Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Erno Rubik. It's originally called the "Magic Cube"

The Rubik's Cube can be very frustrating and may seem next to impossible to solve ... However, one can solve the Rubik's cube with few algorithms in hand.

I have a step by step approach for the beginners to solve the regular 3x3x3 Rubik's cube. Before trying to solve the Rubik's cube, lets examine the cube.

The cube contains six sides one colour on each side.
The cube contains three different pieces as mentioned below:
  • Center piece: this contain one colour at the center of each face and determines the colour of the face.
  • Edge piece: this contain two colours connecting two faces of the cube.
  • Corner piece: this contain three colours connecting three faces of the cube.
Based upon how we hold the cube, we call the six faces of the cube as
  • Front face (F)
  • Right face (R)
  • Left face (L)
  • Back face (B)
  • Top face (T)
  • Bottom face (D)
Lets see the notations we use in our algorithms - taking front face as an example
  • F - Front face clock wise 90 degrees rotation.
  • Fi - Front face anti-clock wise 90 degrees rotation
  • F180 - Front face close wise 180 degrees rotation
  • Fi180 - Front face anti-clock wise 180 degrees rotation

Before start solving 3x3x3 Rubik's cube, just mess up the cube.

Now start solving the cube with below steps
  • Step1: Solve White cross
  • Step2: Solve Complete white face
  • Step3: Solve Middle layer
  • Step4: Solve Top yellow cross
  • Step5: Solve Complete top yellow face
  • Step6: Solve Top layer, corner pieces
  • Step7: Solve Top layer, edge pieces .... Now the Rubik's cube should have been solved.
