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 Arrival

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-level solving experience!

Our Products

Six Tabbed Planks

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.
