What This Algorithm Does
This algorithm places a corner piece into the first layer (bottom layer) in its correct position and orientation. This is the first step of the Layer-by-Layer method.
Recognition Guide
How to use this algorithm:
- Choose a corner piece that belongs in the first layer
- Position it above where it needs to go
- Orient it so the bottom color faces down or to the side
- Execute the algorithm to place it correctly
Cube Orientation: Hold the cube with the first layer (your chosen color) on the bottom.
For Kids 👶
The first step in solving the cube is to put the corner pieces in the bottom layer. Think of it like building the foundation of a house - you need to get the corners right first!
Find a corner piece that has the color you want on the bottom. Move it above where it needs to go, then do the moves: Right-Up, Right-back, Up-back, Right, Up, Right-back.
This will put the corner in the right place! Do this for all four corners of the bottom layer.
For Adults ⚡
The first layer corners algorithm is fundamental to the LBL method. It uses a simple sequence to insert a corner piece into the first layer while preserving already-solved pieces.
Algorithm: R U R' U' (repeat as needed)
Execution: This algorithm uses a 3-cycle pattern. Position the corner above its target location, then execute the sequence. You may need to repeat it 1-3 times depending on the corner's orientation.
Key Concept: This algorithm teaches the fundamental principle of preserving solved pieces while inserting new ones - a concept that carries through to more advanced methods.
Algorithm
R U R' U'
Note: You may need to repeat this sequence 1-3 times depending on the corner's orientation.

Common Mistakes
- Wrong orientation: Make sure the corner is positioned correctly before starting.
- Breaking solved pieces: Be careful not to move the cube in a way that messes up already-solved corners.
- Not repeating enough: If the corner isn't placed correctly, repeat the algorithm.
- Rushing: Take your time to understand how each move affects the corner piece.
