How to Solve a 7x7 Rubik's Cube | Part 1: Making Centers

What you need

7x7 cube, adult supervision required, notebook, pencil

Step 1

Sit at a clear table with your 7x7 cube and your notebook and get ready to focus.

Step 2

Find and memorize the center-most piece on each face so you know which colors belong opposite each other.

Step 3

Solve all seven centers one face at a time until each center area shows a solid color.

Step 4

Use slice moves to build one complete edge by bringing together its matching edge pieces until that edge is a single correct strip.

Step 5

Repeat the same edge-pairing method until all 12 edges are paired into complete edge strips.

Step 6

Align your solved centers and paired edges so the cube behaves like a 3x3 cube with the outer layers acting as faces.

Step 7

Practice the basic 3x3 right-hand algorithm by repeating R U R' U' slowly until you can do it without thinking.

Step 8

Solve the reduced cube like a 3x3 using the algorithms you practiced to finish the top and bottom layers.

Step 9

If the final layer looks impossible check every center and each paired edge carefully to find any mispaired pieces.

Step 10

If you still cannot fix the last layer ask an adult for help or look up a trusted parity fix for big cubes and apply it carefully.

Step 11

Share your solved 7x7 and what you learned by posting your finished creation on DIY.org

I can't find a 7x7 cube — what can I use instead?

Use a 5x5 cube or an online 7x7 simulator/app and follow the same sequence of memorizing centers, solving centers, pairing edges with slice moves, and reducing to a 3x3.

My final layer looks impossible — what should I check or fix?

If the final layer looks impossible, carefully re-check every center and each paired edge for mispaired pieces, unpair and rebuild any incorrect edge strips or realign centers before applying a trusted parity fix.

How can I adapt this activity for younger kids or more advanced learners?

For younger kids, simplify by practicing just finding and solving one or two centers or using a 3x3/5x5 while an adult handles parity fixes, and for advanced learners, time solves, learn full 3x3 algorithms, and practice parity corrections yourself.

How can we extend or personalize the 7x7 solving activity?

Personalize it by keeping a notebook log of center patterns and edge-pairing steps, decorating sticker centers for easier memorization, recording solve times, and sharing step-by-step photos or a video of your solved 7x7 on DIY.org.

Facts about Rubik's-style cube solving

⏱ Top speedcubers can solve a 7×7 in under two minutes with lots of practice and fast algorithms.

❌ Odd-layered cubes (like the 7×7) don’t have the special parity errors that even-layered cubes (like the 4×4) can show.

🔗 Edge pairing is a core step on a 7×7 — you group matching edge pieces before reducing the puzzle to 3×3 moves.

🧠 Solving big cubes like the 7×7 strengthens spatial reasoning and helps you remember multi-step algorithms.

🧩 V-Cube 7 (a mass-produced 7×7 cube) was released in 2008, making large-cube solving widely available.

How do I teach my child to solve a 7x7 cube?

Start by teaching cube notation and basic algorithms on a 3x3 or 4x4. Move to the 7x7: solve the center blocks first (make 7x7 centers row by row), then pair up corresponding edge pieces into single "slice" edges. Once reduced to a 3x3 state, apply familiar 3x3 solving methods. Learn parity fixes (edge/OLL parity) with a few special algorithms. Practice slowly, break steps into short sessions, and use video tutorials to reinforce each stage.

What materials do we need to solve a 7x7 cube?

You need a 7x7 Rubik’s-style cube (preferably a smooth-turning speedcube), a printed or digital guide to notation and algorithms, and a list of 7x7-specific parity algorithms. Optional items: lubricant for smoother turns, a timer or smartphone app to track progress, a notepad to record algorithms, and access to video tutorials. A comfortable, well-lit workspace and patience are also essential materials for successful practice.

What ages is learning a 7x7 cube suitable for?

Generally suitable for children aged about 9–10 and up who have patience and basic finger dexterity, though motivated younger kids can succeed with adult guidance. Prior experience solving a 3x3 and some exposure to 4x4 or 5x5 cubes helps. Break lessons into short sessions, supervise algorithm practice, and adapt pace to the child’s attention span. Always encourage fun over speed for younger learners.

What are the benefits of learning to solve a 7x7 cube?

Solving a 7x7 cube boosts spatial reasoning, pattern recognition, memory, and sequential thinking. It improves fine motor skills, concentration, problem-solving persistence, and the ability to follow multi-step instructions. Working through parity and complex algorithms also teaches patience and error recovery. It’s a great collaborative activity too—children can learn from parents or peers and gain confidence as they master challenging milestones.
