Ground is a tool in Elemental Box that changes the shape of the preset walls within the game, which works similarly to the wall element. There are four variations of ground:
- Ground-U - Default Ground option. 1 horizontal wall at the bottom and 2 vertical walls at the sides of the screen.
- Ground-V1 - 1 horizontal wall at the bottom and 2 walls at each side slanted at 45°.
- Ground-V2 - 2 walls at each side slanted at about 27° meeting at the bottom slightly off-centre.
- Ground-O - Similar to Ground-U, with an extra wall at the top of the screen..
