Highlights:

 
World premiere! Our new toughie, Chunky-Octs...
Argentinian puzzler extraordinaire, Rodolfo Kurchan, proposed this 20-piece subset of Octominoes tiles as an independent brainteaser, and it was a brilliant move. These are all the octominoes that contain a 2x3 rectangle, with two squares attached in every different way. Oh, the wealth of challenges this set provides!   More....

 
World premiere! A famous grid, Tri-Chex...
We've turned a famous quilt pattern into a polyform set of 53 all-different tiles with a special color system. Hundreds of wonderful puzzle designs to build, in and out of the 11x12" tray. We've even engraved the grid lines into the tray for easier assembly. A wild experience with an elegant medium, with over a year of research into its logical secrets. A visual extra: can you see the overlapping ovals in its pattern?   More....

 
World premiere! Harrybourne Shape Puzzler...
Just 8 tiles, hundreds of figures to invent and solve. The building blocks are isosceles right triangles—squares sliced diagonally—in a unique new combination created by Jason Ancheta to entertain and challenge his kids. The ingeniously designed proportions of the tiles are different from all other puzzles of this kind. Treat yourself to the marvel of math plus art.   More....

 
World premiere! Five tricky tiles, Tetra-Tray...
Just 5 tiles, four each in four different colors, make hundreds of symmetrical quartets in a 6" tray. The brainchild of Tick Wang, this subset was selected from the 14 different "tetratan" tiles, each made of four isosceles right triangles, or squares halved diagonally. Fantastic variety of beautiful solutions—have a look!   More....

 
Gorgeous! Math jewelry, Moebius Pendant...
A Moebius strip is a unique geometric phenomenon that's 3D overall with a single two-dimensional surface. Our exclusive pendant designed by Joe Marasco is a 3D-printed track on which a closed loop of sparkling, colorful beads forms a movable Moebius structure. It demonstrates fascinating mathematics and is a joy to wear.   More....

 
A treasure... The Game of the Dragon...
A delightful new artistic embodiment of one of the world's oldest board games (the Royal Game of the Goose), and one of our most popular attractions at the Maryland Renaissance Festival, Katrina Weidig's adorable dragons lend their personalities to the race to the center of the board. Backed by the classic Viking game of Hnefatafl, the Game of the Dragon is our grandest entertainment. You'll love the custom-made miniature pewter dragon figurines as playing pieces.   More....

 
An instant hit! Our new game, LineDance...
It was love at first sight of how lively and beautiful this game turned out. Designed by our own resident mathematician, Elijah Allen, LineDance has 16 large hexagonal tiles, each hand-inlaid with three different colors of paths. The tiles played onto the white vinyl game grid form the "board". Up to six players can participate, each with three color-coded pawns, the "travelers". The strategy: your three travelers can only use matching paths.   More....

 
Here's the buzz! Our lively puzzle, Birds and Bees...
Created by our dear, long-time friend, math professor Andy Liu, this sweetheart of a puzzle with 28 tiles is made of combinations of hexagons, squares, and equilateral triangles. The birds and bees (and a couple of worms) appear in opposite, mirror image pairs, with 14 other symmetrical shapes. They nestle on a special, famous periodic grid. Build countless designs in and out of the triangular tray. The solution shown happens to have all the matched bird pairs on opposite sides as well. Three grid cards and a nice little workbook are included. It even plays two unusual games for two players. The three colors divide into groups of 9, 9, and 10 pieces.   More....

 
Endlessly varied designs! Tangled Triangles...
With 50 triangles, divided 12-16-20 among three colors (plus two as accent colors), create the most beautiful patterns. Every design will please, as each time you create a new work of art. Symmetries are especially attractive. Send us photos of your grandest creations.   More....

 
Imagine it and build it! Our art puzzle, Handy-Octs...
A mere five pieces, each a different octiamond (made of 8 equilateral triangles joined), are your tools for a most satisfying activity: "Imagine it and build it." Form them into countless artistic and recognizable shapes. Relaxing like meditation, rewarding with creative results.   More....

 
"Fences"...elegant partners for La Ora Stelo...
La Ora Stelo's inventor, Jacques Ferroul, has designed an exciting collection of special shapes with golden ratio properties that form borders around any combination of La Ora Stelo's tiles. These nine fence shapes, a total of 142 black pieces, come in three groups or kits, each kit for certain combinations such as convex and concave figures and even beautiful stars. Build a border, then fill it. Or form a shape and then construct a border around it. There is an amazing partnership between the golden ratio tiles of La Ora Stelo and the fence segments whose dimensions are carefully calculated for the golden ratio and proportions of La Ora Stelo. If you already own La Ora Stelo, add the fences next. You'll be glad you did.   More...

 
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 over a year of no shows for us to display our immensely playable gamepuzzles, we've been 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. We do hope to see you in the new year.

 
Gamepuzzles social media postings...
In addition to those occasional flyer mailings, we like to keep in touch also with folks in the math and puzzle world with condensed postings on Facebook and such platforms. If you've missed them, here's a running chronology. Links let you get the full story in our product showrooms, easy to order what you want.

 
Kadon Gamepuzzles® Universe... our fan site!
To our great surprise and delight, one of our puzzle-loving customers and fans, Andrzej Lewicki, created a Facebook page devoted entirely to discussions and solutions of our puzzles. His little icon, a famous sleuth, showed up now and then to add stories and smarts to the solving. Administered by a long-time fan and puzzle lover, Lee Luckeydoo Dreese, the site is open to the world, featuring any of our games and puzzles. This enthusiastic Facebook group brings out the best of art, math, and imagination, and sparkles with "the joy of thinking".

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 online...
After being closed for the 2020 season, 2021 and 2022 turned out with double vigor and enthusiasm. And the online presentations will continue year-round, too, for fans to visit all their favorite artisans virtually. The MDRF Marketplace is staying open around the clock, where you can interact Facebook-style with all of us and even make purchases. A special Lane Album was added to let you find individual artists by the location of their booth; see the big maps to find each booth. Here's a chronology of all postings of Ye Olde Gamery. And here is a nostalgic hour-and-a-half visit at the 2021 Festival filmed live-stream for Facebook by Michele Schultz. Four minutes, at around 38:00, are spent in Ye Olde Gamery. More...

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. You can preview the whole book at the publisher's website, and you can also order it from us as a lifetime treasure, in the best archival quality and now also in a more moderately priced hardcover edition. More...

Recent releases:

 
Pretty TilingsTMan 8-piece creative darling
This little set started as a limited edition goodie derived from a custom design made in 2021 for the University of Maryland's mathematics department for March 14, also known as pi day. It's such fun that we decided to keep it around for improvisational pleasure for ages 6 to adult. Makes a fine travel set, too.   More....

 
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. It soon begat a little offshoot, Handy-Tans, our newest pocket puzzle.   More....

 
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. Although each tile is differently proportioned, they have amazing ways of forming groupings and patterns. Like any family, the uniqueness of each individual makes for surprising and delightful adventures, from lacy lattices to tightly bonded beehives.   More....

 
Shardinaires-9TMOur newest dissection puzzle
Created by George Sicherman and expanded by Kate Jones, the 9 strangely shaped tiles can form all 12 pentominoes and all 5 tetrominoes, besides a wealth of convex, concave, symmetrical, and whimsical silhouette figures. Two games explore unusual strategies of border formation.   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. A slightly longer poetic video was shown at G4G in Atlanta in April 2022. Its collection of complex shapes and themes will keep you fascinated for years, and you can even extend its challenges by combining it with the StarHex-II set.   More....

 
Ternion FactorTMOur 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 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. 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....

 


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....

 



Silver Anniversaries!

We're celebrating these games on the 25th anniversary of our first publishing them. They have been continuously in print, 1997-2022. After the large number of new products in 1996, this year we added just five, including great big ones and small compact sets. Click on their pictures for full descriptions and to order. See their stories in our historical notes, Big and little.

  • Grand Roundominoes® — This set is the granddaddy of the Roundominoes theme. We hesitated a long time before releasing something so complicated and difficult. Still, enough customers were actually asking for something difficult, and so the Grand Roundominoes made its appearance. With so many pieces, and some small ones that roll easily, we decided to give the set a full lid to protect pieces from running off when the set sat as a work of art displayed on its easel. The lid also becomes a fine work surface when puzzlers are sorting out the pieces for solving. It's an amazing challenge, so beautiful when found.

  • Kite-MosaikTM — In 1994, we had introduced Penrose tilings based on the golden ratio, phi, named for Roger Penrose's research that opened a whole new door on mathematical and geometric variations and non-periodic tilings. Tiling with them takes hundreds of pieces. See the 1994 historical notes. To make them less intimidating, in 1996 Kate designed a small set in a decagon tray with just 45 pieces. The relative lengths of their sides are the endless decimal, 1.61803399..., known as the golden ratio. The cute little Kite Mosaik lets puzzlers explore all these esoteric concepts in playable and artistic form.

  • Nine Men's Morris/Fox & GeeseBy 1997 Kadon had a popular pavilion at the Maryland Renaissance Festival, and it occurred to us to research some games of historical interest and longevity. The first game Kate had ever learned as a child was "Nine Men's Morris", also called Mill, Muhle, Malom, Merelles, and many other variations in different countries, dating back to ancient Egypt. So we designed a beautiful wooden board, with a companion game, the medieval Fox & Geese, on the back, and with Celtic decorations by Chuck Coates to frame them. Fox & Geese includes two games and solitaires, too. It's a classic that captures the strategy of the ages for today's players.

  • Octiamond RingTM — The 66 "octiamonds" are all the distinct ways 8 equilateral triangles can be connected. Our original Iamond Ring (sizes 1 through 7 triangles) was published a decade earlier. We finally got the courage to release this much more difficult next level, size-compatible with the Iamond Ring for mega-constructions. An irresistible bonus was to fill the center with the 12 Iamond Hex pieces, dedicated to the most profound pursuers of big challenges, teen to adult. .

  • Snowflake SquareTM — This newest little version of the Snowflake series, a 4x4 selection, came about by popular demand for a smaller, easier form of the beautiful 6x6 Snowflake Super Square introduced a few years earlier. Their whole background story is told there. They are a very happy family, with versions for every level of skill.

Take a look!

 
A Periodic Table of Polyform Puzzles is now on YouTube!
On March 21, 2021, Kate gave an illustrated presentation on this topic online as part of the Gathering4Gardner Celebration of Mind. It was an amazing coincidence that the talk, which is in rhyme, was given on national poetry day. The video is about 24 minutes long, followed by a half-hour interview with the host, Tiago Hirth, digging into Kate's history of starting a puzzle business and developing it into a "playable art" form of math as art. A lovely musical background by Sergei Novikov accompanies the presentation. Easy to view on G4G's YouTube channel, no need to download a large file. Let us know how you like it!
