Old but still good news
Kadon's year-long 35th Anniversary continues
We've enjoyed celebrating our 35 years starting with the big Party of the Century at Kadon headquarters in May 2014, and we'll keep it up for a few more months.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, in a limited edition. If you already own Poly-5, just request a free grid for this challenge.
Our annual Florida tour is ending
We've got just one more show left of this year's Florida season. Check our show calendar for where we'll be next, and stop by to see us if you're in the area. These are all outdoor showswish us good weather!
Your dedicated and energetic Kadon crew managed to finish not just one but two Hexacubes in the last part of 2014. It is the largest project in our repertoire, with 166 all-different blocks of 6 cubes each. Such a beast eats up 10 Quintillions sets and 4 Super Quintillions. The 166 blocks plus 4 single cubes then nestle into a 10x10x10 cube. The lucky owners will have all the complexity they could ever want, even commingle them with the size-compatible Quintillions group and build even bigger structures.
It took five determined folks to process the parts to completion, including cleaning, staining, oiling, polishing, sanding, retouching, gluing, buffing, and then assembling into its fold-out treasure box with brass hinges and tiny padlocks. A prized task for which several people compete is that final assembly. This year we had the enthusiastic help of Elijah Allen, who took a series of progress photos of an awesome modular assembly which you can view in the Hexacube album on our Facebook page. Scroll back to December 23 in the Facebook timeline to see the final stages of the previous cube, painstakingly assembled one piece at a time, no prefab chunks. Here's one image; you can see Kate's strange socks on the side. 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.

If you've missed previous announcements or mailings, you can still track back to see what's been happening with us by browsing through our archives, especially the annual newsletters that sum up our year's doings. Here's the Archives index and the most recent (Christmas 2014) newsletter.
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. Through all those years Kadon won 52 "Games 100" selections plus 13 reviews, the last one in December 2013, in Games' last Buyers' Guide. The publishers have now changed format and have discontinued their extensive game reviews, featuring mostly paper and pencil puzzles. We're sad... though we'll keep the special Games Magazine selects section in our website in perpetuity. It deserves to be bragged about.

Check out unsolved tough challenges on the Contests page. Open to the world, with prizes to be won. Happy puzzling!
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 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.
