# Basic knowledge

• Centers
• Edges
• Corners

## Methods

• We learn the Beginner Method
• An advancement of the Beginner Method is the Fridrich-Method
• We learn 6 Algorithms in the Beginner Method
• In the Fridrich-Method you learn up to 100 Algorithms

# Notation

## What is the notation?

• Description of a rotation of one side
• Is required to perform algorithms
• Also required to scramble the cube
• The whole solution is based on the notation

# Cross

## What is the Cross?

• First step
• The first time, we make it on white
• The Cross-Edges need to be correct on both sides

## Procedure

1. Search the matching edge
2. Turn the edge below the target
3. Turn up the Edge
4. If the Edge is twisted incorrectly-> F U' R U'

## Example

Scramble: L2 F2 U' F2 D B2 F2 D2 L

The white-orange Edge is already in the top layer -> U

In the bottom layer, there is the White-Green Edge.

This Edge must go below the Green Center -> D2

And has to be turned to the top layer-> F2

In the bottom layer there is the White-Red Edge.

This Edge must go below the Red Center -> D'

And has to be turned to the top layer -> F2

The last Edge (White-Blue) is placed on the red side

This Edge must turned down to the bottom layer  -> F

Afterwards the Edge has to go below the blue center-> D

Because we moved the White-Red Edge, it has to go back up again -> F'

And now, the White-Blue Edge can be turned up -> F2

## Exercises

• Cross on the Yellow-Side
• Cross on the Red-Side
• etc.

# First Layer

## What is the First LayeR?

• Whole site correct
• For this step, the Corners need to be inserted

## Procedure

1. Search the correct Corner
2. Turn Edge below its target
3. Perform Algorithm -> R' D' R D
4. As long as the Corner is correctly inserted

## Exception

Is a corner already in the top layer, you have to perform the Algorithm ( R' D' R D ) once.

## Exercises

• Solve five times one side
• The colour is arbitrary

# Second Layer

## What is the Second Layer?

• Two Layers need to be arranged correctly
• For this step, we need to insert 4 Edges
• Two algorithms are required
• The Cube has to be turned upside-down

## Procedure

1. Search an edge in the Top Layer
2. Turn the Edge to the correct position
3. Determine Case
4. Perform the according algorithm

## Search an edge in the top-layer

We search a non-yellow side in the top-layer

## Turn the Edge to the correct Position

• The bottom side of the edges has to match the colour of a center
• Only U-Moves are required

U'

## Determine Case and perform algorithm

To the Left

To the Right

U R U' R' U' F' U F

U' L' U L U F U' F'

## Learn Algorithms

• Search patterns
• Repeat

(U' L' U L) (U F U' F')

(U R U' R') (U' F' U F)

## Exercises

• Memorize the algorithms
• Solve the Second Layer till you feel safe about it

# Last Layer Cross

## Only Algorithm for this step

(F R U) (R' U' F')

• Cross on the last layer
• We have to regard the edges only
• There is just one algorithm for this step

## Determine Case and perform algorithm

Dot

L-Shape

Line

Alg -> L-Shape

2 times Alg

Alg

(F R U) (R' U' F')

# Last Layer edges

## Overview

• Orienting the Edges
• We have to regard the edges only
• There is just one algorithm for this step

## Only Algorithm for this step

(R U R') U (R U2 R') U

## Determine Case and perform algorithm

Alg -> 2 adjacent correct pieces

Place the two correct pieces at the back left + Alg

Hint: Sometimes you have to turn the U-Layer a couple of times (maximum 3 times) to see if there are 2 adjacent correct pieces.

# lAST LAYER CORNERs

## Overview

• After this last step, ther corners will be permutet and orientet correctly.
• We have to regard the cornes only
• 2 Algs are required to perform this step

## Required Algorithms

(U R U' L') (U R' U' L)

Corner Permutation Algorithm

Corner Orientation Algorithm

R' D' R D

## Corner-Permutation

One correct corner

No correct corner

You have to look around the whole cube to see if there is a correctly placed corner.

Correct corner on the front-right

U R U' L' U R' U' L

U R U' L' U R' U' L

<-- One correct corner

## Corner-Orientation

1. Get an incorrectly twisted corner to the front-right
2. R' D' R D till the corner is twisted correctly
3. Repeat till the cube is solved

Congratulations!
