you should already know how to solve the Rubik's 3 by 3 before learning to solve the 4 by 4 but if you don't that's ok it will just take a lot longer to grasp.
Step 1: Terminoligy
Step 2: Centers
There is basic just this one move to finish this step you can do the same move backwards if the pieces are in a different order. Like this r' u' r that's if they're switched. and if you have a piece on the back of the cube and you are trying to get it to the front just do this. l B' l
so just do that a bunch of times until you have every side together.
Step 3: Are Your Centers in the Right Places?
Get BLUE on the top. then look down on one of the sides you should see Yellow then looking to the left of you yellow should see RED more to the left is WHITE more to the left is ORANGE than on the bottom should be GREEN. I like to remember the order by saying blue mustard blood milk oranges lettuce.
If they are not in that order you will have to do this move to get them in the right place.
picture will show you how to switch them. odds are it wont only be one that needs to be switched some times you might need to move al of them but if you pay attention while you make the position of the centers that will help.
ok so you have some off brand cube and that's not the right order. well look at the corners they will show you the way.
Step 4: Edge Pairing
pretty simple the only thing you have to look out for is if the top layer is paired up.
you will have to find the pieces you need. and put them in the right places this is how it has to be arranged.
So what happens if I don have 3 left to pair up? you might ask.
go to the last step called special moves you have a common error that happens only on the 4 by 4 making it a lot harder to solve with out a guide.
Step 5: Solve It!
It's now time to solve it! Since you wont be turning the mid slices for the solving you can just pretend that it's a 3 by 3 isn't that neat. so since I'm lazy and don't want to re make an instructabbleyou can use the 3 by 3's instructible!
If you already know exactly how to solve the 3 by 3with out any instructions that great just do it on your own!
The stop motion animation seen below is the stapes that will follow in order to solve the 3 by 3 looks simple doesn't it.
Step 6: Special Moves :( Not Fun
Each one takes a lot of turns to complete.
picture 1 is the one you need to do from edge pairing this one is the most frequent.
how to fix it hold it just like in the picture.

picture 2 you will figure you need to do it during the top cross.

picture 3 this one you will figure out you have it right at the end end of the solve.

BE VERY CAREFUL WHEN USING THE SPECIAL MOVES THEY MAKE IT VERY EASY TO WREAK THE WHOLE CUBE!!!!! follow them carefully...
Yay my instructable is done! I'm so happy! I hope that you all like my Instructable and find it easy to follow point things out that i need to specify more.
Step 7: How to Make Your Friends Freak.
Give them the 4 by 4 and tell them you just got it. ask them how far along they can get it and then when they fail Epicly take it from them try yourself and beat them. betting would be col too.
I know there are some people in this world that haven't seen tutorials on youtube so some people don't know how.
