Levels that are a sequel of other ones or are heavily inspired by these ones. They can be usually identifiable with the signature "v2", "v3", "X" etc. after the name of the level. This trend has launched by Neptune, who remaked all the main levels until ToE II.

Note that Nine Circles Levels have been overlooked in this list, except for Ultra Circles levels, Moonlight, Nine Circles XII and Catastrophic (obvious remake of Problematic).
