Understanding the Rubik’s Cube
The Rubik’s Cube is a three-dimensional puzzle invented in 1974 by Hungarian sculptor and professor Ernő Rubik. It consists of 26 smaller cubes arranged in a 3x3x3 cube with each side covered by a different colored sticker. The objective of the puzzle is to manipulate the cube to align the colors on each side, forming a solved state.
Getting Started
Before attempting to solve the Rubik’s Cube, it’s essential to understand its basic structure and terminology.
- Centers: The six central squares of each side remain stationary throughout the puzzle.
- Edges: The twelve pieces connecting two centers belong to two sides.
- Corners: The eight pieces connecting three centers belong to three sides.

Ernő Rubik’s Invention of the Puzzle Cube
In 1974, Hungarian architect and professor Ernő Rubik invented the Puzzle Cube, originally called the Magic Cube. Rubik’s aim was to create a three-dimensional object that could be manipulated and that would return to its original shape.
The puzzle cube consists of a 3x3x3 cube with 26 smaller cubes, or "cubies," arranged on each side. Each side of the cube can be rotated independently, allowing for a vast number of combinations. The goal of the puzzle is to scramble the cube and then return it to its original solved state.
Rubik spent years perfecting the design of the cube and obtaining a patent. In 1980, Seven Towns Ltd. licensed the puzzle and began distributing it worldwide as the Rubik’s Cube. The toy quickly became a global phenomenon, selling over 350 million units worldwide and inspiring numerous variations and spin-offs.
Speedcubing Techniques for Rubik’s Cube
Speedcubing refers to the practice of solving the Rubik’s Cube as quickly as possible. Here are some key techniques used by speedcubers:

- F2L (First Two Layers): Completing the second layer by inserting the remaining corners and edges.
- OLL (Orientation of the Last Layer): Orienting the last layer’s corners correctly.
- PLL (Permutation of the Last Layer): Permuting the last layer’s corners and edges.
- Finger Tricks: Using specific finger movements to efficiently manipulate the cube.
- Look-Ahead: Planning future moves while solving the current step.
- Intuitive Solving: Using pattern recognition and logical deduction to solve the cube without memorizing algorithms.
