Cast Coil Triangle Puzzle

The Finished Form: A Desk Statement

Set on a walnut desk or next to your monitor, this puzzle looks like something from an architect’s studio—a compact tetrahedron with intersecting bars, one side gleaming gold, the other showing off a rich copper patina. When the afternoon sun hits it, you’ll notice colleagues doing double-takes. “What is that thing?” is usually the first question. The second is, “Can I try it?”

At roughly 7-8cm (about 3 inches) per side and weighing around 0.6 pounds, it has enough heft to feel premium without being cumbersome. The dual-tone finish gives it a steampunk-meets-modern aesthetic that pairs well with mechanical keyboards, leather mouse pads, and the general vibe of someone who appreciates craft.

In Your Hands: The Solve Experience

Pick it up and you’ll feel the precision immediately—smooth die-cast edges, no burrs, each piece machined to slide against its neighbors with a satisfying resistance. The mechanism isn’t a twist-and-pull; it’s a coordinated slide where all six bars interlock at specific angles.

The first time you solve it, expect to spend 15-30 minutes rotating, testing, and having that “wait, that doesn’t…” moment before the pieces suddenly release. The “aha!” hits hard. Putting it back together is its own challenge—one that rewards spatial thinking over brute force.

Unlike wire disentanglement puzzles, this one stays assembled on your desk looking elegant until you decide to break it apart again.

Why This One?

Most metal triangle puzzles come in a single gold or silver finish. This dual-tone version stands out—the gold-and-copper combination adds visual depth and makes it look twice the price.
