Boss Challenge is a mini-game from The Legend of Zelda: Ocarina of Time 3D. The Boss Challenge menu can be accessed by examining Link's bed in his house. In Boss Challenge mode, Link can fight any of the eight bosses of the game's dungeons; Link is only able to battle bosses whom he has already defeated in the current save file, and neither Ganondorf nor Ganon may be fought.
When Link is in battle, a timer will record just how quickly Link is able to defeat a boss. The amount of times Link has defeated each boss is also recorded. When fighting a boss, Link will only have the necessary equipment to defeat the boss along with a bottle containing a restorative substance, such as Lon Lon Milk or a Red Potion. This bottle does not appear in Master Quest.

Once Link has defeated every boss in Boss Challenge at least once, he has the option to play a gauntlet, which is a series of consecutive fights against each of the eight bosses. When starting the gauntlet, Link will have five Heart Containers, a full Magic Meter, and the equipment necessary to defeat each boss: the Fairy Slingshot (with a full bullet bag of 30 seeds), an empty Bomb Bag (with a maximum capacity of 20), the Megaton Hammer, the Hookshot, the Lens of Truth, the Boomerang, the Fairy Bow (with a full Quiver of 30 Arrows), the Kokiri and Master Swords, all available Shields, all available Tunics, and the Goron's Bracelet. Technically, the Longshot was used against Morpha in the original battle, but the Hookshot is enough to reach the nucleus. The number of times the gauntlet is beaten and the best time is also recorded.
Upon defeating each boss, two chests will appear, a large and a small one. Inside these chests are various equipment that can be used against later bosses such as Bombs or another Heart Container, or some other objects that are useless in battle such as an Empty Bottle. However, since Twinrova is the final boss of the gauntlet, she does not leave behind any chests. Link can only choose one chest, while the other one will open and empty itself out. The items revealed are random each time Link opens the chest, and below is a chart of any possibilities.
|Boss||Large chest content||Small chest content|
|Queen Gohma||Deku Stick or Deku Seeds||Bombs|
|King Dodongo||Empty Bottle, Recovery Heart or Deku Nuts||Empty Bottle or Heart Container|
|Barinade||Deku Nuts or Empty Bottle||Empty Bottle or Heart Container|
|Phantom Ganon||Heart Container or Recovery Heart||Big Quiver, Empty Bottle or Longshot|
|Volvagia||Recovery Heart or Blue Potion||Big Quiver, Hover Boots or Longshot|
|Morpha||Arrows or Poe||Heart Container or Hover Boots|
|Bongo Bongo||Deku Nuts||Heart Container or Red Potion|
