This article contains a list of glitches from Sonic & Knuckles Collection. Unless otherwise noted, all glitch names are conjectural. Many of them have not been confirmed by Sega.
List of glitches
- Frozen Time in Launch Base Zone:
The timer does not resume at the second boss of Launch Base Zone Act 2. As such, the player cannot activate their Super State while fighting the boss (or even the third boss in Sonic the Hedgehog 3 alone).
- Angel Island Skip:
To do this glitch, the player needs Tails. Tails has to carry Sonic up then stop flying. If the player has Hyper Sonic, they can double jump through the dirt. They can skip the mini-boss if the game is Sonic the Hedgehog 3. However, if the game is Sonic the Hedgehog 3 & Knuckles, they will fight two Dr. Robotniks.
- Carnival Night Underwater:
The player should get to the place where Knuckles shuts the lights off. They should then have Tails lift the barrier you just went through. If they keep on going backwards, they will find themselves in Carnival Night underwater.
