2020 Maryland Renaissance Festival goes VIRTUAL!
After 42 years, it's strange to have the Revel Grove village silent and empty. The pandemic has closed it for this year, but with today's technology, the 16th century can be brought forward, and there are now online presentations for fans to visit all their favorite artisans virtually. The Artisan Marketplace is open around the clock, where you can interact Facebook-style with all of us and find where to make purchases. Sorry, no food or drink available. Technology is not quite up to Star Trek's transporter and replicator yet. A special Lane Album has been added to let you find individual artists by the location of their booth; see the big maps to find each booth. Stay tuned for more. Don't want to scroll for miles to find us? See a chronology of all postings of Ye Olde Gamery in one place. More...

Gamepuzzles Annual Pentomino Excellence Award 2019
We're proud to announce the winner of the 2019 GAPE award for the best new pentomino concept created that year: George Sicherman for his dissection puzzle of 9 strangely angled pieces that can form all 12 pentominoes and all 5 tetrominoes. Yes, 5 squares equal 4 squares! In fact, we loved it so much that we persuaded George to let us make it as one of our products for everyone else to enjoy, too. See Shardinaires-9 and the special design we made as George's award.

It is a celebration of toys, puzzles, and word-games, presenting to the world Greece's leading role in puzzles. Winning the "Archimedes" award was our beautiful and tricky, small but mighty StarHex-I set in the logical puzzle category.   More....

Recent releases:

Twenty-TansTMThe latest brilliant missing link
Created by Hans Weidig IV, this latest evolution of the tangrams concept is lightyears ahead of the traditional set. Its 20 tiles cover 16 squares and form hundreds of figures with mathematical purity. Four vivid colors add visual splendor. And there's something interesting for all ages, from introductory to the most sophisticated. It had its official world premiere during the 2019 Maryland Renaissance Festival. It soon begat a little offshoot, Handy-Tans, our newest pocket puzzle.   More....

Hex-PaveTMAn enchanting family of hexagon permutations
Created by Carl Hoff, these 15 tiles represent all the combinations of hexagons with sides of 1, 2, and 3 units in length, yet all their angles are equal. Although each tile is differently proportioned, they have amazing ways of forming groupings and patterns. Like any family, the uniqueness of each individual makes for surprising and delightful adventures, from lacy lattices to tightly bonded beehives.   More....

Shardinaires-9TMOur newest dissection puzzle
Created by George Sicherman and expanded by Kate Jones, the 9 strangely shaped tiles can form all 12 pentominoes and all 5 tetrominoes, besides a wealth of convex, concave, symmetrical, and whimsical silhouette figures. Two games explore unusual strategies of border formation.   More....

StarHex-ITMOur newest polyform puzzle
Created by Theo Geerinck of the Netherlands, this little brother to our beautiful StarHex-II has 14 tiles, with every combination of from 0 to 6 triangles attached on the edges of a hexagon. Developed by Kate Jones and Elijah Allen, the five colors code the pieces by type. For its world premiere, we submitted StarHex-I to the 2019 Annual Megistian Aenigma Agon puzzle competition on the Greek island of Kastellorizo, held in August 2019, and it placed first in the logical puzzle category, winning the Archimedes award. Its collection of complex shapes and themes will keep you fascinated for years, and you can even extend its challenges by combining it with the StarHex-II set.   More....

Ternion FactorTMOur newest strategy game!

If you're in Maryland, come see our booth at the Baltimore Christmas Village and have Art show and teach you this super game in person.   More....

The Four Horses of the Epic EllipseTMa wild ride!
The ellipses referred to are the four identical parts of our Surprising Pyramid. Our resident mathematician, Elijah Allen, was toying with them one day to see what two-dimensional figures they could make, besides building a four-level pyramid. In short order Elijah and Kate had accumulated over 50 designs, and new ideas kept popping. Kate remarked that the shape of that piece was called the horse. Elijah then had the brainstorm to turn the bulky balls into flat hexagons, making them a pentahex... one of the tiles in our Hexnut set. Good idea, so here are the four horses as our newest Pocket Puzzle. Great stocking stuffer and to take along anytime for doodling and creative fun. So few pieces, such a long name, and a really tiny price.   More....

Cookie JarTMdelicious conundrums
We present a combinatorial set by Michael Dowle... a tasty dish of 13 unique tiles, each with a different combination of 1 through 6 rounded triangles attached to the sides of a concavely curved hexagon. Their symmetry patterns are a visual delight and a solving challenge. Over 100 puzzle challenges plus two games. A neat platter of ever-intriguing food for thought, perfect for your coffee table.   More....

Silver Anniversaries!

We're celebrating these games on the 25th anniversary of our first publishing them. They have been continuously in print, 1995-2020. In 1994 we had introduced a dozen dramatic creations, including several based on the golden ratio and a few big beauties. We followed in 1995 with another two golden sets, some 16-piece sweethearts, and a trio of wooden wonders in ascending sizes. See their stories in our historical notes, Tilting towards tilings.

  • Deka-MosaikTM — Fifteen pairs of the two golden triangles surround 5 pentagons in a 7" decagon tray, in 4 color mixes. Amazing variations emerge. How many pentagons can they form?

  • Puzzling PentagonTM — two shapes of golden triangles, in two proportional sizes, 36 and 72 degrees, build a large pentagon with five-fold symmetries, or matched and non-matched groupings with their 4 colors. Great pedigree of great minds who proposed this set: Nob Yoshigahara, Donald Knuth, first presented at an International Puzzle Party. The 16 tiles travel in cloth drawstring bag, ready to entertain anywhere. Hardest challenge: separate all the colors, and separate the four smallest triangles as well.

  • Hexnut Jr.TM — The 16 tiles are polyhexes from size 1 through 4 complete, plus four pentahexes. Build hundreds of cool shapes, both in and out of the 7" tray. A game for two players is also included in the well-filled work book. We called it "junior" because it serves as a simple introduction to tiling with hexagons, where the larger Hexnut set includes all 22 of the pentahexes and is a much more complicated set of activities.

  • Rombix Jr.® — An octagon with 16 tiles formed from dissecting a large octagon into rhombuses. The four differently shaped tiles of the same color form a small (order-1) octagon. Based on "rhombic circle tiling" discovered by mathematician Alan Schoen and developed by Kate Jones into an artistic puzzle for all ages. Surprising images appear with every new combination.

  • Snowflake Super SquareTM — an exquisitely graceful set of 36 square tiles with every combination of hearts and spaces on their edges. Hundreds of designs to form in and outside the 9" tray. Seven years in development! And it has seven different strategy games for up to four players.

  • Throw a FitTM — 10 cubes with all different mixes of 3 colors on their faces play a probability game for any number of players, plus tricky puzzle challenges to solve with color arrangements, some reminiscent of Rubik's Cube. We introduced Throw a Fit in 1995, and ten years later switched from wood cubes to jumbo white plastic dice. It feels very good to roll them with two hands.

  • Kolossal PyramidTM — This majestic puzzle of 12 pieces built of wooden balls pegged and glued into the required shapes has had a checkered career. First introduced in plastic in 1986, then retired in 1989 and archived for a few years, in 1995 we decided to offer it by custom order only. Handcrafting it is a real bear. We may look into 3D printing, but at current costs that would be even more expensive and time-consuming. We're happy to keep it alive even in hibernation. Collectors can still acquire it. Just give our master craftsman enough time to build it. A thing of beauty, on a fine dimpled wooden base, and it has 47 solutions.

  • TransposeTM — lovingly handcrafted wood board by Christopher Clark, its inventor, and stylish wood checkers play 8 different games and a collection of solitaire puzzles. The title game is a tiny bit reminiscent of backgammon, with its own unique variations. It won first place on Games Magazine's list of the 100 best games of 1996.

New discoveries for OchominoesTM
This puzzle continues to be irresistible even though it's a really tough nut, inspiring new investigations of its amazing properties.
