About Pavel

Pavel Curtis is perhaps best known as the creator of the online world LambdaMOO, but he's been collecting mechanical puzzles for as long as he can remember, and has been designing new ones since 1999. Many of the designs on sale here have been featured over the years at the exclusive International Puzzle Party.

As a day job, Pavel works as a software architect at Microsoft.

Our Latest Arrivals

Edgewise

It's just a jigsaw puzzle, right? With only a couple dozen pieces, how hard could it be? Pavel's latest multi-stage solving experience will take you to the edge: can you guess the secret word he's thinking of? Can you get a word ... in Edgewise?

Tromino Trails

Conceived by world-renowned computer scientist and mathematician Donald Knuth, and brought to fruition by Pavel, this is an elegant set of five progressively more complex and difficult challenges, each using the same pieces and each with a unique solution.

Icicle Jam

Brrr! This big, frigid beauty recalls the shockingly blue ice of an Alaskan glacier, but assembling its complex interlocking pieces won't leave you cold. A striking attention getter in any room, begging to be taken apart. Do you dare to brave the elements and challenge this icy jumble?

Our Products

Get a Clue!

This investigator's magnifying glass has been broken! Repair the glass in two different ways to reveal clues to an old mystery. Can you put the pieces together to uncover the hidden meanings and solve this puzzling enigma, not just once, but twice?

Easy Eight / Hard Eight

The word “EIGHT” seems so innocent, so harmless, so devoid of either mystery or malice, doesn't it? Don't you believe it! Your job is to pack those five letters into each side of the tray, one supposedly “easy” and the other admittedly “hard.” Watch out, they're tricky!

Square Dance

Just four simple-seeming pieces to fit into each side of the tray, but they're much trickier than you'd think to get your head around, and there's only one solution per side! This award-winning puzzle design is available again for the first time in many years!

The Calibron 12-Block Puzzle

Originally copyrighted in 1932 by the son of Thomas Edison, this puzzle has been unavailable for over half a century. Can you assemble the 12 blocks into a single, solid rectangle? Just how easy a puzzle do you think an Edison would design?

Anansi's Maze

Anansi, the trickster spider god of African and Caribbean lore, has created a tricky maze with no walls, no paths to follow, not even any dead ends! Can you see through all of Anansi's tricks and find the secret he's left for you at the center of his maze? Pavel's series of multi-stage solving experiences continues in a very satisfying way!

Crystal Ball

Twelve stars with a deep or shallow notch on each arm. Can you match deep with shallow at every intersection to assemble this beautiful crystaline sphere? It's a tough challenge with a truly satisfying result.

Gamesters of Triskelion

A mysterious disassembled octahedron with an equally mysterious engraved tablet: what can it all mean? The third in our series of multi-stage puzzles!

Octamaze

Eight slim plastic triangles with tabs and slots on the edges, some strange etchings on the surfaces, and a whole lotta holes! A new multi-stage solving experience!

The Finnish Cross

Six flat pieces, each with two little tabs hanging off one edge, come together in just one way to make this handsome figure. An elegant and intriguing addition to any executive's desk.

Ooo Tray

A new concept in mechanical puzzles, the Ooo Tray is a multi-level solving experience with each level's solution leading you on to the next. The final answer is a single word; can you find it?

Easter Island Dominoes

Twelve pieces exhibit all the ways that two slightly "off" squares can be joined. In the first of four challenges, you "simply" fit them all into the tray. The final challenge has only three solutions; can you absorb enough Easter Island culture to complete it?

The "Perkinson Guest Bathroom Tile" Puzzle

Pavel found twelve ways to choose a group of three tiles from a lovely Arts and Crafts-style floor and then fitted them nicely into this tray. Can you find both possible packings?

Sleazier

There are just four pieces to fit into a tray that's clearly way oversized for them. How hard could that possibly be? It pays to keep this puzzle's name in mind...

The Devil's Half Doven

Each of the seven sticks has one dovetail tab attached along its length, and one dovetail notch cut across it. Your goal is to assemble the pieces with every tab fitted into a notch. Two of the four solutions will balance nicely on the end of one stick.

The Grand Vizier

Enter the strange world of non-periodic tiling! Can you fit these mind-boggling pieces into the turbaned head of the Grand Vizier? Once you do, there's a second challenge on the back!

Hinomaru: The Japanese Flag Puzzle

Can you recreate the simple symmetry of the Japanese flag from these twelve two-sided dominoes? Careful, the pieces aren't the same on their backs!
This version of the Japanese flag puzzle is made from stiff card stock instead of Lucite and comes without a tray. A portable brain twister at a bargain price.
