Sonic the Hedgehog Spinball/Glitches

This article contains a list of glitches from Sonic the Hedgehog Spinball. Unless otherwise noted, all glitch names are conjectural. Many of them have not been confirmed by Sega.

List of glitches
With a code, it is possible to access levels after level 5, although most (or all) of these levels are mostly unplayable messes with glitched graphics. Some feature the HUD bar at the top of the screen while others don't, most will play Sonic's death sound, and some crash upon arrival. Some of the levels that do play Sonic's death sound either:
 * 252 glitch levels:
 * Play it once only
 * act like a normal level of the game, and play it, and then "try again".
 * play the death sound multiple times at once
 * have the death sound play multiple times, and echo the sound effect.

Sometimes, when one of the latter 2 occurs, Sonic (in his death animation) will go from one side of the screen to another side/the middle, or come out the bottom and go back down. It is unknown why these levels exist, although it is possible that at one point, these "levels" were once fully playable and were scrapped without being fully removed from the game.
