Rubik’s Cube Solver
Colour in the 3D cube on screen so that it matches the cube in your hands, then press Solve. The cube starts plain, with every square white, so you only colour the squares that are another colour. You will get a short list of turns, and you can step through them one at a time and watch the cube change.
1. Hold your cube like this
Standard cubes have a white centre on top and a green centre facing you. Whatever colours your cube has, keep the same centre on top and the same centre facing you while you colour the cube. The middle square of each face cannot change.
My cube has different colours
Choose the colour of the centre square on each face of your cube. Every square you colour afterwards uses these six colours.
2. Colour the cube, then turn it
Look straight at a face by tapping its letter, or drag the cube to turn it around.
Turn a face. Clockwise, as you look straight at the face:
Anticlockwise (the apostrophe means anticlockwise):
Or type turns, for example R U R’ U’, and press Apply:
Everything done so far, oldest first. Undo takes back the last line.
Nothing yet. Each colour you paint and each turn you make is listed here in plain words.
3. Solve
Your turns
How to read the turns
Hold the cube the same way as in step 1. A letter is the face to turn: U is up, D is down, L is left, R is right, F is front and B is back. A letter on its own means a quarter turn clockwise as you look straight at that face. A letter followed by ’ means a quarter turn anticlockwise. A letter followed by 2 means a half turn.
How to use the Rubik’s Cube Solver
- Hold your cube with the white centre on top and the green centre facing you. If your cube has other colours, tell the solver the colour of each centre.
- Choose a colour and tap the squares on the 3D cube until it matches your cube. Every square that is already white needs no colouring.
- Press Solve. You get a short list of turns, and you can step through them one at a time or play them all.
- Do the same turns on your own cube, holding it in the same way.
Questions about the Rubik’s Cube Solver
How many moves does the solver use?
It uses a two phase method, which is the idea behind the best computer solvers. Solutions are short, usually somewhere in the low to mid twenties of turns, which is far fewer than a person using a beginner method.
What if my cube has different colours?
Open the My cube has different colours box and choose the colour of each centre. Every square you colour afterwards uses those six colours. A number on every square helps if two colours look alike.
Why does it say my cube cannot be solved?
The usual reason is a colouring mistake, such as ten squares of one colour. The solver counts the squares and checks that the pieces are possible. If a cube was taken apart and rebuilt wrongly, it may be a state that no turns can solve.
How do I read the turns?
A letter is the face to turn, and the apostrophe means anticlockwise. Read Rubik’s Cube notation explained, or practise in the Rubik’s Cube Trainer.
