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.

Art exhibits... Baltimore area
A month-long mathematical art gallery exhibition will be held at Towson University in July 2015 and will then transfer to the Bridges Conference art exhibit at the University of Baltimore for July 29-August 1, 2015. Artists from around the world will have their art represented. Kadon's contribution to both events is its Grand Snowflake, consisting of 70 all-different square tiles with tessellated sides. While this large piece will be on display, a smaller working puzzle will accompany it for hands-on play by visitors. Various challenges involve matching colors, forming symmetries and wrap-around solutions, and completely enclosing one or two colors. This sweet little sample will be having its world premiere as a future Kadon family member. We've named it MiniMatch-I. Watch for formal announcements soon.
The 2014 GAPE award
Our Gamepuzzles Annual Pentomino Excellence prize for 2014 goes to "Double Entendre Pentominoes", an ingenious design by "Lord Minimal Impossible" of a pentomino rectangle solution that has a second and different solution painted on top. Scramble the pieces and try to reconstruct the painted pattern. His award goes one better by having a different solution painted on both sides, requiring 4 solutions in all, and presented in a nice wood case, complete with formal certificate. The solution shown here is only a sample, not the real one.
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.

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.
