The Ice Mine takes the form of iron balls made entirely of light blue ice, both as an icon and on the tracks.
In gameplay, the Ice Mine can only be obtained at random from Item Boxes by Amy, Chaos, Ice Slicer Jet, Nutcracker Silver, Slugger Sonic, Sonic (also as Super Sonic) and Tidal Wave. As with most other Items, Metal Sonic can also use the Ice Mine if he uses the Steal Item to steal it from the aforementioned users.
Once obtained, the player can utilize the Ice Mine by pressing its icon on the bottom of the HUD. When used, the Ice Mine will drop its icy iron balls some distance ahead of the user's current location on all the lanes that the user is not currently on. If a character, including the user themselves, touches one of these icy iron balls, they will lose Rings and be frozen. To avoid the Ice Mine, the playable character must either jump over its icy iron balls or run in-between them.
The Ice Mine can also be upgraded by leveling most users up to level 4, 10 and 16 respectively. However, Super Sonic's Ice Mine is upgraded differently, being upgraded when leveling him up to level 3, 7 and 11 respectively. For each upgrade, the freeze effect of the Ice Mine will last longer.
