How to Solve the Rubik’s

Cube: All 6 Sides!

Daniel Goodman and Daniel Rose-Levine

Introductions

Daniel Rose-Levine

● 16 years old, freshman at Bard College at Simon’s Rock ● From Red Hook, NY ● Cubing for 4 years ● 3x3 with feet world record single (16.96) and average (22.22) ● 1st in North America for sum of ranks

Demonstration!

Types of pieces

● A Rubik’s Cube is made up of edges, corners, and centers ● Edges have 2 stickers, corners have 3, and centers have 1

Edges in green

Corners in yellow

Centers in blue

Types of pieces

● Centers don’t move in relation to each other! ● That means, the center determines what color the side will be when solved ● That also means that opposite centers will stay the same!

Centers in blue

On a standard cube:

Blue is opposite green

White is opposite yellow

Red is opposite orange

Misconception!

● You don’t solve the first side, then the second, then the third, then the fourth, then the fifth, then the sixth ● Once you have one solved side, you’ve already made quite a bit of progress on quite a few other sides! ● Focusing on only one of those sides at a time would be extremely difficult and not particularly fast

Misconception!

● Instead, we’ll be solving layer-by-layer! ● Notice how when you have a solved side, an entire THIRD of the cube is done ● We’ll take advantage of this

Notation?

● A way of describing the moves you make on a cube ● There are six sides, so we’ll represent each side with a letter

Normally, we’ll hold the cube so we can see the U, F, and R sides

U p, D own,

L eft, R ight,

F ront, B ack

Notation!

● You can make three different turns on each side ○ One turn clockwise ○ One turn counterclockwise (same as three turns clockwise) - add a ’ ○ Two turns (same in both directions) - add a 2

“Clockwise” is based on if the side was facing us

Turning F clockwise goes in the same direction as turning B counterclockwise (this is true for all opposite sides!)

Try it out!

● We can put these moves together to create algorithms - a fancy word for sequences of moves ● Try it out by doing these algorithms! ● R U R’ U’ ● F2 B2 R2 L2 U2 D ● R’ F R F’

The first layer

White cross

Using U moves , match a white edge with its corresponding center. Then, do an F2 to move the edge to the bottom. Repeat for all 4 white edges.
