LunaTIC is an Expert-level 3D-printed Turning Interlocking Cube designed by Andrew Crowell. Goal: disassemble and reassemble 5 interlocking pieces into a perfect 4x4x4 cube. Difficulty: Expert. Solve time: 4+ hours. Best for experienced puzzle solvers who want the hardest TIC challenge in the series.

Best for: experienced mechanical puzzle solvers who have worked through Medium and Hard TIC puzzles and are ready for the series' most demanding challenge; also an exceptional gift for a puzzle collector who has seen everything.

The Challenge

LunaTIC looks like a neat little cube. It is not.

The disassembly itself is deceptive - pieces release in a sequence that feels almost accidental, which makes reassembly a genuine memory and spatial reasoning test. Unlike Hard-tier TICs where logical elimination eventually points to the answer, LunaTIC's 5 pieces can be oriented in combinations that seem correct right up until the final piece refuses to lock. Getting it apart is one thing - putting it back together is where the real chaos begins. Most solvers report multiple multi-hour sessions before achieving a clean reassembly.

FAQ

What is a Turning Interlocking Cube?

A Turning Interlocking Cube (TIC) is a 3D-printed mechanical puzzle where interlocking pieces must be rotated - not just slid - to come apart and go back together. The turning mechanic makes reassembly exponentially harder than standard interlocking puzzles.

How hard is LunaTIC compared to other TIC puzzles?

LunaTIC is rated Expert - the highest difficulty tier in the TIC series. It is significantly harder than Hard-tier puzzles like GeneTIC or MysTIC, with a 4+ hour solve time for most experienced solvers.

Is LunaTIC good for beginners?

No. LunaTIC is designed for solvers who have already completed multiple TIC puzzles at Medium or Hard difficulty. If you are new to TICs, start with a Medium-tier puzzle like TriTIC or TreTIC before attempting LunaTIC.

FAQ

Do You Ship Worldwide?

Yes. I ship anywhere. Orders typically arrive in 1-3 weeks depending on your location and how customs is behaving.

How Long Does Processing Take?

Some puzzles are produced on demand in our studio in Czech Republic. Processing usually takes 3-5 days before your order ships. During busier seasons it may take a bit longer.

Do Puzzles Come With Solutions?

Usually not. Sometimes you can find the solution on my YouTube channel. If not, feel free to reach out for hints!

What If I Get Stuck?

Good. That's the whole point.

But if "stuck" turns into "frustrated and not having fun anymore," email me. I'll send you a hint if you want a nudge. No judgment. Some puzzles took me days. A few took weeks. Some took months. Some took years. And some I have never solved - and that is part of the appeal.

Returns & Exchanges

Yes. You have 30 days. If the puzzle isn't right for you, send it back in the condition you got it and I'll refund you. If something arrived damaged or wrong, tell me and I'll fix it. Please be patient as we're a small team!

Are These Good Gifts?

People LOVE buying our puzzles as gifts. They're physical, they last forever, they don't need batteries, and they create a real moment - the person sits down, struggles, laughs, eventually solves it. That memory sticks.

If you're gifting, check the difficulty rating and pick something one notch below what you think the person can handle. Easier than you'd guess is usually the right call.

How Are the Puzzles Made?

All the puzzles are made with the help of my partner Puzzle Guy and his 3D printing studio in Czech Republic.

What Is a TIC Puzzle?

TIC stands for Turning Interlocking Cubes. They're a family of puzzles where wooden pieces interlock and rotate into a cube shape. The solve isn't just sliding pieces - you have to find the right rotations, in the right order. They're some of my favorite puzzles in the store.

Why Is Everything Turquoise?

I grew up near the sea in Israel. When life got loud or overwhelming, that's where I went to reset. Sit, watch the water, breathe. Things would settle.

The turquoise on this site isn't a branding choice I picked from a swatch. It's that color. The one I still see when I close my eyes and think of the place that calmed me down. I want you to feel a small version of that when you pick up a puzzle - a quiet moment, hands busy, head clear.
