Rubik's Cube Algorithm Rianna Richardson

Rubik's Cube Facts 43, 252, 003, 274, 489, 856, 000 different configurations, and only one solution • There are • At the World's Rubik's Cube Championship people solve the cube blindfolded or with one hand • The youngest person to solve the cube was 3 year old from China Lets Give It A Go

Basic Cube Notation • R= Right Face Hint: Before starting, play with the cube to learn how it rotates. The • L= Left Face more comfortable you are the easier the following solution will • B= Back Face be. • D = Down Face • F= Front Face • U = Upper Face A letter by itself = Turn face 90° clockwise A letter + apostrophe = Turn face 90° counterclock wise A letter + 2 = Turn face 180°

The First Layer 1. Form the White Cross – Go edge by edge – Can’t mess up what you’ve already done – Edge flipped the wrong way: • R’ U F’ U’ If your cube looks like this, MOVE ON!

The First Layer 2. Solve the White Corners – Find a corner piece on B, that belongs on U • R’ D’ R D (up to five times, until solved) – If corner is on U already, but in wrong position • Hold cube sp the piece is on the upper front right position • R’ D’ R D Do this for every corner!

Move On When…. Next Step… The Middle Layer

The Middle Layer 1. Put the white face on the Bottom 2. Find the Blue/ Red piece so the Blue lines up. Or, If you See this… D L D' L' D' F' D F D L D' L' then D L D' L' D' F' D F

The Final Layer. Orient the edges - Place white side on the Bottom - 4 Possible States **The face in the pictures is U** State 4: Do algorithm for state 2 or 3, then you will be in state 2 or 3. State 2: F U R U' R' F' State 3: State 1: Ready to move on! F R U R' U' F'

The Final Layer. Permute the corners • two adjacent LL corners need to be swapped – Place white side on bottom, and corners to be swapped @ front top right and back right top – L U' R' U L' U' R U 2 • two diagonal LL corners need to be swapped – Do the above algorithm twice

The Last Layer. Orienting the LL Corners • There are 8 possible states. – State 1 (where the corners are correct) • SKIP THIS STEP! State 2: Twist three corners anti-clockwise R' U' R' U 2 R U 2 State 2: Twisting three corners clockwise R U R' U R U 2 R' U 2

The Last Layer. Orienting the LL Corners States 3 -7: If you see this do one for the following: **Hint: Figure out - Algorithm for State 1 twice intuitively, so this - Algorithm for State 2 twice becomes natural** - Algorithm for State 1, then State 2

The Last Layer. Permute the edges • 5 possible states – State 1: Edges are correct • YOU ARE DONE!! State 2 : R 2 U' F B' R 2 F' B U' R 2 State 1: R 2 U F B' R 2 F' B U R 2 States 3 and 4: Apply algorithm from State 1 or 2. Then your cube will look like State 1 or 2, apply the corresponding algorithm.

Congratulations! IT'S OVER!
