To solve a 3x3 Rubik's Cube using the beginner's Layer-by-Layer (LBL) method, follow these main steps:
Step 1: Complete the First Layer Cross
- Start by solving a cross on one face, typically the white face.
- Align the white edge pieces with the center pieces of the adjacent colors.
- Position the white edges correctly without disrupting the cube's other parts
Step 2: Complete the First Layer Corners
- Insert the white corner pieces to complete the first layer.
- Match the corner piece colors with the adjacent center pieces.
- Use simple algorithms or repeated moves to position corners correctly
Step 3: Solve the Second Layer
- Solve the middle layer edges by inserting the correct edge pieces between the first and third layers.
- Use algorithms to move edges without disturbing the solved first layer
Step 4: Complete the Third Layer Cross
- Flip the cube so the yellow center is on top.
- Form a yellow cross on the top face by applying specific algorithms.
- Ignore the corners for now and focus on the edges
Step 5: Position the Third Layer Edges Correctly
- Rotate the top layer to align the yellow edges with the center colors.
- Use algorithms to permute the edges to their correct positions
Step 6: Position the Third Layer Corners
- Place the yellow corners in their correct positions, regardless of orientation.
- Use algorithms to cycle the corner pieces until all are correctly placed
Step 7: Orient the Third Layer Corners
- Twist the yellow corners so they are oriented correctly.
- Apply algorithms repeatedly to orient each corner without disturbing the rest of the cube
Additional Tips:
- Learn and practice the basic algorithms for each step.
- Keep the white face on the bottom or top as instructed to maintain orientation.
- Practice the moves slowly at first, then increase speed as you get comfortable.
- Video tutorials and interactive guides can be very helpful for visualizing the steps
By following these seven steps and practicing the associated algorithms, you can systematically solve the 3x3 Rubik's Cube from any scrambled state.
