop - Jumping on two horizontally touching bricks, except the higher brick sticks out up to about 0.3 studs.
*Ladder flicking - Similar to wallhops but on a truss or ladder, so the player will not jump repeatedly.
*Wall hugging - Walking on some kind of truss.
*Emote clipping - Use of Roblox Emotes to clip through 0.1-1.5 stud walls. (ex. Dance Clipping)
*Emote gliding - Use of Roblox Emotes to glide through walls. Laugh gliding usually allows 40 stud wall glides. The player can glide on walls of any length, but this requires skill.
*Spinner clipping - Clipping through a wall while standing on a 0.5 velocity spinner.
*Slope / Wedge Climbing - When your character touches the roof on a wedge, your character will have a climbing position. It was patched in late 2020, the most famous obby with a wedge climb was Homage.
*Lava wraparound - Wraparounds, except the wall is lava.
*Complex wraparound - Wraparounds with two or more mid-air rotations. Common in more difficult obbies.
*Corner clipping - Clipping through a corner on a wall or part to pass through it. This glitch is no longer possible.
*Book Clipping - It is the same as corner clipping, but it is more complex. This glitch is no longer possible as corner clipping is patched.
*Flat wall clipping - Ditto. This glitch is no longer possible as corner clipping is patched.
*Long jump - Jumps that are longer than 12 studs wide.
*Head hitters - Vertically aligned part blocks that require the player to Jump and move backward, then forwards to get on the next part. They are often seen in Tower of Hell experiences.
*Wallwalking - Same as wallhopping, but without jumping, and far more difficult. It is common in obbies that are made to be impossible, for example Citadel of Void.
*Long wrap tunnels - Wraparounds that are long and go through a 2 stud wide space or tighter.
*Glitchwrapping - Wraparounds that are impossible to do normally, so instead of doing it normally, the player will have to perform a quick corner glitch and jump. Long-distance glitch wraps are possible due to unknown reasons. This glitch is no longer possible as corner clipping is patched.
*Walkarounds - Wraparounds, but there is a part on the top making it impossible to fully jump. In no-jump sections where jumping is prohibited, there may not be a part on the top.
*Wraparound wallhop - Wallhop with a wraparound.
*Wraparound wallwalk - Wallwalk with a wraparound, these are borderline impossible and are generally only found in obbies that are made to be impossible.
*Ledge jumps - Whenever there is a ledge and there is a ceiling making it impossible to do the jump normally, the player will have to grab on the ledge, turn back, and then move forward to the platform the player is aiming to go to.
*Lodging - When in a 2.2 to 1 stud gap, the player must turn their camera if their avatar's legs touch the colored parts.
*Wall lodging - When in a 1.5 stud gap, the player must make their character face 45 degrees left or right, and hold W and D. If right, W and A, if left, then the player will slowly start floating.
*Lag clipping - Hold down the top of their window and then walk forward.
*Truss clipping - Basically corner clipping, but the player has to do it fast since the player is on a truss. This glitch is no longer possible as corner clipping is patched.
*Emote jumping - Without jumping, the farthest the player can get up a platform at once is two studs. With a technique similar to dance clipping, the player can go up a 3 stud thick platform. All emotes, except /e point, can be used for this technique.
*Instakill stepping- The player has to flick their camera left to center or right to center, and if the player is lucky, they will not die.
*Luck clipping - Same as lag clipping, but without holding the window. It is also possible with broken physics, although this was patched.
*Fling control - The player has to fling themselves but use any form of loophole in Roblox physics to control where the fling sends them to.
*Wedge flinging - Jump off a high platform onto the edge of a wedge facing sideways. This will fling the player forward.
*Wedge fling wrap - Same as wedge flinging, but while the player is flung forward, the player has to do a wrap in mid-air.
*Emote jumping - The use of emotes to get a button. This does not seem to have any use on "purist" obbies.
*Dance jumping - This technique that uses /e dance2 is similar to /e salute clipping on R15. It allows an 11-stud high wall jump, even if there is a two-stud stickout jumparound.
*Vertical book clipping - Like book clipping, except it's vertical. It is usually built on a slope or wedge, because doing them normally is time-taking. This glitch is no longer possible as corner clipping is patched.
*Vertical flat clipping - A very hard common glitch, they are built to be one of the most unthinkable gameplays.
*Flat wrapping - A flat clip jump that involves your character facing the crack between the walls while having your camera 90 degrees turned to make you do a glitchwrap. This glitch is no longer possible as corner clipping is patched.
*Lodge glitching - Glitches that are performed while lodging.
*H-glitching - These glitches are more difficult than a flat clip, the walls makes a pattern looking like the letter "H" and you will have to clip through it from the corner made by the 2 blocks. It works like a reverse book clip.
*Extreme slope climbing - Climbing slopes that are tilt by 2 degrees and more than 0 degrees. Slope climbs that are exactly tilt by 0.05 degree are known as Octogoat YT jumps, because he has discovered an easier technique to these obstacles, which is to approach the wall and turn your character by a bit.
*Deep obstacles - These obstacles are used to design tiered obbies that are around tier 12 or higher. Where the upper block is thicker than the lower block with thickness ranging from 0.2 stud to 0.95 stud, when flicking off from one of these obstacles on a truss, turn your camera more than 30 degrees and zoom in / turn on shiftlock to jump off.
*Lag truss bounce - When there is a gap, both sides are unclimbable (3 studs thick or more) with an unclimbable truss in the part and a roof on the top, align the character well, jump once, and hold down the top of the window, there is a chance that the lag will send you down to the truss.
===Mid-air glitches===
*Mid-air corner clip - Same as corner clipping, but the player has to do it mid-air. It is common in obbies that are made to be impossible. This glitch is no longer possible as corner clipping is patched.
*Mid-air book clip - Same as book clipping, but the player has to do it mid-air. It is common in obbies that are made to be impossible. This glitch is no longer possible as corner clipping is patched.
*Mid-air luck clip - Same as luck clipping, but the player has to do it mid-air. It is common in obbies that are made to be impossible.
*Mid-air flat wall clip - Same as flat wall clipping, but the player has to do it mid-air and it is luck-based. This glitch is no longer possible as corner clipping is patched.
*Mid-air lag clip - Same as lag clipping, but the player has to do it mid-air and it is luck-based.
==Winner Area==
Some obbies typically have a special Winners area that can include prizes like tools, character customization, and more:
*Tools:
**Path tools can be used to be transported from one area of the game to another quickly. They are activated by holding the left mouse button and moving the camera and player to navigate. Historically, paths could be used to interfere with other players completing the obby, but this is no longer possible due to recent Roblox updates.
**Superjump tools allow the player to jump abnormally high. These tools are less frequent in modern obby games as Roblox updates have broken them.
**Teleport tools allow the player to teleport where they click. Similar to Superjump, they are less frequent in modern obby games as Roblox updates have broken them.
**Social tools are occasionally given, including gear like Bloxy Cola, Teddy Bloxpin, and more.
*Avatar customization - An avatar customization area can sometimes be found at the end of an obby. This area includes parts that change the player's character's face upon touch, skin color changers, various hairs and hats that can be put on, and more. These changes do not save if the player dies or leaves the game, however.
*Speed squares - In some obbies, in the end, colored squares that say 50% Speed would make the player's character walk faster when stepped on.
*Badges - Most obbies have badges at the end of the obstacle course or every few stages. Most obbies can give these badges for essentially free by hacking.
==Criticism==
Around 2013, Builders Club members created obstacle courses that claimed to award free Robux, tickets, or Builders Club. However, these experiences were scams as it is not possible to gain free currency or membership. These experiences were typically built using the building tools included in personal servers.
Obby experiences have also been the culprit of deceptive advertising, with misleading thumbnails and other assets since their conception. Generally, the quality of obbies in recent years has gotten better due to developers putting effort into the detail and gameplay of their experiences. However, clickbait still runs rampant.
==Trivia==
*Difficulty chart obbies usually have a low like-dislike ratio because most players are tired of cliché trends or being too difficult.
*Currently, the most difficult obby completed legitimately (no checkpoints, no TAS/replayability, no exploits) is Tower of Spiralling Fates. was the first player to complete it on 26 October 2024.
*Searching "obby" on Roblox will likely give results for escape and clickbait obbies.
*Tower of Hell is the most visited obby, with over sixteen billion visits.
*Corner clips, flat clip related glitches are recently patched.
**When Corner clips got patched, JToH made a new update where they added a new type of CCs: Corner Flips.
