The UBER challenge was a challenge with heavy restrictions, created by Mario64Masters in 2009. This challenge inspired many related challenges deriving from the ruleset, such as Capless, Cannonless, and Coinless Challenges (and combinations of them such as CCC Challenge). The name of the UBER challenge was borrowed from Manocheese's Über Challenge for Ocarina of Time.
The last possible star collected with TAS was completed on February 8, 2010. Although the challenge is now over as there are no more stars that are possible to collect, it remains one of the early pieces of development in exploring the mechanics of Super Mario 64, as object-clipping, BLJing, and advanced wall kicking are required to work around the restrictions.
The rules were as follows:
- Any coins should NOT be collected.
- No collecting or activating 1up mushrooms (lives).
- No gathering "collectibles" of 5. (Chests are allowed as there are only 4 of them).
- No pressing any switches (e.g. Purple switches, cap switches).
- No shooting from cannons.
- No using teleporting spots.
- Never lose your cap.
- Never wear any of the three special caps (except for when Mario automatically wears the wing cap when you finish the game).
- Boxes cannot be opened unless there is a star inside.
- No deaths.
- No damage from ANYTHING EXCEPT large falls and water. You can regain health from anything that is allowed.
- No activating the motion of any movable platform (including elevators) except those whose central position cannot be changed.
- Allowed: Seesaws, rocking platforms and the falling block in the volcano.
- Any other platform may be used if the way you use it does not affect its motion (like sets of 4 cycling checker blocks).
- No using the switches in Wet-Dry World to change the water level.
- The swimming beast in the Hazy Maze Cave cannot be touched, nor can any penguin.
- Excluding scenes at the start and end of the game, the only characters you can talk to are the rabbit and Bowser.
- Updrafts may not be activated. Side drafts may be used as long as they do not blow off your cap.
- No combat with anything except Bowser and the rabbit.
- Enemies may not be killed even if it is not directly an act of Mario. This includes enemies falling off an edge as well. You may only continue if it lands on a platform Mario can walk on glitchless.
- No touching any enemy (except Bowser or MIPS).
- A Thwomp, Grindel or Spindel is not an enemy as it is basically a moving platform. (You still must not get hurt by it)
- No entering any warp pipes in Tiny-Huge Island.
- Hacks are COMPLETELY FORBIDDEN (savestates are only allowed when practicing)
- No touching the cartridge or power cord intentionally while playing.
- Any version of the game is allowed (except DS).
- At least 15 stars must be collected before entering Dire, Dire Docks. You must get the star "Board Bowser's Sub" in Dire, Dire Docks. (This is to prevent Side BLJ skip from being used to skip directly to Bowser in the Fire Sea)

With TAS, there are seven more stars that can be collected under these restrictions. These stars do not count towards the original UBER challenge since they are nearly impossible to perform RTA. The numeric orders are according to the time the strategy was found:
- 40th star - HMC: Metal-Head Mario Can Move! (BLJ against the grid wall using a slope is required, RTA possible)
- 41st star - HMC: Navigating the Toxic Maze (Toxic Maze navigation, consecutive Wall Kicks to bypass elevator, RTA possible)
