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.

Our newest releases!

StarHex-II^TM Created by high-school student Jacob Lettie, this new polyform set of "polystars" was right up our alley. Its star grid is one of the 17 classic symmetry groups we love so much. Making only concave borders is a beautiful challenge, and separating the colors is a real doozie. New solutions win a prize! This one is by Kate. Thanks also to Elijah Allen for contributing many fine solutions and figures. StarHex-II looks pretty no matter how you assemble it. You'll love it.

Hopscotch^TM A new, original polyform set—the polyhops—has pieces composed of 1, 2, 3 and 4 squares joined that plot onto a hopscotch grid (alternate rows are displaced by half a square). Solve an open-ended collection of strangely difficult figures, small to large, simple to complex. In short, we're crazy about it. Invented by Thomas Atkinson, developed by Kate Jones.

Fractured Fives^TM This puzzle set is both making its debut to the world... and celebrating its 25th anniversary since Kate first designed it as a limited edition for puzzle collectors. This two-sided puzzle has multiple levels of difficulty as you match fractured pentominoes into complete images, or, on the flip side, connect a twisted web of rope segments. You'll be fit to be tied solving it.

Six Disks, with teddybears^TM Our unique number/TicTacTo/magic squares set now has a Teddybears theme, with each cheerful bear sporting a number on his chest. Playing with numbers is great brain practice for kids and, come to think of it, even for grown-ups. The set also includes our surprising and original "Vertical Tic-Tac-To" strategy game for 2 players. Bears' poses and colors may vary. Nicely bagged, the Six Disks Bears make a fine and enduring gift and take-along entertainment.

MemorIQ^TM (say "Memory Cue") The 24 inlaid hexagonal tiles in 4 colors match in intricate ways to form a gallery of interesting figures, a total joy. Created by Zdravko Zivkovic, styled by Kate Jones. One of the special features of MemorIQ is that its grid is one of the 17 classic symmetry groups: 3 squat pentagons form a hexagon, and hexagons fill the whole field. We're also very proud that MemorIQ was chosen for the Games 100 list and Buyer's Guide for 2012.

A+D+D+D^TM (say "Add") — Portable instant fun with numbers and strategy. The storage pouch is the gameboard. Add numbers on dice for sums that get your pawns on the board in rows of 3, 4 or 5. Invented by Devin Stewart; puzzles by Kate Jones.

These games are celebrating their 25th anniversary of first publication, and most have been continuously in print, 1988-2013. See more of their stories in our historical notes.

Just two copies of this special 25th anniversary limited edition for 2012 remain, while they last:

A highly condensed printable catalog has been updated and is available online as three .pdf files. It has 24 standard pages plus an order form, in full color, although it works just fine printed in gray. Feel free to download as much of it as you want, and you're welcome to print it out for Web-deprived friends, too. This catalog can also be viewed online with flippable pages.

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.

We own four additional, 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.
