# the Infinity Puzzle™: a new kind of jigsaw puzzle

#### Have you ever done a puzzle that has no beginning or end? Where you don’t know up from down? Get lost in the infinite galaxy puzzle.

The infinity puzzles™ are a new type of jigsaw puzzle inspired by topological spaces that continuously tile. Because of that, they have no fixed shape, no starting point, and no edges. They can be assembled in thousands of different ways.

Our puzzles are all about bringing back the artistry and playfulness of traditional hand cut puzzles while exploring the possibilities of new technology. A part of that artisan tradition are “trick” puzzles, puzzles that can be assembled in multiple ways often to create a witty pun or interesting transformation. Our infinity puzzles™ build on that tradition with a new mathematical twist that would be almost impossible with hand cutting, a puzzle that tiles in every direction. Our generative puzzles are made with math, science and lasers. The intricate branching shapes of our puzzle pieces emerge from a simulation of crystal growth and are lasercut from plywood. By combining mathematical simulation with precision CNC cutting, we create new kinds of jigsaw puzzles that could never be made before.

## the Infinity Puzzle™

### a small yet challenging puzzle based on a torus

The Infinity Puzzle™ ($50, 6 x 6 inches, 51 pieces) is a challenging wood puzzle that tiles in the plane. This means that any piece on the bottom can be moved to the top and a piece on the right can be moved to the left. Multiple copies of the puzzle can be combined in different colors to create abstract patterns and shapes. Topologically, we can say this is equivalent to a torus, which can be described by its fundamental polygon showing how edges of a square map to each other to make a closed shape. We create the tiling piece shapes by modifying our simulation to wrap like a torus. It was first created for the 2016 Puzzle Parley. This puzzle is extra challenging as it has no image or defined shape to guide assembly. Multiple infinity puzzles™ can be combined to create a larger continuous puzzle. The image above shows some of the creative combinations possible with two infinity puzzles™ of different colors ($75, for two).

### a puzzle that tiles infinitely across both sides, based on the Klein Bottle

Wood puzzles are considerably more expensive than cardboard ones but they allow for more interesting piece shapes and last for generations. Since this puzzle is double sided (and the two sides are continuous!) it is trickier to make than our other wood puzzles.

i would buy at least four of these and make a massive puzzle

5. #### Rick

The selling point of this “puzzle” is that it has infinite solutions.
I think that makes this a toy, rather than a puzzle.
Still, cool.

1. #### Jessica

It does not have infinite solutions. But there are thousands of shapes you can make as you tile around the Klein Bottle surface. I think the selling point is that the image wraps from one side to another which makes it extra difficult.

6. #### Howard

Can you combine multiple infinite galaxy puzzles together?

1. #### Jessica

hypothetically yes, but we haven’t tried it. I’m not sure the image alignment between two copies of the puzzle would be “perfect” enough to look seamless.

7. #### Lori

This could help my child with Sensory Processesing Disorder. I would order one in a heartbeat.

8. #### Carolyn McFarland

Where does one purchase the puzzle?

1. #### Jessica

You can purchase the puzzle on our website here: http://n-e-r-v-o-u-s.com/shop/line.php?code=12

I would love the infinite puzzle for a Christmas gift. Is there any chance for that?

1. #### Jessica

Hi Stephanie. We are sold out of puzzles for Christmas delivery.

10. #### dick fischbeck

Is this a Penrose tiling?

no

11. #### Austin richards

I wish it was affordable for me , would love to cover an entire 8’x 8 section of my wall in my living room with only this Galaxy looking one , absolutely love it though as well as challenging puzzles , definitely on my wishlist !

12. #### Monserrat

if i had the money, i would so get it.
genius idea guys! :D

13. #### Aaron

Hi. I notice that the price shows up as $100 here, and$130 on the store.

14. #### Cj

Why aren’t these in stores yet? Or if they are where can I pick one up?

1. #### Jessica

Hi! We are currently struggling to keep up with the demand for our puzzles. Each one is made from start to finish at our studio in Somerville, MA. Once we catch up on orders we will start selling them to some of our stockists which are small game stores. For now, you can purchase them in our web shop. The link is the in the blog post above. thanks!

As an avid puzzler, I think this is the best invention since sliced bread. As I have no friends this would be the best thing to do whilst I’m sat at home in my dark dingy room, watching antiques roadshow. Why don’t people make useful things like this more often instead of making stupid things like designer clothes and what not. I may even quit may job and have considered entering infinity puzzle competitions along with my fellow avid puzzlers.

16. #### Neil

Any chance you’re planning on a larger size puzzle?

Well,YES, …they are beautiful! And, fascinating!!
ART. Science. Imagination! More!
But….
Too pricey. You can get it, so why not…..!
Just not from me.

Not sure why you call the Klein Bottle an ‘impossible’ shape when the irrepressable Clifford Stoll sells real ones right here:

The 3D embedding of the Klein Bottle intersects itself so it doesn’t actually have the topology of a Klein Bottle. It can only properly be embedded in 4-dimensions.
