I devised a method for beginners to solve the 2x2 without having to learn many algs. The method consist in intuitive moves and just one trigger and one simple and finger-tricky EG alg.
My intention here is not to teach an advanced method to someone that can already solve the 3x3, but spread a simple way of solving the 2x2 for kids or people that have trouble memorizing complicated algs and methods and just want the cube solved without worrying about times. Obviously, it can be extended to an advanced method afterwards.
TL;DR Teach your kids, friends or anyone else you know this simplified 2x2 method and make them have the joy of solving their first puzzle!
-Tutorial-
Algs used:
EG alg: (R U' R') (L' U L) (R U' R')
Sexy move: R U R' U'
- Step 1: Make a side
Intuitive, choose a color that is almost solved if possible
- Step 2: Permute bottom side
| When you apply the EG alg you swap two corners in the bottom layer
2.1. Skip this step if the bottom layer is solid
2.2. If you have just one bar, put the bar in the back and apply the EG alg
2.3. If you have no bars apply the EG alg and go to step 2.2
(For step 2.3 you can alternatively apply this simple alg: R2 F2 R2)
- Step 3: Orient the opposite side
First things first, you have to know which color is the "opposite side". To find this, identify the color that appears 4 times in the opposite layer. That color is the one that must be oriented
Put the layer that must be oriented facing down, and use the sexy move to point down every wrong corner in the front/right position
How to:
| Every two sexy moves applied change the orientation of the front/right corner clockwise.
After you correct one, do D moves to place another bad corner in the front/right position
Do it until all bottom corners are facing down.
- Step 4: Permute the last layer
Having one layer and the opposite side done, you have to permute the last layer. To make this put the solid layer facing up
4.1. If you have just one bar, put it the bar in the left, apply the EG move, do a D turn, and apply EG move again
4.2. If you have no bars, apply EG move, do a D2 and apply EG move again.
- Step 5: Make the last move to align both layers if necessary and...
Congratulations, you're done!
