Deep Penta looks like a simple pentagonal twisty puzzle but it is not. The design of this puzzle toy was inspired by the “deeper-than-origin” discussion at the Twisty Puzzles Forum, triggered by David Pitcher’s RotoPrism 2. The purpose of the big hole in one of the corners is to show that the mechanism of the puzzle is deeper-than-origin. However, only two deeper-than-origin rotations are enabled (two screws at the inside). Some shallow rotations are enabled too (screws visible at the outside), but not all. This makes the puzzle confusing to solve, as sometimes rotations are blocked. The screws are kept visible to reduce that confusion again.
The puzzle turns smoothly and the special features of this puzzle toy is the deeper than the origin mechanism inside. The core stays in place even if you turn parts of the cube. There is something paradoxical about “deeper-than-origin”. This puzzle is deeper-than-origin, because only some of the cuts are deeper-than-origin.
