Void Cube: Swap two adjacent corners [duplicate]
I'm running into an issue on a new cube. None of the corners have been taken apart and switched. I've solved it a number of times already where I didn't run into this configuration. That said I keep ...

Solving a 90-degree rotated center on a 4x4 axis cube
I am trying to solve my 4x4 axis cube. I have solved the entire thing except for one last center, which is rotated 90 degrees clockwise. I have tried everything and I know it’s a parity case but I can’...

Is the exact number of states for the Rubik's cube on far distances (>=16 in QTM, HTM) known?
At https://www.cube20.org/ the numbers of states on distance 16 and beyond is written as: "about 1,100,000,000,000,000,000". Question: Are these numbers (for QTM and HTM metrics) are known ...

How do I reassemble a Rubik's Cube? [duplicate]
Disassembled my Magic Cube and I put it back together thinking it was the right way. Now every single time I try to solve it normally (I know how to solve Rubik's Cubes) there's always something wrong....

Plenty colors Rubik's Cube
On a Rubik's cube without any color, each square has 3 possibilities: I am not familiar with exact terms of the Rubik's Cube community so feel free to help me improve the vocabulary if necessary :) ...

Is an unmodified Rubik's cube solvable from looking at three sides?
Inspired by my own misinterpretation of this question, I thought I'd ask: Under what conditions does an initial view of three mutually adjacent sides give enough information to solve the cube blindly? ...

When only three sides are shown, can a Rubik's Cube be impossible?
Can a Rubik's Cube be reassembled so that when viewed from a particular angle (i.e. only 3 sides are visible) we know it cannot be solved? "Reassembled" here means taking a regular cube ...

Rubik's cube with restricted moves
Suppose you have some modified Rubik's Cube such that the face rotations are blocked unless a special edge (let's take the UR edge w.l.o.g.) unlocks the two faces where the edge is currently in. So ...

Edge round trip on 3x3x3 supercube
A 3x3x3 supercube is a Rubik's Cube with the centers marked in such a way that you can also see the orientations of the centers. Since there are 6 centers with 4 possible orientations each there are ...

Are there practical solvers (algorithms) to optimally solve the Rubik's cube for STM/other metrics?
The optimal (or "God's algorithm") is such an algorithm which produces the solution with the minimal number of steps possible. In theory one can do it by a brute force (BFS) like approach ...

How do you solve a ghost skewb such as Tony Fisher's Golden Cube?
A ghost skewb is a bizarre Rubik's cube variant, where the faces are all unique, odd shapes. The faces are all the same color, so the puzzle is solved when it's a cube again instead of a mess. ...
