Puzzle Inventions

Original 3×3×3 Architecture (1974)Invented by Ernő Rubik. The underlying mathematical group and mechanical axes used by our Mirror Cube simulation inherit from his original patent and design.
Mirror Blocks / Bump Cube (2006)Invented by Hidetoshi Takeji. The unique shape-shifting mechanic, achieved by off-centering the core while maintaining uniform single-color faces, is Takeji's brilliant contribution to twisty puzzles.

Algorithmic Methodology

Two-Phase Algorithm (1992)Developed by Herbert Kociemba. Our automated 3D solver utilizes ports of this exact heuristic search algorithm to compute near-optimal solutions (sub-22 moves) in milliseconds.
CFOP Speedcubing Method (1997)Popularized by Jessica Fridrich. The Cross, F2L, OLL, PLL method taught and referenced in our educational sections is the standard for modern speedcubing.
