Three Classic Puzzles. Three Different Challenges.

The 3 Brain Teaser Puzzle Gift Set brings together three well-known wooden mechanical puzzles, each based on a completely different type of problem.

You will pack seven irregular pieces into a cube, twist a connected chain of 27 wooden cubes back into shape, and take apart a six-piece interlocking Burr before figuring out how everything fits together again.

The set includes:

Soma Cube

Soma Cube Puzzle

Your Challenge: Build a 3 x 3 x 3 cube using all seven pieces.

Invented by Danish designer and mathematician Piet Hein in 1933, the Soma Cube is one of the classic 3D packing puzzles.

Its seven non-identical polycube pieces contain exactly 27 unit cubes, enough to fill a 3 x 3 x 3 cube.

There are 240 essentially distinct solutions to the cube, but finding even one without help can be surprisingly challenging.

Once you've solved the cube, the same seven pieces can also be used to create many other three-dimensional forms. Kubiya Games

Puzzle Type: 3D packing puzzle
Pieces: 7
Difficulty: 2/5

Snake Cube

Snake Cube Puzzle

Your Challenge: Twist the connected chain of 27 wooden cubes back into a 3 x 3 x 3 cube.

Unlike the Soma Cube, the Snake Cube has no loose pieces. All 27 cubes remain connected while you twist and rotate the chain into the finished shape.

The challenge comes from understanding how each section must turn while leaving enough room for the remaining cubes.

It is easy to get close.

Getting all 27 cubes into the correct final arrangement is another matter. Kubiya Games

Puzzle Type: Spatial assembly puzzle
Structure: 27 connected cubes
Difficulty: 3/5

Burr Puzzle

6-Piece Burr Puzzle

Your Challenge: Disassemble the six interlocking pieces and rebuild the original Burr.

The classic Burr is one of the most recognizable forms in mechanical puzzle design.

Six wooden pieces intersect to create a structure that appears completely locked together. The first challenge is understanding how the pieces release.

Then comes the harder part:

Putting them back together.

Once the Burr is completely disassembled, you no longer have the finished structure to guide you. Reassembly becomes a three-dimensional problem involving orientation, order, and the way all six pieces restrict one another. Kubiya Games

Puzzle Type: Burr / interlocking puzzle
Pieces: 6
Difficulty: 3/5

Three Different Ways to Think

What makes this set interesting is that solving one puzzle does not teach you exactly how to solve the next.

The Soma Cube asks you to think about volume, orientation, and empty space.

The Snake Cube asks you to visualize how a connected structure can fold through three dimensions.

The Burr Puzzle asks you to understand how individual pieces lock together and in what order they must move.

Together, they provide a compact introduction to three important areas of mechanical puzzle solving:

• Packing
• Spatial assembly
• Interlocking construction

A Good First Mechanical Puzzle Set

This set works especially well for someone beginning to explore mechanical puzzles because none of the three requires specialized knowledge before starting.

The objectives are immediately understandable.

The solutions are not.

That makes the set a good choice for:

• new puzzle solvers
• adults and teens
• mechanical puzzle fans
• students interested in geometry and spatial problems
• desk-puzzle enthusiasts
• birthdays and holidays
• anyone who enjoys taking things apart and figuring out how they work

Recommended for ages 12 and up.

Solve One. Then Try a Completely Different Problem.

Seven loose pieces.

Twenty-seven connected cubes.

Six interlocking bars.

Each puzzle begins with a simple objective, but each asks you to think about three-dimensional space in a completely different way.

That is what makes the 3 Brain Teaser Puzzle Gift Set a strong introduction to the larger world of mechanical puzzles.
