The magnetic sphere[1] (ジャンプシード[2] Janpu Shīdo?, lit. "Jump Seed"), also known as simply the sphere,[1] is a gimmick that appears in the Sonic the Hedgehog series. It is a type of sphere that the player can stick to.


The magnetic spheres have varied in appearance, but they are overall spherical bodies that are about four times the size of the playable character.

In gameplay, upon contact, the magnetic spheres will make the playable character stick to them and force them into a Spin Attack. When this is done, the character will stick to the magnetic sphere, though they will rotate around it, alternating between the front and back layers. The player can also spin in the left and right directions using the assigned buttons for such actions. To get out of a magnetic sphere, the playable character has to jump; after doing so, the playable character will be launched a certain distance depending on their location on the sphere before jumping. If the character jumps at an edge of the sphere, the jump will be short; if they jump when at the center, however, they will jump a great distance. This can be used for the player to reach faraway objects or to achieve higher speeds.

Game appearances

Sonic the Hedgehog 3 & Knuckles

In Sonic & Knuckles and the lock-on game Sonic the Hedgehog 3 & Knuckles, the magnetic spheres[1] (ジャンプシード[2] Janpu Shīdo?, lit. "Jump Seed") only appear in the Glowing Sphere Stages. In these games, they appear as large spheres that glow in different colors. They also release small sparkles of electricity, but those are harmless.

Sonic Mania

In Sonic Mania and its expansion Sonic Mania Plus, the magnetic spheres appear in both Acts of Titanic Monarch Zone. In this game, they have been re-designed to resemble spherical plasma globes with a white outline. Their functionality, however, remains identical to how it was in Sonic & Knuckles. In these games, some spheres might move in a specific pattern, often in groups.
