How can I solve a 2x2x2 rubik's cube with only 2 algorithims?

Answer 1

You only need two of the algorithims needed to solve a 3x3x3 to solve a 2x2x2. Okay so first you need to solve one colored face (one side of one color). I'm gonna use white as an example. First, I would recommend getting all the pieces with white on them on one side. You have to make sure that the corners correspond though. For example, if I have the white-red-blue corner, I need to make sure that the white-blue-orange corner is next to it. Not nessecerily oriented correctly, but there none the less.(by 'oriented correctly' I mean flipped the correct way.) Once you have all the corners, you use this algorithim to flip them to be oriented properly. Ri Di R D Right inverted, Down inverted, Right, Down. Inverted meaning a counterclockwise turn. It's very simple. When I say right I mean you turn the face on your right counterclockwise, turn the bottom face counterclockwise, turn the right face clockwise, and finally turn the bottom face clockwise. IMPORTANT: YOU HAVE TO DO THE LAST STEP. SOMETIMES PEOPLE DO NO DO THE LAST TURN ON THE BOTTOM FACE. YOU NEED TO DO THIS STEP OR MESS UP THE ENTIRE THING LATER. Now you should have got the white face solved. Meaning you should have one entire face white, and the entire first layer solved. If you do great! Turn the cube over so the side you just solved is on the bottom. NOw we have to place the final corners in the correct spots but not oriented correctly. First try to find a corner already in the correct spot. If you can't find one just move the top layer until you have one in the right spot, but not oriented correctly. Hold the cube so the corner that is correctly placed corner is in the bottom left hand corner. Now here's the second and last algorithim you need. U R Ui Li U Ri Ui L Keep doing that algorithim until your corners are placed correctly. Once you have them all placed correctly, you can do the first algorithim again. Now it may look like you messed up the white face. It all magically comes together in the end. Keep doing that first algorithim until you solved all the corners. Key to doing this step is the very last turn in the algorithim. The last turn on the down side. Congrats, you should have solved your 2x2x2 cube! If not, try again. If it doesn't work a second time, try different directions.
