A step-by-step guide on how to solve a Rubik's Cube written by two young cubing champions, Daniel Goodman and Daniel Rose-Levine. The authors share their expertise, demystifying the process of solving the cube layer by layer. They also discuss misconceptions and introduce notation for describing moves. an essential resource for both beginners and experienced cubers.

● 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
● 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
● 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!
Edges in green
Corners in yellow
Centers in blue
On a standard cube:
Blue is opposite green
White is opposite yellow
Red is opposite orange
● 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
● 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
● 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
● 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!)
● 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’
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.
