Deeper-than-origin Prism is arguably the simplest deeper-than-origin twisty puzzle. Whereas its mechanism is not deeper than origin cut
, it operates like a deeper-than-origin puzzle. The big triangular part at the bottom acts as core. There are two types of moves possible: 1) turn the square side face by 180 degrees, and 2) turn the top two triangular faces by 120 or 240 degrees. The second move is a deeper-than-origin move, as its cut plane is below the origin. The geometry of this puzzle may also be seen as the simplest of the Bram's Sphere set of geometries
, this one being (2,3, 1/2)
