Introduction to Speedcubing

Speedcubing is the competitive practice of solving a Rubik's Cube in the shortest time possible. The current world record is under 4 seconds! It's a thrilling combination of memory, dexterity, and strategy.

The CFOP method (Cross, F2L, OLL, PLL) is the most widely used for speedcubing. It involves solving the cube in layers, starting with a cross, followed by the first two layers, orienting the last layer, and then permuting it.

Lookahead is a technique where cubers plan their moves in advance while executing another. This minimizes pauses and speeds up the solving process. It's crucial for top-level speedcubers aiming to break records.

Finger tricks are essential for speed. Efficient turning techniques reduce the number of moves needed and increase speed. Practicing specific algorithms for different cube states enhances overall efficiency and speed.

In theoretical quantum computing, solving a Rubik's Cube could be instantaneous. Quantum algorithms can potentially solve complex puzzles exponentially faster than classical methods, though practical applications are still in development.

Some speedcubers can solve a Rubik's Cube blindfolded by memorizing the cube's state and executing the solution without sight. The current record is under 15 seconds!
