o Holiday Greetings!
The homepage sports a group of cheery teddybears with our annual holiday messages and a couple of playful surprises. Our little Christmas trees also provide secret shortcuts...


Price increases...
Beginning in 2019, after holding our prices constant for 6 years, we are finally forced to adjust our prices across the board to reflect the ever-increasing costs of doing business in this inflationary world. We regret this necessity and therefore are keeping the old prices throughout this year's holiday shopping season. Order your gamepuzzles now, before the prices go up.

Historical celebrations...
The 9-weekend Maryland Renaissance Festival just concluded in Crownsville, MD, its 41st and our 35th season. Special annual event we hosted at our pavilion, Ye Olde Gamery, on the last weekend: Celebration of Mind, in honor of Martin Gardner's birthday anniversary. As a souvenir for customers, Kate had written a unique time travel tale that you can read online here: "When are you?" And here's a brief look at all our previous Celebrations of Mind.

Our Tricolor Stomachion is in a YouTube video!
Joe Marasco has created a fascinating video documentary about our Archimedes' Square puzzle, also known as the Stomachion. You can watch the amazing story of the origins and development of this 2200-year-old treasure and its many solutions as Joe explains its inner secrets. See the Tricolor Stomachion.

Christmas Village in Baltimore now going on...
Our little puzzle shop, Ye Olde Gamery, is on display in this charming old-world Christmas market, in the big heated tent down by Baltimore's Inner Harbor near the Aquarium and Science Center on Light Street. See us every day (except Dec. 3, 4, 10, 11) until Christmas Eve. See our show schedule for our full slate of winter events, including the upcoming Florida tour.

The long-awaited Hexnut rulebook has arrived!
"Under construction", it said for years, and our very patient fans bought this complex classic Hexnut set, knowing someday the book would also be ready. If you are one of these good souls, let us know your current address and we'll mail you the printed book. You can also access the digital file of it right here.

We have won The Archimedes Award for 2018
The 2nd Annual Megistian Aenigma Agon puzzle competition was held on the Greek island of Kastellorizo, September 1-3, 2018, organized by Pantazis Houlis. The Megistian Aenigma Agon is a Quadruple International Puzzle Competition (Interaction, Inscription, Illusion and Invention). The word Megistian comes from one of the island's names (Megisti), Aenigma means puzzle, and Agon stands for competition. It is a celebration of toys, puzzles, and word-games, presenting to the world Greece's leading role in puzzles. Winning the First Place "Archimedes" award was our splendid, seductive, though often difficult Ochominoes puzzle.   More....

2018 Doris Championships
The 8th Annual Festival of Mind and Doris Championships, organized by Zdravko Zivkovic, took place in many high schools in several European countries, building creativity and featuring our Doris puzzle. See the report of the winning designs, semi-finalists, and Grand Finale ceremonies. "Desert Island" (right) by Matej Fijacko won first place.

Simply beautiful... Flashes of Life
We offer, as a small departure from physical puzzles, a book of breathtaking photography by Robert L. Steinberger, Ph.D., each image paired with a haiku by Kate Jones. Flashes of Life, The Flower Collection comprises over 100 pages of digital photography, poetic interpretations, and stories. It's the first in a series of volumes on different subjects by this great visionary whose legacy will live on in the "flashes of life" he captured during a lifetime of passionate photography.

Recent releases:

Ternion FactorOur newest strategy game!
Art Blumberg's fifth beautiful and innovative strategy board game had its world premiere at the 2018 Maryland Renaissance Festival. Ternion means threes, and each turn is a triple-action adventure. Unlike any game you've ever seen, it lets you add, remove, move pieces as you choose your best combinations. If you're in Maryland, come see our booth at the Baltimore Christmas Village and have Art show and teach you this super game in person.   More....

The Four Horses of the Epic Ellipsea wild ride!
The ellipses referred to are the four identical parts of our Surprising Pyramid. Our resident mathematician, Elijah Allen, was toying with them one day to see what two-dimensional figures they could make, besides building a four-level pyramid. In short order Elijah and Kate had accumulated over 50 designs, and new ideas kept popping. Kate remarked that the shape of that piece was called the horse. Elijah then had the brainstorm to turn the bulky balls into flat hexagons, making them a pentahex... one of the tiles in our Hexnut set. Good idea, so here are the four horses as our newest Pocket Puzzle. Great stocking stuffer and to take along anytime for doodling and creative fun. So few pieces, such a long name, and a really tiny price.   More....

Cookie Jar
We present a combinatorial set by Michael Dowle... a tasty dish of 13 unique tiles, each with a different combination of 1 through 6 rounded triangles attached to the sides of a concavely curved hexagon. Their symmetry patterns are a visual delight and a solving challenge. Over 100 puzzle challenges plus two games. A neat platter of ever-intriguing food for thought, perfect for your coffee table.   More....

Deluxe wood Poly-5available again!
Our very popular Poly-5 set is back in a beautiful wooden version crafted by Elijah Allen. Lovingly stained and finished in rich hues, it has an elegant engraved wood tray. A limited edition had its world premiere in our Gamery pavilion at the Maryland Renaissance Festival in 2016. It's too beautiful to be limited.  More....


Tricolor Stomachion Monographthe latest word!
A six-month research project with Archimedes' Square (also known as "Stomachion") by Joe Marasco, Kate Jones, and Alex Streif has produced an amazing historical document, new findings after 2200 years of silence about the world's oldest documented puzzle.   More....


MiniMatch-Ifour colors dance merrily
This little set surprised us at every turn with the variety, intricacy and pretty patterns to which just 9 tiles can lend themselves and has become the newest member of our edgematching family.   More....


MiniTouch-Ifour shapes link up gracefully
This version, designed by Elijah Allen, is a tactile equivalent of MiniMatch-I, where four kinds of contour carved out of the sides of squares form circles, diamonds, hexagons and curvy octagons in the negative spaces. Great for touch-solving by vision-impaired players, too.  More....


Ochominoes24 unique octagon dominoes
A brand new way to tile with octagons and squares, form hundreds of delightful patterns. This set epitomizes "the joy of thinking", making breathtakingly beautiful designs. It was created as a unique new polyform set, "polyocts", by Dan Klarskov of Denmark. Each piece looks like a little cartoon character. What would you name them? Can you find the cat, the mouse, the teddy bear? The turtle, owl and penguin? Would you believe there are 119 ways to make symmetrical pairs?  More....

Special edition... Octiamond Stack
We're offering a special and very limited edition of the 66 octiamonds, styled as 6 separate "petals" that stack, each in a little tray. Only while they last. And only for the hardiest puzzle lovers and collectors—this one's a doozy, even with millions of possibilities.  More...


Silver Anniversaries!

We're celebrating these games on the 25th anniversary of our first publishing them. They have been continuously in print, 1993-2018. In 1992 we had introduced just two new sets. We made up for that in 1993 with a deluge of 9 lavish creations. See more of their stories in our historical notes, Opulence in acrylic and wood.

The Rusticana Collection
These custom-made "mixed-media" ensembles interpret several Kadon games also offered in all-acrylic versions. They are crafted with passionate precision in lasercut wood, dark and blond, intertwined with luminously tinted transparent acrylics that give a stained-glass effect, in handcrafted reversible wood display cases. These are among our loveliest art puzzles, with thousands of solutions for each.

  • Deluxe Rombix® — 16 tiles formed of 4 sizes of rhombs as singles and concave pairs. The elegant mathematics of "rhombic circle tilings".
  • Deluxe TrifoliaTM — 24 graceful triangles, all different, nestle in a checkerboarded hexagon of wood and acrylic.
  • Deluxe SextillionsTM — 36 hexominoes with 12 special pieces contrasted, a pretty parity paradox.
  • Deluxe Super Roundominoes® — Ten curvaceous shapes of 1 through 4 "rounds" and "bridges" intricately interweave with 3 tones of wood and 3 Lucite hues.
  • Deluxe Snowflake Super SquareTM — 24 distinct plus 12 duplicate tiles interlock with alternating bands of wood and transparent hues. Exquisite!
