Two-Piece TIC Collection

Every two-piece turning interlocking cube Andrew Crowell has made, in one set. Five cubes by Andrew Crowell, two pieces each, all of them asking the same deceptively simple thing: make a solid 5x5x5 cube. Medium difficulty, 30-60 minutes per solve.

Best for: Collectors completing their Crowell shelf in one go, solvers making their first attempt at a turning interlocking cube, and gift buyers who want a set that looks like an object rather than a toy.

Why Two Pieces Is the Place to Start

TIC stands for Turning Interlocking Cube. The pieces do not slide apart, they rotate apart, and that one difference is what stops people who are already good at interlocking puzzles - the move you need is the move you have been trained not to try.

That rotation needs somewhere to happen. Every TIC carries hollow space inside the finished cube - internal cavities the pieces turn through on their way out. You will never see them, because every outer face is solid. It is also why these five are 5x5x5 while Crowell's 4 and 5-piece TICs are 4x4x4: two pieces turning past each other need the extra room to do it in.

With two pieces there is nowhere for that rotation to hide. You are not managing five components and a build order, you are looking at one seam and working out which way it turns. That makes this set the natural on-ramp to Crowell's 4 and 5-piece TICs, where the same mechanic is buried under a lot more geometry.

Puzzles Included

  • EcstaTIC - the original two-piece TIC, and the gentlest introduction to the turning mechanic
  • EmphaTIC - the one that shows its hand. The teal piece reads as clean bands from the outside, so you can trace exactly where it sits and still fail to get it out. The natural second solve.
  • EclipTIC - the one that punishes a clean face. The top looks like a lid you could lift straight off. It is threaded into the body and will not move until it turns.
  • EnthusiasTIC - the one with no lead piece. Both halves grip in more than one direction at once, so nothing works loose gradually - it stays solid until suddenly it is not.
  • EclecTIC - the one with nothing to read. The seam wanders across every face instead of settling into a plane, so there is no flat side to study. Leave it until last.

FAQ

What is in the Two-Piece TIC Collection?

Five turning interlocking cubes by Andrew Crowell: EcstaTIC, EmphaTIC, EclipTIC, EnthusiasTIC and EclecTIC. Each is built from two pieces that rotate together into a solid 5x5x5 cube.

Are two-piece puzzles too easy?

No. Piece count is not what makes a TIC hard - the rotation is. All five are rated Medium and take 30-60 minutes, because the pieces have to turn past each other rather than pull apart, and that is not a move most solvers reach for.

Is this a good first set of TIC puzzles?

It is the best starting point in the store. Two pieces teaches the turning mechanic with the least noise around it, which is exactly what you need before moving to the 4 and 5-piece TICs.

Do they arrive solved?

Yes, all five ship assembled as finished cubes. Taking the first one apart is your first puzzle, and it is reliably easier than putting it back.

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.
