So, you want to know how to solve a 2x2, eh?
Well, if you follow these steps, you'll be there in no time! Let's get started
DISCLAIMER: My 2x2 happens to have black instead of white, don't let that get you confused :D
Step 1: Starting Out
First, just scramble it up. I usually try to get it where each side has no matching colors next to eachother
Step 2: Getting the Black(white) Side
To get the black(white) side matched up. You have to take each piece that has black(white) and connect it with another piece that has the same color like it shows above.
Step 3: The Yellow Side
You'll most likely have one yellow cube on the top, if you don't skip to the third paragraph
--end of picture 1
Now line it up with its correct sides as it shows in picture 2
--end of picture 2
Then, you will use this algorithm: R, U, RI, U, R, U2, RI. Then organize the cube like you did above and keep using this algorithm until the top is all yellow.
--end of picture 3 and 4
Step 4: Fixing the Corners
Now, you will take a completed side like Picture 1. If your completed tiny cubes are diagonal from each other use this algorithm until they are next to each other: RI, F, RI, B2, R, FI, RI, B2, R2.
After they are matching, put the two matching sides to the back of the cube and do the same algorithm until you complete the cube :)
Step 5: Celebrate
Now what you want to do it take a really weird selfie, like the example my friend has given me.
Anyways, congrats. You solved the 2x2. Are you ready for the 3x3? Check my instructable on it!
