Rubik's Cube Auto-Solver

The Rubik's Cube was invented in 1974 by Hungarian architecture professor Ernő Rubik, who originally built it as a teaching model to help explain 3D spatial transformations to his students. It became the best-selling puzzle toy in history after its international release in the early 1980s. A standard cube has 6 faces, each covered by 9 stickers, and is built from 26 movable pieces (cubies) plus a hidden internal core, since the very center of the cube has no physical piece. Despite its simple appearance, the number of distinct configurations reachable by twisting its faces is astronomically large, and finding an efficient solution requires either memorized algorithms or a search over that enormous state space. Competitive "speedcubing" has turned solving it into a sport, with solvers using structured methods and cube notation to describe and execute moves precisely.

• Invented in 1974 by Ernő Rubik in Budapest, Hungary; originally called the "Magic Cube."
• A classic 3x3x3 cube has about 43 quintillion (4.3 × 10^19) possible permutations.
• "God's Number" is 20 — every solvable scramble can be solved in 20 moves or fewer using face turns.
• The cube consists of 26 visible cubies (8 corners, 12 edges, 6 centers) around a hidden core mechanism.
• Each of the 6 faces shows 9 stickers, for 54 stickers total across the whole puzzle.
• Popular solving methods include beginner layer-by-layer, the advanced CFOP method (Cross, F2L, OLL, PLL), and Roux.
• Standard move notation uses letters for each face: F (front), B (back), U (up), D (down), L (left), R (right), with a prime (') meaning counter-clockwise.
• Elite speedcubers now solve the cube in the sub-4-second range, with official world records dipping to roughly 3 seconds.
