• Rubik's Cube - You can do it no problem, Here is how
    102 replies, posted
[B]Rubik's cubes are a cube based puzzle in which you turn the sides to achieve the goal of making all of the sides of the cube match up, so that it appears as a cube with 6 different coloured faces.[/B] Rubik's cubes are difficult, though possible to solve without using a known method, but when a known method is used, it is often in the form of algorithms. Algorithms work by finding patterns on the cube and performing a list of moves on the cube to perform a desired move of pieces. Some of this may appear complex at the beginning, and you won't be able to do it without referring to the guide for a while, but I solved my cube the first time after 30 minutes using this method, a week later, I was able to do it in 3 minutes without referring to the guide. I can now do it in 1 minute and 30 seconds. You can too! Try watching this before and after reading how to do it, you might see the steps in me solving it. [media]http://www.youtube.com/watch?v=qLIgnIQgQIw[/media] [img]http://i41.tinypic.com/28klbus.jpg[/img] [highlight]Some Prequisites...[/highlight] So, of course you will need a Rubik's cube. I will be writing about the 3x3x3 variety. This is the original, and it's the most popular. [U]Piece Types[/U] There are three types of piece in a rubik's cube. They [I]never[/I] change to be other types of piece. [B]Edge[/B] [img]http://i44.tinypic.com/16gu8k.jpg[/img] [B]Corner[/B] [img]http://i43.tinypic.com/35hg1lc.jpg[/img] [B]Middle[/B] [img]http://i43.tinypic.com/a23aj6.jpg[/img] [U]Side Names[/U] These are used to easily describe a face which needs to be turned. [img]http://i43.tinypic.com/2urnihd.jpg[/img] [U]Algorithm Step Types[/U] All moves are a 90 degree turn of a face. U - Up R - Right L - Left D - Down F - Front B - Back A letter followed by the letter i represents that you need to turn it counter clockwise rather than clockwise. ALL FACES ARE TURNED CLOCKWISE AS IF YOU ARE FACING THEM (unless of course there is an i, then it's counter clockwise as if you are facing them - that is, if you were looking directly at that face and turned it, it would be clockwise, or counter clockwise if an i follows) So... RiDiRD Would mean you would... Rotate the right face counter clockwise Rotate the down face counter clockwise Rotate the right face clockwise Rotate the down face clockwise It appears complex at first perhaps. If you buy an official Rubik's Cube, it explains this notation to you as well, and there are plenty of other guides on the internet which you could use if you find this one is phrased in a way which you find confusing or something :buddy: [highlight]Now onto the actual solving![/highlight] This is where the fun begins. We start off with a crazy cube, all muddled and confusing. [img]http://i39.tinypic.com/2rpfw42.jpg[/img] The first thing we do it make a green cross, this should be do-able just by using your common sense, think about what will move when you rotate faces, and move things out of the way temporarily if need be. [I]Don't be afraid to move stuff temporarily to avoid it getting screwed up.[/I] The cross should also match up with the middle pieces on the sides surrounding the green side. Note how the orange/green edges matches with the orange middle piece, and the yellow/green edge matches up with the yellow middle piece. [B]EDIT: MORE INFO[/B] At request from some guy who couldn't make the green cross, more content is here: You want to move a piece like this one into place: [img]http://i41.tinypic.com/10gkzsk.jpg[/img] So you turn the face with it on until it is at the bottom like so: [img]http://i43.tinypic.com/zmip35.jpg[/img] Now keep turning the bottom layer until you find that it lines up with its colour: [img]http://i44.tinypic.com/29w0gsn.jpg[/img] Now you rotate that face 180 degrees into place and that branch of the cross is done: [img]http://i39.tinypic.com/24gq2vp.jpg[/img] Repeat this for all of the branches of the cross (don't be afraid to break part of the cross to be able to move something to the bottom layer, you can always put it back once you have put the thing in the bottom layer - rotate the face so that you get the bit into the bottom layer, rotate the bottom layer once to stop it being taken out of the bottom layer again, now rotate the face back to how it was to restore that part of the cross) When you are all finished, it will look something like this: [img]http://i39.tinypic.com/34g3jn7.jpg[/img] Next, you do the corner bits. This is done by matching up the corner pieces to below where they need to be (keep in mind that the colours need to match up on both the green face and the two faces to which it corners with). Note that in this picture, we are facing the bottom of the cube, and on the top is the green side. As you can see, we want to move it up there. This is done by using... RiDiRD This should be repeated until the piece is in place and oriented correctly (that is, the green face of the sub-cube on the green face of the rubik's cube). This could take up to 6 repeats until it's in place. [img]http://i40.tinypic.com/v2y3xg.jpg[/img] Once all the corners are done it should look something like this (note - the bottom doesn't matter, it's just the top corners and edges, the yellow/green and orange/green edges and the middle pieces being lined up that is important. You can completely ignore the bottom 9 subcubes): [img]http://i41.tinypic.com/eitnr8.jpg[/img] Flip the cube upside down. Now we do the middle edge pieces. There are 3 possible situations - [U]Front Match[/U] We want to move the piece which is now on the top layer (the yellow/orange edge - look for an edge piece which you can move into the correct place) as if we were to rotate the front face clockwise (but without the annoying side affects of completely screwing up everything else) [img]http://i39.tinypic.com/r1ftw2.jpg[/img] To move it into place, hold it as shown and do... URUiRiUiFiUF That'll move it into place. [U]Right Match[/U] We want to move the piece which is now on the top layer (the red/white edge - look for an edge piece which you can move into the correct place) as if we were to rotate the right face counter clockwise (but without the annoying side affects of completely screwing up everything else) [img]http://i44.tinypic.com/2lcva68.jpg[/img] To get it into place, hold it as shown and do... UiFiUFURUiRi That should put it into place. [U]Wrong Way Round[/U] When a piece is the wrong way round like so, just do either of the above algorithms (the right match or front match) and it will get it on the top layer for you so that you can do the right match or front match accordingly to get it into place the right way round. [img]http://i44.tinypic.com/34rulg7.jpg[/img] Right. That should give you something like this once you have done all of those edge bits. [img]http://i42.tinypic.com/2evumn5.jpg[/img] If the green side isn't complete, you need to start again because you have gone wrong. If any of the sides aren't 2/3 complete like in the image, you have gone wrong - if you think you can fix it, try, if it goes wrong, start again. Now, you see that blue pattern on the cube? There are three possible patterns you will see. Try rotating the cube to get it into the position where you can see one of the following patterns. [U]Pattern 1[/U] Top middle is blue, face-top edge is blue on the face side, right-top edge is blue on the right side. [img]http://i42.tinypic.com/2evumn5.jpg[/img] [U]Pattern 2[/U] Blue V towards the back of the top, face-top edge is blue on the face side, right-top edge is blue on the right side. [img]http://i43.tinypic.com/2ptx6iu.jpg[/img] [U]Pattern 3[/U] The Blue line going from right to left, face-top edge is blue on the face side. [img]http://i43.tinypic.com/awowft.jpg[/img] Right, so you have identified a pattern (if you haven't, you have gone wrong, try to fix it or start again), now to turn that into a blue cross on the top (note, if it's already a blue cross, then this makes things easier for you). FRURiUiFi If you started with pattern 1, this will make pattern 2. If you started with pattern 2, this will make pattern 3. If you started with pattern 3, this will make the blue cross. So now you will have a blue cross. Line up the red-blue face with the red middle like so: [img]http://i40.tinypic.com/e5int1.jpg[/img] Now we want to make the yellow blue line up while keeping the red lined up. We do so like this: RURiURUURi You may need to repeat this a few times, but when it has finished the yellow will line up like this: [img]http://i42.tinypic.com/2e6hlra.jpg[/img] Now turn to the white face. If it's orange, do this: RURiURUURi U Note: its the same as the last one we did, but with one extra up turn added in. This will give us a nice matching cross, and we can proceed to complete the cube by doing the corners. Look for a corner which is in the right place on the blue face. It doesn't need to be rotated correctly, just in the right position like this guy: [img]http://i39.tinypic.com/21lobk8.jpg[/img] If you can't find one, then do this once: URUiLiUiRiUiL You should now be able to find one which is in the right place. When you have found one, do that algorithm we just said about: URUiLiUiRiUiL Repeat until all the corner cubes are in the right place (like I said, they don't have to be oriented correctly). [img]http://i39.tinypic.com/s3nfvt.jpg[/img] Now, hold the cube. In this step DO NOT ROTATE THE CUBE AROUND IN YOUR HANDS. Keep the cube still in your hands, rotating the neccessary sides. Now, do... RiDiRD Repeat until the corner piece is rotated correctly. Other parts of the cube will look so screwed up right now. DO NOT WORRY - If you do it right, it all sorts itself out. Now, as I said, [I]do not rotate the cube[/I]. Do one U Now, repeat to solve this corner piece (if any corner pieces are solved already, just leave that piece and do another U) Do one U Now, repeat to solve this corner piece. etc. It's a loop of U, then doing the algorithm to get the corner piece oriented correctly. When they are all oriented correctly, the cube should have sorted itself out, and you should just turn the upper face until it matches up. [img]http://i41.tinypic.com/28klbus.jpg[/img] I this was your first attempt, you are probably sitting there thinking that it doesn't work and I've given bad instructions. Trust me, it takes a few tries before it all goes right. Good luck! [highlight]Bonus Content[/highlight] I found this out myself: Take your solved cube and do... UDi [img]http://i39.tinypic.com/2gxk7ic.jpg[/img] Now, rotate it counter clockwise so that what was the right face becomes the upper face. Do UDi again. Now, rotate it clockwise so that what was the upper face becomes the right face. Do UDi again. Start from the beginning of this bonus content bit, repeat, and eventually you will get this: [img]http://i44.tinypic.com/2vni3q9.jpg[/img] If you can't get it to work, try looking on youtube or something for someone elses explanation. I assure you that this works, and it's so satisfying to solve it for the first time. This is the biggest thread I have ever made, I hope it actually gets some level of popularity. It was fun for me to write anyway. Enjoy your rubik's cubing.
Using this method of solving it, anyone in the world can solve a Rubiks cube, unless you're colorblind. I solved it in 48 seconds like this once.
This is a good guide. and cubes are still to hard for me.
[QUOTE=Zoook;15180967]Using this method of solving it, anyone in the world can solve a Rubiks cube, unless you're colorblind. I solved it in 48 seconds like this once.[/QUOTE] Nice. In the video I showed I actually used a modification called the keyhole method which allows you to solve the middle layer edges much faster. You really need to know this method first though, after you know it well you can look up the keyhole method on youtube.
Nice guide...maybe I'll try and solve the cube I've got. If I can even find it, that is.
I just peel off the stickers and put them all the way they should. Beat that.
[QUOTE=MR-X;15181140]I just peel off the stickers and put them all the way they should. Beat that.[/QUOTE] Turn the top face 90 degrees, pull the corner off, take it apart and put it back together again solved. Also, if you put it together wrong it acts as a funny unsolveable prank cube.
Cool thread, my phone can solve Rubik's cubes.

You should've taught Petrus, that's what I teach everyone that asks me how to solve a cube and they can get them in ~30 secs. I then pull out my 7x7x7 and blow their minds :D You should show how to solve wierd shape cubes, I still can't finish my Square-1 (Cube 21). [editline]09:48PM[/editline] Also, include a link to a place where you can buy speed cubes, those are SUPER fun to dick around with. [editline]09:53PM[/editline] You can also get sticker replacements from this link [url]http://cubesmith.com/[/url] the best to get are the tiles.
[QUOTE=h2ooooooo;15181303][url]http://www.wrongway.org/cube/solve.html[/url][/QUOTE] Wow, that's pretty cool. I looked up the Keyhole method. I should be able to get that down pretty quickly. And for anyone that would like to learn how to solve a Rubik's cube, but doesn't have one, you can download this program and learn on it. [url]http://www.gabbasoft.com/download.htm[/url]
[QUOTE=Anonymouse;15181365]You should've taught Petrus[/QUOTE] I wasn't familiar with that. I'll look at it tommorow, since it's time for me to get some sleep now.
That's one of the most common ways to solve a 3^3 I used to have some cheap knock-off cube. I solved it a few times, then it fell apart. I plan to get a larger, more sturdy cube eventually.
I used to solve with this method, But now I use a different type. I got my time down to about 35 seconds with this method, but Then you hit a wall.
I admire the drawing skills. Beautiful tutorial.
Too bad I threw out my rubiks cube last week because I couldn't solve it. Argh.[img]http://d2k5.com/sa_emots/emot-argh.gif[/img]
I can't make the green cross D:
Actually, instead of Petrus, go for the Fridrich, that's what the fast people use.
Been speedcubing for about 2-3 weeks now and got my time down to 42.15. One of my friends fastest time is 15.72. Going to a competition with him on June 13th. [editline]07:08PM[/editline] [QUOTE=Anonymouse;15182639]Actually, instead of Petrus, go for the Fridrich, that's what the fast people use.[/QUOTE] Agreed. I use Fridrich for F2L then I use 2-look OLL and 2-Look PLL
For anyone who can't do it, the guide that comes with the official Rubik's cube has a piss-easy guide on how to do it. It's not fast by any means, but you'll easily be able to learn within 1-2 hours.
Oh, I thought these things made a comeback in my area. Guess not. Thanks for the guide! Guess I'm joining the bandwagon.
Cool man, I'll try it out tomorrow.
I practiced for like a day or two, and now I can do rubiks cubes pretty damn fast, I'm still working on it speed, and my cube is kind of fucked up though :/ [QUOTE=Jallen;15181168]Turn the top face 90 degrees, pull the corner off, take it apart and put it back together again solved. Also, if you put it together wrong it acts as a funny unsolveable prank cube.[/QUOTE] I accidentally did this to myself trying to solve the cube to fast, and was pissed off.
Great tutorial! My cubebis finally fix

I just learned to solve Rubik's Cubes yesterday actually, from a tutorial on Youtube.
Hopefully this thread helps me solve one, I never have before :frown:
