2x2x2 Beginner's Guide:
by: Caleb Lau
Introduction and Comparison:
Learning to solve the 2x2x2 is not a hard goal to meet. With background in 3x3x3 solving, anybody can complete a 2x2x2 cube.
Picture this: a 3x3x3 cube without any center or edge pieces.
Because I am not an expert in solving the 2x2x2, I will only provide a short beginner's guide. This guide is designed for those of you that can already solve the 3x3x3. If you need any help with that, feel free to consult my beginner's guide. Let's begin.
Method:
The method described here is exactly the same as the method described in my 3x3x3 section. In fact, it is even easier. But, just for the heck of it, I'll outline it here:
1. Solve Bottom Layer (no cross to solve)
2. Orient Top Layer Corners (no edges)
3. Permute Top Layer Corners (no edges)
Yup, that's it. Only 3 steps.
Step One: Solve the Bottom Layer:
The bottom layer may be a bit confusing for those who are not used to the fact that there is no center. (You can no longer use centers as reference points.) Because the puzzle is so much easier than the 3x3x3, I would not recommend picking and sticking to a starting color.
Okay, pic the side that has the most pieces "blocked" together. That side is now your starting side and all the properly positioned pieces are already solved. Use your knowledge of 3x3x3 solving to put the remaining (in any) corners into their proper location(s). That's it.
Step Two: Orient Top Layer Corners:
Once again, use your knowledge of 3x3x3 solving to assist you. It should pretty self-explanitory.
Step Three: Permute Top Layer Corners:
Lastly, (I know this is getting kinda redundant, but there's no better way to say it... at least not that I know of) use your knowledge of 3x3x3 solving to permute the corners. Your should be able to figure out which algorithms to apply in this step. Hint: any PLL algorithm works, just ignore the edge pieces.
Conclusion:
I hope you enjoyed this tutorial. I no it's not very detailed so if you any have questions or suggestions, please, feel free to contact me.
Happy Cubing!
