Goh Pit Khiam is a Singaporean puzzle designer with one of the most diverse catalogs in the modern mechanical puzzle world. He's designed over 60 puzzles spanning packing, sliding, and complex sequential mechanisms, and has earned recognition at the IPP Nob Yoshigahara Puzzle Design Competition multiple times across his career.
Why I love Goh's work
Goh designs puzzles where the sequence is the star. In most of his work, finding the right sequence of moves is the entire challenge - and once you find it, executing the solve is a real delight. There's a specific kind of satisfaction in a Goh puzzle that other designers don't quite produce. The "secret" of the puzzle isn't a trick or a hidden mechanism - it's the order of operations, the rhythm of how the pieces interact.
That's why his puzzles are so rewarding once you find the answer. The solve feels like a small piece of choreography, not a brute-force assembly.
What the puzzle community says
Goh has earned multiple Jury Honorable Mentions at the IPP design competition - including for Road Blocks and Number Blocks at IPP35, and for Chain Store at IPP36. In 2026 his puzzle "Elbow Room" was selected for the Puzzlers' Award. Cubicdissection and other premium makers have produced wooden editions of his designs for collectors, including the highly sought-after Ternary Burr made with Eric Fuller. Puzzle Ramblings has reviewed many of his designs and consistently highlights the original mechanical thinking in each one.
Where to start in his catalog
I currently carry Chain Store, the puzzle that earned Goh his IPP36 Jury Honorable Mention. The challenge is to pack a chain of pieces into a box through a restricted opening, and the solve is a perfect example of why Goh's sequences are so satisfying. There's exactly one rhythm that works, and finding it feels like solving a small choreographed dance.
I'm working on bringing more Goh puzzles to the store. He has a deep catalog full of designs I'd love to share.

He has been a regular presence at the IPP Nob Yoshigahara Puzzle Design Competition, earning multiple Honorable Mentions across the years.
What makes a Goh puzzle different?
The sequence is the star. Goh's puzzles aren't about discovering a hidden trick - they're about discovering the right order of moves. Once you find that order, the solve becomes a choreographed sequence that's genuinely fun to execute, and that "aha" moment is what makes his work so rewarding.
Which Goh puzzle should I buy first?
Chain Store. It's his IPP36 Jury Honorable Mention winner and a perfect introduction to his sequence-driven design philosophy.
Do you sell the wooden versions?
No, we produce them in 3D printing, since we aim to make great designs as available as possible. Wooden editions of Goh's puzzles are produced in small runs by makers like Cubicdissection and Eric Fuller for collectors. The plastic version you see here is made with care to preserve the elegant solve Goh designed.
Will more Goh puzzles be added?
I can't promise it, but I'm working on it. Goh has a deep, diverse catalog and there are several designs I'd love to share with my customers.
If you enjoy Goh's work, also explore puzzles by Osanori Yamamoto, Frederic Boucher, and Yasuhiro Hashimoto - some of the other modern designers whose puzzles I'm honored to carry.
