Here's our year-end 2017 gamepuzzles newsletter
In case you haven't seen it, here's a brief summary of all our doings in 2017, with website updates and a few surprises. More....

A special welcome to Sue Bare
Sue is the daughter of Kate Jones and has come on board with Kadon to help with all aspects of managing the business, from sales to production, marketing to logistics and quality control. Her talents, enthusiasm, energy, professional skills and broad experience in business are assets that will raise our humble enterprise to new levels. Sue has two grown children and has moved from Minnesota to Maryland to take on these new challenges. We welcome her with open arms. You'll meet this wonderful lady at most of our upcoming shows in the Florida winter season.

Our Florida tour is in full swing...
Kate and Sue are at the winter art show circuit in Florida. The weather is slightly cooler than usual, though sunny and mild compared to the northern states. Lots of visitors to the shows come from places like Michigan and Indiana, finding refuge in the Sunshine State. See our show schedule for our whole slate of events. And if you're in the area, come see us.

We won The Apollo Award for 2017
A puzzle competition, the 1st Annual Megistian Aenigma Agon, was held on the Greek island of Kastellorizo, September 1-3, 2017, organized by Pantazis Houlis. The Megistian Aenigma Agon is a Triple 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 and word-games, presenting to the world Greece's leading role in puzzles. Our winning entry in the aesthetics category was our charming little MiniMatch-I.   More....

New Guest Showcases
Our friends at ThinkFun have produced, among all their excellent educational products, a few that fit perfectly into our combinatorial themes, and we are happy to offer these through our website: Square by Square, Pathwords, Color Cube Sudoku, and Swish Jr. These are in addition to ThinkFun's classics that we have carried for many years now: Shape by Shape, Block by Block, IZZI and IZZI2. Some of these are out of print, so only available from us while our supply lasts. (Kadon's own products never go out of print!)   All these product names are proprietary trademarks of ThinkFun, Inc.

2017 Doris Championships
The 7th Annual Festival of Mind and Doris Championships, organized by Zdravko Zivkovic, took place in many high schools in 7 countries, building creativity and featuring our Doris puzzle. See the Grand Finale ceremonies and winning designs. "The Eye" (right) by Ambra Rossi won first place.


The 2017 GAPE award
Our Gamepuzzles Annual Pentomino Excellence award for 2017 went to "73 Symmetries", a great research project by Livio Zucca and a team of five international puzzle wizards to find all the non-hole 4-way symmetrical solutions with the 12 pentominoes. 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...

World's best music... The Caranza Collection
Caranza is the stage name of Patric Hale, a phenomenal Meistersinger who has achieved both tenor and baritone mastery of 12 genres of music in 7 languages, with moving emotional sensitivity and blow-you-away power of delivery. He has a repertoire of hundreds of recorded songs, available on 22 CDs, ranging from Elvis, Sinatra, Tom Jones and Billy Joel to Broadway tunes, German songs, Italian and German opera, and more.

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.

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? 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!

We own four very cool domain aliases. Each is just a title page ("splash page") and links to the respective major sections of the official gamepuzzles website. Take a look; they're jazzy.

Our Hexdominoes set is also a registered trademark and has its own independent website and domain name, with additional materials not found in our main website, such as the entire rule book and actual-size grids to print out for use with special figures. We plan to offer new challenges there eventually and maybe even some play-online features. A little logo for it is on the bottom of the homepage. And check out the awesome new designs we've found for this amazing set.
