It's Kadon's 35th Anniversary!
We've been celebrating all year, starting with the big Party of the Century at Kadon headquarters. And there will be more hoopla along the way right through and into the new year. The standard bearer, as in years past, is our incredibly versatile Poly-5 puzzle in a jade-colored tray and with Lucite pieces surrounding the number 35. If you already own Poly-5, just request a free grid for this challenge.

Getting ready for our annual Florida tour!
We've got a full schedule of art shows for the winter, from January through April 2015. Check our show calendar, and stop by to see us if you're in the area. These are all outdoor shows—wish us good weather!

Celebration of Mind and Gardner Centennial

The last weekend of the Maryland Renaissance Festival, October 18-19, 2014, at our pavilion, Ye Olde Gamery, was one of hundreds of official Celebration of Mind events held world-wide honoring the 100th anniversary of the birthday of Martin Gardner, the beloved author of dozens of books of mathematical games and a special inspiration to Kadon. Here's the background story. We also created a special souvenir puzzle for the occasion that you're welcome to print out for yourself.


4th Annual Doris Festival of Mind —results
High school students in eight East European countries participated in this tournament of intelligence and creativity organized by Zdravko Zivkovic, inventor of Doris. Judged by an international panel of art, math and puzzle connoisseurs, the Doris Championship spanned the school year. The awards ceremony was held in the Parliament of Vojvodina, Serbia. The top winner, Maja Gubic, received a deluxe Doris set from Kadon. More...


Trio-in-a-TrayTiny Tans' 25th Anniversary
For their 25th anniversary, we put our three 4-piece mini-puzzles into a single tray, with lots of new challenges plus all the classic symmetries. They're tucked in together in a shiny silver frame, each in its own color. The Tantalizing T, Square and Fair, and U Can Do It, all collaborate in creating delightful new fancies. More....


New! RunnuRound and wrap-around
What are the chances that in rows of randomly scrambled ten numbers, a run of three will turn up, in forward or backward order? Or even wrapping around from one end of the row to the other? Find 'em fast, outguess other players. Suspense builds as tiles flip. Unique bidding feature for bonus points. More....


New! Brace deluxe wood gameboard
After 15 years, our fascinating strategy game, Brace, originally produced as a jazzy wallhanging tapestry, now has a wonderful new look as a large wooden board, beautifully finished, laser-engraved and handpainted. Matching wood cylinders serve for 5 different games for two players plus a variety of interesting solitaires. Invented by Alan Kross-Vinson and developed by Kate Jones, Brace was a Games 100 selection in 1998. More....


New! Chasing Squares virtuoso tiling puzzle
Looks so simple and innocent and pretty, yet from the mind of our friend Jerry Farrell, an extraordinary puzzle inventory, Chasing Squares becomes a never-ending joy and surprise. The underlying geometry recalls tangrams, and our own Tiny Tans and Triangoes—8 isosceles right triangles and 8 "sheds" form positive and negative squares, promotes ingenuity. More....

New! L-Sixteen, where the holes mean a lot
This little brother to our Fill-Agree uses L-tetrominoes with every combination of 0 to 4 holes.You wouldn't believe what they can do with patterns of holes. Easy to extremely hard challenges make this a nice sequel to our very popular Vee-21. More....


Hopscotch — our 2014 "Games 100" honoree!

Games Magazine, for over 30 years the most prestigious publication on games and puzzles, both hands-on and electronic, used to publish an annual Buyer's Guide to Games, including the editors' choices of the 100 best new games of the year. Hopscotch in the Puzzles category brings to 52 our historical record of this honor. It may also be the last one, since Games has now changed its format and discontinued the Buyers' Guide as of December 2014. We're sad... though we'll keep the special Games Magazine selects section in our website in perpetuity. It deserves bragging about.


11 Unexpected Parallels — a six-minute talk
At the recent 11th Gathering for Gardner, Kate Jones gave an illustrated talk in verse, covering 11 surprising analogies or contrasting concepts. You can see all of it here.

Our Hexdominoes set is now 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 new 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.
