Tetso Puzzle Party Set – 17 Unique Metal Puzzles

17 Puzzles. 17 Different Challenges.

The Tetso Puzzle Party Set brings together 17 metal mechanical puzzles, each built around a different challenge.

Separate interlocked pieces, free trapped objects, manipulate deceptive bolts, and uncover hidden mechanisms. Difficulty and solving style vary throughout the collection, so solving one puzzle does not necessarily prepare you for the next.

Some challenges can be understood immediately. Others hide their logic behind an object that seems almost impossible to move.

That variety is what makes this set interesting.

Separate & Disentangle

Several puzzles in the collection challenge you to understand how two apparently locked objects can separate without bending or forcing them.

Two Nails

Your Challenge: Separate the two interlocked nails.

Two ordinary-looking metal nails become a surprisingly effective disentanglement puzzle. The pieces appear completely locked together until you discover the position that allows them to separate.

Two Keys

Your Challenge: Separate the two interlocked keys.

Two metal keys are connected in a way that looks far more permanent than it really is. Finding the correct orientation is the key to pulling them apart.

Taurus

Your Challenge: Separate the two interlocked Taurus rings.

A compact metal challenge built around two intertwined forms. Rotate, reposition, and study how the pieces interact until you find their escape path.

Q&Q

Your Challenge: Separate the two "Q" pieces.

Two matching Q-shaped pieces are locked together. The challenge is finding the movement that allows them to separate, then reconnecting them once you understand the mechanism.

Double M

Your Challenge: Separate the two interlocked "M" pieces.

The shapes seem to trap each other from every direction. Careful positioning reveals that there is a way through.

Hook

Your Challenge: Separate the interlocked hooks.

A classic disentanglement idea reduced to two deceptively simple metal forms. The solution depends on orientation rather than force.

Link

Your Challenge: Separate the linked pieces.

The pieces appear permanently linked, but their geometry creates a hidden route to separation.

Loop

Your Challenge: Separate the interlocked loops.

A compact metal brain teaser that asks you to discover how two seemingly trapped loops can move around and through one another.

Free the Trapped Object

These puzzles begin with something visibly trapped. The challenge is discovering how the surrounding structure allows it to escape.

Venus Trap

Your Challenge: Free the trapped spiked metal ball.

A cylindrical metal cage surrounds a spiked metal ball that appears far too large to escape. The solution depends on understanding the relationship between the spikes, openings, and available movement inside the cage.

Anchor

Your Challenge: Release the anchor.

The anchor appears securely caught within the surrounding structure. Manipulate the pieces carefully until you find the path that sets it free.

Caged Orb

Your Challenge: Free the captive sphere.

A metal sphere sits trapped inside its cage. The challenge is to understand the geometry well enough to release it without bending or forcing anything.

Free Star

Your Challenge: Free the trapped star.

A metal star is held inside an arrangement that seems to block every possible exit. Finding the right position changes everything.

Horseshoe

Your Challenge: Free the ring from the horseshoes.

A classic metal disentanglement puzzle built around two horseshoes and a trapped ring. The goal is to release the ring, then restore the puzzle to its original position.

Crack the Mechanism

Some puzzles in the set look more like hardware than brain teasers.

That is exactly the point.

Boltrix

Your Challenge: Thread the nut onto the bolt.

What appears to be a familiar nut-and-bolt problem quickly becomes something less ordinary. Examine how the pieces interact and discover the mechanism that makes the seemingly simple task possible.

Hexed Bolt I

Your Challenge: Remove the nut from the bolt.

The nut appears trapped on the bolt. Turning it normally won't necessarily get you where you need to go. The challenge is figuring out what makes this bolt different.

Hexed Bolt II

Your Challenge: Remove the nut and washer.

An evolution of the bolt puzzle with an additional trapped washer. Removing both requires understanding the hidden logic of the assembly rather than simply unscrewing the nut.

Discover the Sequence

Cannon Puzzle

Your Challenge: Fire the cannonball.

The Cannon Puzzle is a compact sequential discovery puzzle inspired by the historical Cannon and Ball puzzle.

A metal cannonball is trapped inside the barrel. Releasing it requires more than finding a single opening. You have to understand how the cannon's components interact and discover the correct sequence that allows the ball to escape.

It is a very different solving experience from the disentanglement puzzles around it and adds a sequential mechanical challenge to the set.

One Collection, Many Types of Mechanical Puzzles

The Puzzle Party Set is not a collection of 17 versions of the same mechanism.

Across the set, you will encounter:

• metal disentanglement puzzles
• trapped-object puzzles
• nut-and-bolt trick puzzles
• orientation challenges
• hidden mechanical relationships
• sequential discovery

Some puzzles ask you to separate two objects.

Others ask you to free something trapped inside.

Some look like familiar everyday hardware but behave in unexpected ways.

And one may make complete sense only after you've discovered a sequence of actions you didn't know existed.

That means the next puzzle can feel completely different from the one you just solved.

From Approachable to Seriously Difficult

Difficulty varies throughout the collection.

Some puzzles are good introductions to mechanical brain teasers and can be explored immediately by a new solver. Others require considerably more experimentation, observation, and patience.

Instead of buying a single puzzle at one difficulty level, the set gives you room to explore different mechanisms and discover which kinds of challenges you enjoy most.

Start with whichever one catches your attention.

Or choose the one that looks easiest and find out whether appearances are misleading.

Made to Be Solved, Reset, and Shared

Every puzzle in the collection can be restored to its starting position after it has been solved.

That makes the set especially good for sharing.

Solve one, reset it, and hand it to someone else without revealing the trick.

Put several puzzles on a table and let everyone choose their own challenge.

With 17 individual puzzles, the set works well for:

• puzzle nights
• family gatherings
• offices
• team activities
• desks and coffee tables
• mechanical puzzle collectors
• gifts for serious puzzle fans

Build a Metal Puzzle Collection in One Set

For someone new to mechanical puzzles, the Tetso Puzzle Party Set provides an introduction to several major styles of metal puzzle solving.

For an experienced solver, it offers a broad collection of Tetso challenges in one purchase.

And for a group, it creates something a single puzzle cannot:

multiple people getting stuck at the same time, for completely different reasons.

17 Ways to Get Stuck

One puzzle may take a few minutes.

Another may sit on your desk for days.

And figuring out one mechanism won't necessarily give you any advantage on the next.

That's the point.

The Tetso Puzzle Party Set gives you 17 different mechanical problems to solve, reset, share, and eventually hand to someone else without telling them the answer.
