Solving a Rubik's Cube in 20 moves is one of the hottest topics for cubers. If you have mastered the skill of solving a Rubik's cube in 20 moves, it will be a showcase for you in front of your friends and family. This guide will provide facts and specific methods for how to solve a Rubik's cube in 20 moves.

Facts About Solving a Rubik's Cube

Theoretically, a 3x3 Rubik's cube can be solved within 20 steps from any position. This theory came out from mathematicians while they were trying to find out the minimum number of steps required to solve a Rubik's cube from all positions. It took several weeks for them to find out with a supercomputer, and the final conclusion is that every scrambled 3x3 Rubik's cube can be solved in 20 steps.

However, since humans are not a supercomputer, it is hard for human beings to solve randomly scrambled cubes in 20 steps. To achieve this goal, you need to have a deep understanding of cube algorithms and optimal solving techniques, a lot of experience and a bit of luck. Therefore, there is no cheat on how to solve a rubik's cube in 20 moves.

How to Solve the Hardest Scrambled Cube in 20 Steps?

The Superflip scramble is usually considered as the hardest scrambled 3x3 Rubik's Cube to solve, because it is the farthest possible pattern from the solved state. Therefore, let's look into the "cheat sheet", how to solve a rubik's cube in 20 moves. Before we start, here are several things to notice:

1. You need to place the cube exactly to the position the image presents and face it to yourself.
2. Clockwise and counterclockwise are related to each face, not the global position.
3. The abbreviation for movement will be explained below:

• U = Up layer
• D = Down layer
• L = Left layer
• R = Right layer
• F = Front layer
• B = Back layer

4. Each movement above must be 90 degrees clockwise by default, only if there is an apostrophe (') then the movement will be counterclockwise, and number means how many times you should move.
5. The image of the cube for each step is the pattern before your movement, so be aware of it.

Now, the so-called cheat sheet, how to solve a Rubik's Cube in 20 moves, is shown below: Step 1. Counterclockwise turn the front layer twice. Step 2. Counterclockwise turn the up layer twice. Step 3. Counterclockwise turn the back layer twice. Step 4. Counterclockwise turn the left layer. Step 5. Clockwise turn the right layer. Step 6. Counterclockwise turn the front layer. Step 7. Counterclockwise turn the right layer twice. Step 8. Clockwise turn the down layer. Step 9. Clockwise turn the up layer. Step 10. Counterclockwise turn the right layer. Step 11. Counterclockwise turn the back layer twice. Step 12. Counterclockwise turn the left layer. Step 13. Counterclockwise turn the up layer twice. Step 14. Counterclockwise turn the right layer. Step 15. Counterclockwise turn the back layer twice. Step 16. Counterclockwise turn the right layer. Step 17. Counterclockwise turn the back layer. Step 18. Counterclockwise turn the front layer. Step 19. Counterclockwise turn the right layer twice. Step 20. Counterclockwise turn the up layer.

How to Quickly Solve Any Scrambled Cube in 20 Steps?

If you want to start to learn about solving a Rubik's cube in 20 steps, you can use the AI-powered Rubik's Cube Solver by Delta technology. It is a simple, multi-platform application software that can bring out optimized solutions for scrambled Rubik's cube, and provides specific steps as reference. You can follow the instructions below to solve your cube.

Step 1. Open the app and tap the Start area.

Step 2. Fill the color with the camera or manually. If the color of your cube is rather tarnished, I recommend you fill it out manually.

Step 3. After all colors have been set, tap the Solve button.

Step 4. Tap the Start button to play the animation and follow it with your cube.

Note: Cube solver app will consider a 90 degrees movement as one move for the sake of education, so you might find the solutions take more than 20 steps.

Conclusion

With the information above, you will now have a clearer recognition of solving a cube. Solving a Rubik's Cube in 20 moves is technically possible, but practically very hard to achieve it. The guide above provides a hardcoded solution for the hardest scrambled cube, but there is no universal solution.

In order to get your cube solved faster, you can try Rubik's Cube Solver app. It records the cube pattern by camera and solves it in seconds. Also, it provides detailed instructions on how to solve a Rubik's Cube fast.

How to Solve a Rubik's Cube in 20 Moves FAQ

Q: What is God's algorithm 3x3x3?

God's algorithm 3x3x3 is the term for optimum solution to a Rubik's Cube, which means the algorithm that takes the fewest moves to solve the cube.

Q: How to solve a Rubik's cube at any position?

In order to solve a Rubik's cube at any position, it is wrong to solve one side first. Instead, you need to solve it layer by layer.

1. Solve the White Cross.
2. Solve the First Two Layers (F2L).
3. Orient the Last Layer (OLL).
4. Permute the Last Layer (PLL).
