While I was trying to solve the Rubix Cube 2x2 all by myself, found it really challenging. Then bit of help from Google and Youtube, I got the working formula and wanted to share it with everyone.
- Make sure you have 3 whites together.
- Keep the last white at the bottom row below the blank spot
White needs to be solved for top side of the cube
Formula:
R' D R D'
- Right Reverse (R')
- Down Clock wise (D)
- Right Forward (R)
- Down counter clock wise (D')
You will have to do this in a loop until the goal is obtained.
- Make the White side face top
- If you have any two colors matching on one side keep it facing away from you
White is solved and top row colors are solved.
Formula:
R' D R L' D' L R' D R
- Right Reverse (R')
- Down Clock wise (D)
- Right Forward (R)
- Left Reverse (L')
- Down Counter Clock wise (D')
- Left Forward (L)
- Right Reverse (R')
- Down Clock wise (D)
- Right Forward (R)
You will have to do this in a loop until the goal is obtained.
- Now invert the cube and keep White side facing bottom.
- If you have one yellow color keep it on bottom left on top.
- If you have two yellow close to each other then keep it on the right side
- If yellow is diagonal then make sure one of the yellow color is on bottom left.
- If there is no yellow, no problem just continue.
Yellow is solved and top row colors are solved.
Formula:
R U R' U R Ux2 R'
- Right Forward (R)
- Up Clock wise (U)
- Right Reverse (R')
- Up Clock wise (U)
- Right Forward (R)
- Up Clock wise (U), 2 times
- Right Reverse (R')
You will have to do this in a loop until the goal is obtained.
- Look for any solved side, if you have one then keep it away from you
- If you don't have solved side no problem, we can still continue.
To have all the sides solved.
Formula:
R' F R' B'x2 R F' R B'x2 Rx2 B'x2
- Right Reverse (R')
- Front Clock wise (F)
- Right Reverse (R')
- Back counter clock wise (B'), 2 times
- Right Forward (R)
- Front Counter Clock Wise (F')
- Right Forward (R)
- Back counter clock wise (B'), 2 times
- Right Forward (R), 2 times
- Back counter clock wise (B'), 2 times
You will have to do this in a loop until the goal is obtained.
Finally the algorithm goes like this
# Stage 1 : Solve for 3 colors
while NOT ( you have all white solved ) {
#Apply formula
R' D R D'
}
# Stage 2 : Solve for Top Row
while NOT ( you have all sides for white is solved ) {
#Apply formula
R' D R L' D' L R' D R
}
# Stage 3 : Solve for Bottom
while NOT ( you have yellow solved on bottom ) {
#Apply formula
R U R' U R Ux2 R'
}
# Stage 4 : Last Stage
while NOT ( you have the puzzle solved ) {
#Apply formula
R' F R' B'x2 R F' R B'x2 Rx2 B'x2
}
