Does Rubik's Cube Increase IQ? The Honest Answer
Does Rubik's cube increase IQ? There's no good evidence that it does. Cubing trains specific skills, mostly memorizing move sequences (algorithms), recognizing patterns on the cube and turning 3D shapes in your head, and those skills mostly stay tied to cubing. It's a great hobby, not an IQ booster.
If you picked up a cube hoping to become a sharper reasoner, a faster route is to find out which reasoning skill is your weak link; IQ Tester does that in about two minutes. Find my weak spots
Short answer
A quick note first: many pages that answer this question are written by cube shops or brain-game sites, which have a reason to say yes. Here's a neutral take.
- Do Rubik's cubes make you smarter? Not in a general, IQ-test sense, as far as research shows.
- Is Rubik's cube good for your brain? It's an active, focused challenge, and it builds real skills.
- Does Rubik's cube require IQ? No. Most people solve it by learning a method, not by inventing one.
- Is solving a Rubik's cube a sign of intelligence? It's a sign you practised.
What solving a cube trains
When you learn to solve a cube, here's what you're actually practising.
Algorithm memory
The beginner method has you memorize a handful of short move sequences. Speedcubers learn many more. This is memory for motor sequences, like learning a dance or a piano piece.
Pattern recognition on the cube
You learn to glance at the cube and recognize a case: "That's the L-shape, so I use this algorithm." That's fast pattern matching, but for cube positions specifically.
Mental rotation
You track how pieces move when you turn a face, and you imagine the cube from other angles. That's spatial reasoning.
Finger speed and coordination
Speedcubing is partly a motor skill. Fast solvers train their fingers like musicians do.
Persistence
Your first solve is usually frustrating. Getting through that, and then chasing a faster time, is a real lesson in sticking with something.
| Cubing skill | Underlying ability | Does it carry over? |
|---|---|---|
| Learning algorithms | Sequence memory | Mostly to cubing |
| Recognizing cases | Pattern matching | Mostly to cube patterns |
| Tracking piece movement | Mental rotation | Possibly some, to similar spatial tasks |
| Finger tricks | Motor coordination | To cubing and similar hand skills |
| Chasing a PB | Persistence | Yes, as a habit |
Does it take a high IQ to solve a Rubik's cube?
People often ask about the IQ needed to solve a Rubik's cube. There isn't one.
The beginner method is a set of steps: make a cross, finish the first layer, finish the middle layer, then fix the last layer. Each step comes with a few algorithms. Kids as young as 7 or 8 commonly learn it. Can anyone solve a Rubik's cube? With a tutorial and a few hours of practice, most people can.
What's genuinely hard is inventing a solution from scratch without a guide. That's what Ernő Rubik did, and it took him about a month. That kind of problem solving is impressive. But following a known method is mostly memory and practice.
So is it a sign of intelligence?
Being able to solve a cube tells you someone learned a method and practised it. It doesn't tell you much else. Fast solvers are mainly people who've put in a lot of hours, the same way strong players in chess are.
What the evidence says
There's very little research specifically on Rubik's cubes and IQ, and nothing solid showing that cubing raises general IQ. Anyone quoting a specific IQ gain from cubing isn't pointing to good evidence.
What we do know comes from broader research:
- Brain-training transfer is limited. Big reviews of brain-training studies find people improve on what they practise, with little spillover to unrelated reasoning. That's the same story for sudoku.
- Spatial skills are trainable. A 2013 meta-analysis by David Uttal and colleagues in Psychological Bulletin looked at over 200 spatial-training studies and found spatial skills improve with practice, with some transfer to similar spatial tasks.
Put together: cubing probably helps a bit with spatial tasks close to cube-turning, and not much with general IQ.
Cubing and spatial reasoning
Spatial reasoning is the ability to picture shapes and how they move, rotate and fit together. It shows up on some reasoning tests as "which of these shapes is the rotated version" or "which net folds into this cube."
Does the Rubik's cube make you smarter at spatial puzzles?
Maybe a little, especially at mental rotation. To get more spatial benefit from cubing, try:
- Solve a step without looking at the back face. Predict where a piece is, then check.
- Describe a move before doing it: "R turns the right face clockwise, so this corner goes up."
- Try a different puzzle like a 2x2, a Pyraminx or a Megaminx. New shapes force fresh spatial thinking.
- Draw the cube from memory after a scramble.
The problem with self-testing
Here's where cubing on its own falls short as reasoning training. You might be great at spatial tasks already and weak in something cubing never touches, like mental arithmetic or putting reasoning into words. It's hard to know unless something measures you across all the skill types.
IQ Tester handles that measuring. You answer 16 questions, which takes about two minutes, and it pins down which of 7 problems is actually yours, such as pattern spotting, working memory or logic chains. Then you get a daily 10-minute drill that targets it. Find my weak spots
If you enjoy it, keep going
Does Rubik's cube increase IQ? Probably not. But there are still great reasons to cube:
- It's satisfying to solve something that looks impossible.
- Chasing a personal best teaches steady, measurable improvement.
- There's a big, friendly community, including competitions.
- It's a screen-free thing to do with your hands.
Cubing for beginners tip: learn the beginner method first, get consistent, then move to a faster method only once the beginner one feels automatic.
Train the reasoning the cube can't reach
Keep cubing for the fun and the personal bests. In the next two minutes, IQ Tester gives you a reasoning tier, names your weak spots, and starts you on a daily tip and 10-minute drill, with a streak and history to track progress like you'd track solve times.
FAQ
Does Rubik's cube improve IQ in kids?
There's no solid research showing it does. Kids who learn to cube build memory for move sequences, persistence and some spatial skill, which are nice benefits even without an IQ change.
What IQ do you need to solve a Rubik's cube?
There's no minimum. Most people learn the beginner method from a tutorial in a few hours or days. Solving it without any guide is much harder, but that's rare even among fast cubers.
Does cubing improve memory?
It improves memory for cube algorithms, which can be impressive among speedcubers. There's no good evidence it improves memory for unrelated things like school facts.
Is Rubik's cube good for your brain?
It's a focused, active challenge that builds spatial and memory skills specific to the cube. That's healthier than passive screen time, but don't expect broad IQ gains from it alone.
Do Rubik's cubes make you smarter at math?
Not directly. There's real group theory math behind the cube, but solving one with a method doesn't teach it. If you want math gains, practise math, such as mental arithmetic and estimation.
