The Mini Mirror Cube (2x2x2), invented by Katsuhiko Okamoto, is a shape-shifting twisty puzzle, a compact version of the 3x3x3 Mirror Cube. Its 8 corner pieces, varying in size, challenge solvers to align by shape, not color, with ~3.7 million combinations. Unofficial solves average 10-20 seconds. Rotate faces like a 2x2x2, using algorithms like Ortega to solve. A collector’s favorite, QiYi’s stickerless versions turn smoothly. The virtual simulator offers a fun way to scramble and solve this engaging puzzle anytime.
