Why an Algorithm to Solve Rubik's Cube Is Actually Easier Than It Looks

Why an Algorithm to Solve Rubik's Cube Is Actually Easier Than It Looks

You’ve seen the kids at the mall. Their fingers blur, the plastic clicks like a frantic Geiger counter, and in twelve seconds, a chaotic mess of plastic becomes a perfect six-sided trophy. It’s intimidating. Honestly, it feels like they’re doing high-level calculus in their heads while chewing gum. But here’s the secret: they aren’t "solving" the cube in the way you think they are. They aren't looking at the colors and intuitively finding a path. They are executing a specific algorithm solve rubik's cube enthusiasts have refined over decades.

Most people see the Rubik’s Cube as a math problem. It’s not. It’s a muscle memory game.

If you can memorize a phone number, you can solve the cube. The logic behind it is actually quite mechanical. It’s about recognizing a pattern—say, a "T" shape on the top face—and then performing a sequence of moves that you’ve memorized to fix that specific pattern without messing up the parts you already finished. That’s all an algorithm is. It’s a "if this, then that" recipe for your hands.

The Mathematical Ghost in the Machine

Let's get one thing straight: there are 43,252,003,274,489,856,000 possible positions for a standard 3x3 cube. That’s 43 quintillion. If you had a different cube for every possible permutation, they’d cover the entire surface of the Earth in a layer several stories high.

Despite that terrifying number, any cube can be solved in 20 moves or fewer.

This is what researchers call "God’s Number." Back in 2010, a team including Morley Davidson and John Rokicki used Google’s infrastructure to finally prove this. They didn't just guess; they crunched the math. It took a massive amount of processing power to verify that no matter how badly you scramble it, the most efficient algorithm solve rubik's cube software could find would never need more than 20 twists.

But you aren't a supercomputer. You’re a human with thumbs. So you don't use the 20-move method. You use "Layer by Layer."

Why Your First Move Is Probably Wrong

Most beginners try to solve one side first. They get the white face done and feel like a genius. Then they realize that while the top is white, the side stickers don't match the center pieces of the other faces.

You’ve essentially built a house with a beautiful roof but no foundation.

The standard "beginner's" algorithm solve rubik's cube strategy starts with a cross. Usually white. But it has to be a correct cross, where the edges of the cross match the center colors of the side faces. Once you have that, you insert the corners. Now you have one full layer. You haven't just solved a side; you’ve solved a horizontal slice of the cube.

From here, it’s all about protecting what you’ve built.

The Meat of the Method: CFOP

If you want to get fast—like, under 30 seconds fast—you stop using the beginner method and move to CFOP. This stands for Cross, F2L (First Two Layers), OLL (Orient Last Layer), and PLL (Permute Last Layer).

  • F2L is where the magic happens. Instead of doing corners and then edges separately, you pair them up and slot them in together. It’s efficient. It's also where your brain starts to melt because there are 41 different cases to learn just for this step.
  • OLL is about getting the entire top face to be one color (usually yellow). You don't care if the side stickers match yet. You just want that top yellow sheet. There are 57 algorithms for this.
  • PLL is the final sprint. You have the yellow top, and you just need to swap the pieces around the rim to finish the cube. There are 21 algorithms here.

Total them up. That’s nearly 120 sequences to memorize. Professional speedcubers like Max Park or Feliks Zemdegs don't even think about these; their hands just "fire" the sequence the moment their eyes see the pattern. It's called "look-ahead." They are looking for the next pattern while their hands are still finishing the current one.

The Algorithm Solve Rubik's Cube: Thistlethwaite and Beyond

Beyond human speedcubing, there are even weirder ways to solve it. Morwen Thistlethwaite developed a famous algorithm in 1981 that uses group theory. Essentially, it restricts the types of moves you can make to gradually narrow down the "state" of the cube until it's solved.

It's beautiful and highly mathematical. It’s also completely useless for a human being trying to impress their friends at a party.

Most people just want a way to get the thing back to its original state. For that, you really only need about six or seven basic sequences. The most famous one is often called the "Sexy Move" in the cubing community (R U R' U'). It’s four simple turns. If you do it six times on a solved cube, the cube returns to exactly how it started.

Common Pitfalls and Why You Get Stuck

The biggest reason people fail when following an algorithm solve rubik's cube guide is "cube orientation."

If an algorithm tells you to turn the "Right" face (R), but you’ve tilted the cube slightly in your hand, you’re now turning the "Top" face (U) or the "Front" face (F). Everything breaks. The cube is a 3D coordinate system. You have to keep your "Front" face consistent throughout the entire sequence, or the math fails.

Also, tension matters. If your cube is a $5 dusty relic from a 1994 garage sale, it’s going to lock up. Modern "speedcubes" have magnets and rounded internal corners to allow for "corner-cutting"—where you can start the next turn before the previous one is even finished.

Actionable Steps to Master the Cube

If you're sitting there with a scrambled mess and want to actually fix it, don't just turn faces randomly. You will never, ever solve it by accident. The odds are literally against you by 43 quintillion to one.

  1. Learn the Notation. You can't read an algorithm if you don't know that 'R' means clockwise and 'R’' (R prime) means counter-clockwise. Spend ten minutes just learning what F, B, L, R, U, and D stand for.
  2. Start with the Daisy. Don't try to make the white cross immediately. Put four white edges around the yellow center. It looks like a daisy. From there, it’s much easier to line them up with their side centers and flip them down to the bottom to form the white cross.
  3. One Algorithm at a Time. Don't try to learn all of CFOP in a weekend. Learn the beginner's method. It only requires about four sequences.
  4. Use Your Left Hand. Most beginners are right-dominant. Force yourself to learn the "Left-handed" version of moves early on. It makes your solves much more symmetrical and faster.
  5. Stop Peeking at the Back. Trust the algorithm. If you’ve followed the steps for the front and top, the back pieces are moving exactly where they are supposed to. Looking around the cube just slows you down and confuses your orientation.

The Rubik's Cube isn't a puzzle for geniuses. It's a puzzle for people who are patient enough to learn a new language—a language written in quarter-turns and half-rotations. Once you stop trying to "figure it out" and start trusting the algorithm solve rubik's cube masters have already perfected, the cube stops being an enemy and starts being a fidget toy.

Grab a cube. Scramble it. Start with the cross. You’ve got this.
