I have been trying to solve Rubik's cube using beginner's method provided here: https://ruwix.com/the-rubiks-cube/how-to-solve-the-rubiks-cube-beginners-method/

I ended up with just one last corner which is not oriented properly as shown in the picture. I cannot seem to solve it using R’ D’ R D algorithm, it messes up the whole square when the corner piece gets oriented. Every time I try to solve the cube, it again has just one last corner disoriented. None of the algorithms mention one last corner case. they always talk about 2 or more corners disoriented. I don't understand. Can someone explain whats happening and how to solve it?

one last corner not oriented properly

  • $\begingroup$ According to @ChrisCudmore's comment to the answer below, it's likely that this is a Speed Cube that accidentally went through a "corner flip" (not a legal Rubik's Cube move), and became unsolvable in that manner. To fix it, flip that corner back: "Essentially, you rotate a layer 45 degrees, and then you can spin one of the corner pieces overhanging the edge in place." $\endgroup$

You can't. Your cube is in an unsolvable state. You must take apart the cube and fix the corner. This happened because one piece was put in improperly. You can either flip one other piece or flip the disoriented piece

Someone pranked you

    $\begingroup$ Or else Shimano is pranking us and e.g. there's an oppositely-twisted corner opposite where it's not visible in the shot. $\endgroup$

    $\begingroup$ @JacobGoulden Oh...Thanks so much. I wasted few hours trying to solve it :(. Why would the online company sell a messed up cube (now i am not certain whether it was solved or not) $\endgroup$

    $\begingroup$ @Shimano Either it came solved and you accidently rotated a corner piece or it came unsolvable. Either way the cube in the above picture (assuming the other side we can not see is all solved) is unsolvable. If you rotate that corner then the cube will be solvable. $\endgroup$ May 17, 2016 at 13:20

    $\begingroup$ That's a speed cube (notice the notches in the corner to make it rotate when not completely aligned.) With these cubes, it's possible to do a "Corner Flip" maneuver. Essentially, you rotate a layer 45 degrees, and then you can spin one of the corner pieces overhanging the edge in place. It's possible you did this accidentally. $\endgroup$ May 17, 2016 at 15:19
