A 4x4x4 piece swap that showing the permutations of paired pieces to reveal parity problems to novices.
This 4x4x4 arises from piece swaps between black-bodied and white-bodied versions of a commercial cube (YuXin UnicornKing). Removing stickers from one gave a "Checker Cube / Chess Cube / Checkerboard", see the separate entry.
Leaving the other stickers created this puzzle where the body colour assists the novice to avoid the parity problems and the related frustration.
For edges this does not simplify the puzzle. For centres, the body colours help the novice to avoid problematic permutations without the additional orientation constraints of the Super 4x4x4, see the separate entry.
This is part of the inventor's aim to simplify existing puzzles to provide stepping stones for novices looking to develop their solving skills.
This concept was implemented for the first time with a higher order cube, namely the "7x7x7 Illusion Cube with two colour corners (stickered)"
