Fastest Rubik Cube Solver Calculator
Rubik's Cube Solver works out Solution and Solution length (half-turn metric) from Scramble sequence and Sticker colours (54 facelets). The default figures on this page give solution of R U2 R' U' R U' R'; change any entry and the result, the working and the sources update together.

9 steps
- Apply the 7-move scramble to a solved cube.
- Read the state: 4 of 8 corners and 9 of 12 edges are in their home slot; 3 corners are twisted and 0 edges are flipped.
- Check the three laws of the cube: total corner twist is 0 mod 3, total edge flip is 0 mod 2, and the corner and edge permutations have the same parity. All three hold, so the state is reachable by legal turns.
- Phase 1 (to G1: orient edges): already there
- Phase 2 (to G2: orient corners, place the E-slice): R U2 R' U' R U' R
- Phase 3 (to G3: place every cubie in its orbit): already there
- Phase 4 (to solved: double turns only): R2
- Cancel turns of the same face where they meet, giving 7 moves (8 quarter turns): R U2 R' U' R U' R'
- Replay the solution on the entered state: the cube comes out solved.

What the Rubik's Cube Solver calculates
Analyses a Rubik's cube state from a scramble or sticker colours, checks it against the three cube laws, and solves any legal position with a four-stage Thistlethwaite descent, verifying the solution by replaying it before answering.
How to use this Rubik's Cube Solver
Enter Scramble sequence and Sticker colours (54 facelets). Solution updates as you type, and “Use a worked example” loads checked figures you can adjust. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Solution, Solution length (half-turn metric) and Solution length (quarter-turn metric).
The method follows Morwen B. Thistlethwaite, 45-52 move strategy for the Rubik's Cube (subgroup chain G0 > G1 > G2 > G3 > G4), Herbert Kociemba, Cube Explorer documentation: cubie-level cube model, facelet layout and move tables, David Singmaster, Notes on Rubik's Magic Cube and Michael Reid, superflip in 20 face turns, Cube Lovers mailing list, January 1995.
Superflip: every edge flipped in place, the most distant position from solved example
With mode: scramble, Scramble sequence: U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2, the calculator returns State is legal: yes, Solution replayed and checked: yes. This example is checked against an independent source in the test suite.
What you can compare
Change one input at a time to see how it affects Solution, Solution length (half-turn metric) and Solution length (quarter-turn metric). The inputs you can vary are Scramble sequence and Sticker colours (54 facelets).

Frequently asked questions
What are the 7 steps to solve a Rubik's cube?
On the figures this page opens with, the solution is R U2 R' U' R U' R'. No single number fits everyone: it follows Scramble sequence and Sticker colours (54 facelets), so enter your own above and the answer updates as you type.
How can I solve Rubik's cube easily?
Analyses a Rubik's cube state from a scramble or sticker colours, checks it against the three cube laws, and solves any legal position with a four-stage Thistlethwaite descent. Open “How this is worked out” beside the result to see each step for your own figures.
What is the easiest trick to solve a Rubik's cube?
It needs Scramble sequence and Sticker colours (54 facelets). Nothing else is required, and the figures stay in your browser.
What are the steps to solve a Rubik's cube?
The result gives Solution, Solution length (half-turn metric), Solution length (quarter-turn metric), Solution replayed and checked, State is legal and Already solved, each labelled with its unit so the figure can be read on its own.
What information do I need for the Rubik's Cube Solver?
You need Scramble sequence and Sticker colours (54 facelets). The page opens with default figures that give solution of R U2 R' U' R U' R', so you can see the scale before entering your own.
What does this Rubik's Cube Solver show?
It shows Solution, Solution length (half-turn metric), Solution length (quarter-turn metric), Solution replayed and checked, State is legal, Already solved, Cube state (54 facelets, URFDLB) and Inverse of the scramble, with the working and any warnings for your entries.
