Once-in-a-lifetime offerings... limited editions
Collectors' items, archive treasures, one-of-a-kind designs—while they last. We're selling out our special collections and archival sets of rare, vintage, and limited editions of puzzles and tilings. Once sold out, there will be no more. Many are already sold out. We have very few archival sets remaining, their quantities shown on the special order page.

 
Occasional flyers and special offers to keep in touch...
With no shows for us to display our immensely playable gamepuzzles, we're sending well-illustrated email flyers now and then, spotlighting special features and themes you may not have seen before. Here's a chronology of what we emailed starting in 2020, and we'll add new releases as they happen. If any catch your fancy, order safely and conveniently online and get FREE SHIPPING within the U.S. while we're without shows. We do hope to see you sometime in this new year.

 
Kadon Gamepuzzles® Universe... a new fan site!
To our great surprise and delight, one of our puzzle-loving customers and fans, Andrzej Lewicki, has created a Facebook page devoted entirely to discussions and solutions of our puzzles. His little icon, the sleuth Herlock Sholmes, adds stories and smarts to the solving. Open to the world and featuring any of our puzzles, this enthusiastic Facebook group brings out the best of art, math, and imagination, and sparkles with "the joy of thinking". It's free to join, and you can share pictures of your own solutions to add to the albums Andy is maintaining for each product. Visit, become a member, and share in the fun.

 
No art shows this year... see us virtually!
Our happy expectations for a fruitful year of art shows were dashed, casualties of the worldwide coronavirus calamity. All of our shows were cancelled. Avoiding crowds is the rule now. Check our calendar for where you can see us in online events and exhibits, or where we may have shows in 2021. In the meanwhile, browse through our website for new releases and old favorites. Give your brain and artistry a thrill. You can order them safely and conveniently online, and get free shipping within the U.S. More....

 
Our YouTube page is growing...
In 2016, Kate's son, Eric, launched a channel on YouTube with a video of how to solve that most vexatious puzzle, Instant Insanity. We've added two quaint poetic videos made in 2020, featuring a variety of our products, with more on their way, thanks to the professional skills of our associate, Hans Weidig IV. We've also added cool videos explaining how to play some of our games, written, filmed, and narrated by game designer Art Blumberg. Stay tuned and check our growing list of programs to view.

 
Maryland Renaissance Festival has gone VIRTUAL all year
After 42 years, it was strange to have the Revel Grove village silent and empty. The pandemic closed it for this year, but with today's technology, the 16th century can be brought forward, and there are now online presentations for fans to visit all their favorite artisans virtually. The MDRF Marketplace is staying open year round, around the clock, where you can interact Facebook-style with all of us and find where to make purchases. A special Lane Album has been added to let you find individual artists by the location of their booth; see the big maps to find each booth. Stay tuned for more. Don't want to scroll for miles to find us? See a chronology of all postings of Ye Olde Gamery in one place. More...

Golden Jubilee

Recent releases:

 
Twenty-TansTMThe latest brilliant missing link
Created by Hans Weidig IV, this latest evolution of the tangrams concept is lightyears ahead of the traditional set. Its 20 tiles cover 16 squares and form hundreds of figures with mathematical purity. Four vivid colors add visual splendor. And there's something interesting for all ages, from introductory to the most sophisticated. It had its official world premiere during the 2019 Maryland Renaissance Festival.

Hex-PaveTMAn enchanting family of hexagon permutations
Created by Carl Hoff, these 15 tiles represent all the combinations of hexagons with sides of 1, 2, and 3 units in length, yet all their angles are equal.

Like any family, the uniqueness of each individual makes for surprising and delightful adventures, from lacy lattices to tightly bonded beehives.   More....

StarHex-ITMOur newest polyform puzzle
Created by Theo Geerinck of the Netherlands, this little brother to our beautiful StarHex-II has 14 tiles, with every combination of from 0 to 6 triangles attached on the edges of a hexagon. Developed by Kate Jones and Elijah Allen, the five colors code the pieces by type. For its world premiere, we submitted StarHex-I to the 2019 Annual Megistian Aenigma Agon puzzle competition on the Greek island of Kastellorizo, held in August 2019, and it placed first in the logical puzzle category, winning the Archimedes award.

The Four Horses of the Epic EllipseTMa 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 JarTMdelicious conundrums
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.

A neat platter of ever-intriguing food for thought, perfect for your coffee table.   More....

Silver Anniversaries!

We're celebrating these games on the 25th anniversary of our first publishing them. They have been continuously in print, 1996-2021. By 1995 we had introduced a great variety of styles and themes of both games and puzzles. In 1996 we moved closer to the genre dearest to Kate's heart: Gorgeous geometrics. Click on their pictures for full descriptions and to order. See their stories in our historical notes, Gorgeous geometrics.

  • Brace/Nine Men's MorrisTM — was invented by Alan Kross-Vinson and fit our design ideals superbly, with its artistic grid, multiple games, non-violent themes, and potential even for puzzles. In its first form we styled it as a screen-printed canvas tapestry, with the classic Nine Men's Morris board on the back. Later we also crafted its deluxe wood version. In 1998, Brace won a place on Games Magazine's list of the 100 best games.

  • Diamond RainbowTM — created by Anneke Treep of The Netherlands, the 24 diamond-shaped tiles plus 6 single triangles have every combination of the 6 main rainbow colors and has been one of our most popular sets for 25 years. It makes endlessly many wonderful shapes and patterns, beloved by all ages.

  • Fill-AgreeTM — 25 tiles of sizes 2 through 4 squares (the smaller members of the polyominoes family), each with two holes in all different positions, plus six single squares, create many interesting patterns in 2D and 3D, easy and difficult. Transparent colors give a sense of stained glass, a puzzle plus decorative art.

  • Fractured FivesTM — Five squares imprinted on one side with partial pentomino shapes on each edge, and tangled ropes on the reverse. Match either side to join the squares into pentomino shapes with complete pentomino images or connected ropes on matched sides. One of our most venerable sets, created in 1986 on cardboard and made in limited quantities in 1996 for collectors, still as a paper set. A deluxe wood version came along in 2011; we'll celebrate that one in 2036. Yes, it can also be a game for two players.

  • Hexnut IITM — Daring to go big, this bigger brother showed up 9 years after our original Hexnut (1987). Its 82 different pieces, each consisting of 6 hexagons, including one with a hole in the middle, are sized to its kin and form a splendid hexagon in their own grand tray. After a quarter century of our making it, there are now many fearless solvers around the globe who have conquered it. Congratulations to them all.

  • Mini-Iamond RingTM — Nine pieces, the polyiamonds sizes 2, 3, 4, and 5, fit into their circle in 15,140 ways—yet only two of those solutions can separate all the colors! Form a huge number of other shapes outside the tray, from easy to exceedingly tricky. Try it, you'll love it.

  • Mensa logo puzzle — Mensa, the famous high-IQ society, has an interesting logo of a stylized M that represents a table, since mensa is Latin for table. Mensa also relates to thinking, so Mensans enjoy sitting around a table and conversing intelligently. Kate found that the logo was perfectly dissectable into 16 puzzle pieces we call polyiamonds, parts of our Iamond Ring set. There are over 14,000 solutions, all fairly difficult. Sorry, only Mensa members are eligible to purchase them. If you are a Mensan, email us.

  • PentaroseTM — One of our most gorgeous art puzzles with a great pedigree: based on research by Sir Roger Penrose (recipient of Nobel Prize 2020 for work on black holes) into non-periodic tilings. The 36 fractal-edged pentagons and parts of stars were prototiles in Penrose's investigation, and With our input they became parts of a decagon with intriguingly many solutions. Fascinating to play with, even after 25 years.

  • TransposeTM — invented by Christopher Clark, we styled this elegantly inlaid acrylic board with matching inlaid checkers as a contemporary companion to the original traditional wood set we introduced the year before. It plays 8 different games and a collection of solitaire puzzles. It won first place on Games Magazine's list of the 100 best games of 1996.
