The method presented here divides the cube into layers and you can solve each layer applying a given algorithm not messing up the pieces already in place. You can find a separate page for each one of the seven stages if the description on this page needs further explanation and examples.
Watch the cube being solved layer-by-layer with this method:
It fixes the white edges, corners then flips the cube to solve the second layer and finally completes the yellow face.

If you get stuck or you don't understand something, the online Rubik's Cube solver program will help you quickly fix your puzzle. All you have to do is input your scramble and the program will calculate the steps leading to the solution.
Use this stage to familiarize yourself with the puzzle and see how far you can get without help. This step is relatively intuitive because there are no solved pieces to watch out for. Just practice and don't give up easily. Try move the white edges to their places not messing up the ones already fixed.
Until this point the procedure was pretty straight forward but from now on we have to use algorithms. We can forget the completed white face so let's turn the cube upside down to focus on the unsolved side.
In this step we are completing the first two layers (F2L). There are two symmetric algorithms we have to use in this step. They're called the Right and Left algorithms. These algorithms insert the Up-Front edge piece from the top layer to the middle layer while not messing up the solved white face.
If none of the pieces in the top layer are already lined up like in the images below, then turn the top layer until one of the edge pieces in the top layer matches one of the images below. Then follow the matching algorithm for that orientation.
After making the yellow cross on the top of the cube you have to put the yellow edge pieces on their final places to match the colors of the side center pieces. Switch the front and left yellow edges with the following algorithm:
Turn the top layer only to move another unsolved yellow piece to the front-right-top corner of the cube and do the same R' D' R D again until this specific piece is ok. Be careful not to move the two bottom layers between the algorithms and never rotate the whole cube!
I'm already quite good at juggling with 3 balls, I know a few tricks. I can also solve a Rubik's cube. I've seen some posts containing videos of people doing it and I've seen them on YT as well, so it's obviously possible to do. I'm going to learn solving only one cube at a time right now.
Do you guys have any tips/ideas how to make this whole process easier? Is failing the only way to learn doing it? How's your experience with juggling with not so usual things?
She asked if it was common for people to solve a Rubik's cube using outside help and I said "Yeah, that's what everyone does." I didn't think it was reasonable to expect anyone out there manages to figure out how to solve one on their own. She on the other hand felt someone with genius-level spatial reasoning could figure it out on their own, like relatively quickly.
What do you all think? Does anyone out there learn how to solve a Rubik's cube without help or can we assume most people seek out the algorithms to solve what they can't figure out on their own? I suppose someone out there had to figure out how to do it but assumed it was only a select few and it would have taken a very long time to develop reliable algorithms.
I'm a beginner and I can solve it under 1:20 min with LBL method. I'm now trying to learn the CFOP method so I can improve and tbh Im feeling kinda demotivated after learning the beginner F2L, it ruined my overall time and it takes me more than 2 minutes to solve it. Anyways I was curious, how long did it took you guys to solve it under 30s?
Spend some time playing with the puzzle to familiarize with it before you read this solution tutorial and see how far you can get without help. Most people can solve one face after spending some time with the cube.
Solving the first face of the Rubik's Cube is relatively easy because there are not too many solved pieces that you can mess up.
Spend some time playing with the puzzle and try to do this without reading further this page.
We already know that the center pieces are fixed and they define the color of each face. This is why we have to solve the white edges according to the color of the center piecess as illustrated above.Solving the white edges is intuitive and quite easy because at this stage there are no solved pieces that we can break. In most cases you can just simply rotate each piece where they are supposed to be.
This is another easy stage where you shouldn't memorize any algorithm just follow your instincts. If you have difficulties solving the white corners, here's an easy trick you can always apply, you just have to memorize a short algorithm and repeat it until the piece is solved:
Play the animation for an example where the sequence is repeated five times. Watch the affected white corner going to the top then back to the bottom in each step, changing its orientation.
The sixth would bring the cube back to its original position:
In the fourth step we want to form a yellow cross on the top of the cube. Don't worry if the side colors don't match the side centers because we will send the pieces to their final positions in the next step.
We solve the yellow edges on the top of the Rubik's Cube in two steps:
First we orient them to form a yellow cross on the top, then we swap the pieces to match them with the side colors.
In some cases two opposite pieces have to be swapped which needs to be done in two steps.
Perform the algorithm once, then rotate the cube to make sure you are changing the right pieces in the second round:
We are very close to finish solving our Rubik's Cube.
At this point only the yellow corners remained unsolved which we are going to sort out in two steps.
First we have to relocate them and we'll orient them in the next and final step.
When you reach this point in the solution look for a corner piece which is in the right place. If you found one then reorient the cube in your hands so this specific piece is on the OK position and perform the formula. In some cases you have to execute it twice.
In the last step every piece is where it's supposed to be, but the yellow corners are oriented wrong.
To complete our cube we will use the same algorithm we used to solve the first layer corners but with a little trick:
Start by holding the cube in your hand having a misaligned yellow corner in the highlighted Front-Right-Up spot (see image).
Repeat the R' D' R D algorithm until this piece comes to the correct position with the yellow sticker upwards.
Turning only the Up face, move another wrong yellow corner to the highlighted spot and repeat the R' D' R D algorithm until that yellow piece is oriented correctly.
Move other misaligned yellow corners to the marked spot one by one and do the formula until all corners are solved.
The Rubik's Cube is a 3-D combination puzzle originally invented in 1974[2][3] by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube,[4] the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978,[5] and then by Ideal Toy Corp in 1980[6] via businessman Tibor Laczi and Seven Towns founder Tom Kremer.[7] The cube was released internationally in 1980 and became one of the most recognized icons in popular culture. It won the 1980 German Game of the Year special award for Best Puzzle. As of March 2021[update], over 450 million cubes had been sold worldwide,[8][9][needs update] making it the world's bestselling puzzle game[10][11] and bestselling toy.[12] The Rubik's Cube was inducted into the US National Toy Hall of Fame in 2014.[13]
On the original classic Rubik's Cube, each of the six faces was covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. Some later versions of the cube have been updated to use coloured plastic panels instead, which prevents peeling and fading.[14] Since 1988, the arrangement of colours has been standardised with white opposite yellow, blue opposite green, and orange opposite red, and the red, white, and blue arranged clockwise in that order.[15] On early cubes, the position of the colours varied from cube to cube.[16]
An internal pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be returned to have only one colour. It has inspired other designers to create a number of similar puzzles with various numbers of sides, dimensions, and mechanisms.
Although the Rubik's Cube reached its height of mainstream popularity in the 1980s, it is still widely known and used. Many speedcubers continue to practise it and similar puzzles, and compete for the fastest times in various categories. Since 2003, the World Cube Association (WCA), the international governing body of the Rubik's Cube, has organised competitions worldwide and recognises world records.
In March 1970, Larry D. Nichols invented a 222 "Puzzle with Pieces Rotatable in Groups" and filed a Canadian patent application for it. Nichols's cube was held together by magnets. Nichols was granted U.S. Patent 3,655,201 on 11 April 1972, two years before Rubik invented his Cube.
After the first batches of Rubik's Cubes were released in May 1980, initial sales were modest, but Ideal began a television advertising campaign in the middle of the year which it supplemented with newspaper advertisements.[23] At the end of 1980, Rubik's Cube won a German Game of the Year special award[24] and won similar awards for best toy in the UK, France, and the US.[25] By 1981, Rubik's Cube had become a craze, and it is estimated that in the period from 1980 to 1983 around 200 million Rubik's Cubes were sold worldwide.[26] In March 1981, a speedcubing championship organised by the Guinness Book of World Records was held in Munich,[24] and a Rubik's Cube was depicted on the front cover of Scientific American that same month.[27] In June 1981, The Washington Post reported that Rubik's Cube is "a puzzle that's moving like fast food right now ... this year's Hoola Hoop or Bongo Board",[28] and by September 1981, New Scientist noted that the cube had "captivated the attention of children of ages from 7 to 70 all over the world this summer."[29]
