How to fix an unsolvable Rubik’s Cube

If you’re looking at Rubik’s Cube solutions and your case does not correspond to any of those represented, then your cube in unsolvable.

Why there are Rubik’s Cubes that can’t be solved

Most of the times, the Rubik’s Cube becomes unsolvable because someone, intentionally or unintentionally, takes one or more pieces out of the cube. If the piece is now put back in the cube in a different position or orientation, the cube will now be impossible to solve.

How to fix the Rubik’s Cube

Unsolvable Rubik's CubeIn order to fix the cube, you need to take out the pieces that are not properly in place and put them back so that the cube is fully solved. Therefore, it is advisable to solve most of the cube, so you don’t have to remove and replace so many pieces.

To take out the pieces of the cube, turn 45 degrees one face (see photo). Put a thumb on each edge and make pressure in opposite directions.

Once you have taken out an edge, it’s easy to take out the rest of the pieces you need to change. Now, put the pieces back in the cube, but this time in the correct position. Finally, you have to insert the last edge with a face rotated 45 degrees (just like you did to take it out).

You can now scramble the Rubik’s cube and you will be able to solve it! (if you know how, hehe)

  1. Man what happened to me is that once I bought my cube I was able to solve it 30-40 times, and out of the blue I was not able to solve it anymore because 1 corner peace (yellow blue and green in my case) was not in the right place (everything else was). How is that even possible, to became unsolvable (nothing was taken out) after I solved it so many times? Do you know what was the problem?

    1. Hello, Igor. Sometimes the centerpieces have so little pression that the corners can rotate without moving from their own position.

      1. I have never taken apart the cube and it came assembled correctly, but still have one piece out of place. I didn’t pull it apart, but tried to and notice the colors are in the corresponding position. I noticed the comment above had a similar problem. Does it still need to be taken apart?

    1. No, you have to take the pieces apart. That’s why it is unsolvable.
      Another possibility would be to change the stickers, but afterwards they would not stick well to the cube.

  2. my cube is lent from my dad he says I can’t take it apart bcause it will get damaged, but it is unsolvable!!

  3. I have seen people solve my cube but i can’t I used a cube solver and it said that my cube was taken apart

  4. Perfect solution and perfect cube finally!!! Thank you so much!!! 2 pieces had fallen out when the cub got stuck, and I had to pull out the pieces due to having only 1 corner incorrectly oriented. Now that the cube is fixed, I will be able to solve it using all your steps without pulling out any piece in future. You rock, cool cat, cheers :)

  5. I’m using a Void Rubik’s Cube, which means it has no center pieces, and when I mix it up, and try to solve, two corners are swapped while everything else is solved. Then, I mix it up again and do solve again, and it somehow works. Can anybody explain this? I can’t move any pieces without taking it apart.

  6. Yesss!!! Solved the cube without pulling out any pieces this time. Thank you so much :)
    BTW, is there any trick to memorize the moves, I am not able to retain the algos :(

  7. i solved my cube by turning the corner pieces at last……it was solved then……is it correct to do it
