It acts like a Rubik's Cube with blocked layers. Only three layers can turn, i.e. those in which the rounded "enabler" cubie resides. Specialists may call this type of turning "deeper-than-deep cut". This puzzle is sort-of the opposite of Fused Cube, where the three layers of the special corner cubie cannot turn. This puzzle was inspired by a similar design by Evgeniy Grigoriev with an unlocking edge instead of an unlocking corner, and a comment by Bram Cohen.
