THIS IS A TRUE STORY
So, a couple years ago I finally figured out how to solve a 3x3x3 Rubik's Cube. Eventually I got pretty good at it and was like "I need a new challenge," so finally a couple weeks ago I bought a 4x4x4. Watching a tutorial on it I learned that a lot of it is more intuition than algorithms, and eventually you can get it to a point where you solve it just like a 3x3x3.
But then comes a beast. Its name...... is PARITY ERRORS. Parity errors are errors that can occur on a 4x4x4 but not a 3x3x3, such as two corners being flipped or a center edge being flipped opposite of what it should be. There are REALLY long and obnoxious algorithms to solve these parity errors.
So I've got pretty much the entire cube down except for the parity errors (since like I said before it's mostly intuition and solving like a 3x3x3). Tonight I was solving my cube..... and I discover by the end that I have TWO parity errors at once! You should've seen my reaction; I was just completely floored. So I go to the same tutorial video that taught me how to solve the 4x4x4, and I solve one parity error. Boom, ok, that's out of the way. I go to solve the 2nd parity error..... and from it spawns TWO MORE, just like hydra! I WAS SO PISSED!! This hardly ever happens.... finally I solved it but you cannot begin to fathom my frustration with these parity errors.
