Imagine a grid, stretching endlessly in all directions, where tiny squares flicker between life and death, following a few simple rules. This is Conway’s Game of Life, a cellular automaton created by mathematician John Horton Conway in 1970. It’s not a game you play with a controller or a keyboard—it’s a zero-player game, meaning you set up an initial pattern, and the grid evolves on its own. Each square, or cell, can be alive (filled) or dead (empty), and its fate depends on its eight neighboring cells. The rules are beautifully simple:
-
A live cell with fewer than two live neighbors dies from loneliness.
-
A live cell with two or three live neighbors survives.
-
A live cell with more than three live neighbors dies from overcrowding.
-
A dead cell with exactly three live neighbors comes to life.
These rules create a universe where patterns grow, shrink, or transform in unexpected ways. From still lifes that stay frozen to oscillators that pulse rhythmically, the Game of Life is a playground for discovering patterns. One of the most exciting discoveries in this digital universe is the Copperhead, a spaceship that zips across the grid at a unique speed. Let’s dive into what makes the Copperhead so special and why it’s captured the imagination of math enthusiasts, programmers, and hobbyists like me.
What Is the Copperhead?
In the Game of Life, a “spaceship” is a pattern that moves across the grid, reappearing in a new position after a set number of generations. The Copperhead, discovered on March 5, 2016, by a user named “zdr” on the ConwayLife.com forums, is a small but remarkable spaceship. It travels at a speed of c/10, meaning it moves one cell every ten generations, orthogonally (straight up, down, left, or right). What makes it stand out is its compact size, high period (it takes ten generations to return to its original shape), and its unexpected emergence in a field dominated by slower or larger spaceships.
The Copperhead’s pattern is surprisingly simple, made up of just 28 live cells in its initial configuration. Here’s a glimpse of its structure (visualized as “O” for live cells and “.” for dead cells):
.OOOO.
......
.O..O.
O.OO.O
O....O
......
O....O
OO..OO
OOOOOO
.O..O.
..OO..
..OO..This compact shape hauls a “block” behind it, which leads to fascinating interactions with other patterns. When I first saw the Copperhead in action, I was mesmerized by how such a small cluster of cells could zip across the grid with such precision, like a tiny digital snake slithering through a pixelated desert.
The Discovery of the Copperhead
The story of the Copperhead’s discovery is a testament to the collaborative spirit of the Game of Life community. The user “zdr” used a modified version of a search program called zfind, which is based on a depth-first search algorithm, to uncover this gem. On the same day, enthusiasts on the ConwayLife forums were buzzing with excitement, proposing names like “blockhauler,” “decapod,” and “cuttlefish” before settling on “Copperhead” for its sleek, snake-like movement. The name stuck, and the pattern quickly became a star.
What amazed me was how fast the community built on this discovery. Within hours, a glider synthesis—a way to construct the Copperhead using gliders (another type of spaceship)—was proposed by a user named praosylen. Another user, Tanner Jacobi, suggested an even more efficient synthesis using a pattern called a fumarole. By the end of March 2016, Simon Ekström added a “sparky tagalong” to the Copperhead, creating a variant called the Fireship, which spits out sparks as it moves. These rapid developments showed me how a single discovery can spark a chain reaction of creativity in the Game of Life world.
Why the Copperhead Matters
The Copperhead isn’t just a cool pattern; it’s a milestone in the Game of Life’s history. Most spaceships, like the lightweight spaceship (LWSS) or the glider, move at speeds like c/2 or c/4. The Copperhead’s c/10 speed was the first of its kind, proving that the Game of Life could support a wider range of velocities than previously thought. Its small size—only 28 cells—made it even more surprising, as high-period spaceships are often larger and more complex.
For me, the Copperhead’s significance goes beyond its speed. It’s a reminder of how simple rules can lead to complex, unpredictable outcomes. When I first started experimenting with the Game of Life, I spent hours tweaking patterns on graph paper, watching them evolve in unexpected ways. The Copperhead’s discovery felt like a personal victory for the community, showing that even decades after Conway’s creation, there were still new frontiers to explore.
How the Copperhead Works
To understand the Copperhead, let’s break down its mechanics. The pattern moves orthogonally at c/10, meaning it shifts one cell every ten generations. Its period of 10 means it cycles through ten distinct shapes before returning to its original form, just shifted in position. This high period makes it trickier to simulate than faster, lower-period spaceships like the glider (period 4).
The Copperhead’s ability to “haul” a block behind it opens up unique possibilities. For example, it can interact with other spaceships, like gliders or middleweight spaceships, in clean ways—either absorbing them or transforming them into new patterns. Dean Hickerson, a prominent figure in the Game of Life community, used this property to build a “sawtooth” pattern, where the Copperhead turns a heavyweight spaceship into a loaf (a type of still life). Watching these interactions unfold in a simulator like Golly is like watching a tiny universe come to life, with each pattern playing its role in a cosmic dance.
My Personal Journey with the Copperhead
As someone who’s been fascinated by cellular automata since I stumbled across the Game of Life in a high school math class, the Copperhead holds a special place in my heart. I remember downloading Golly, a free software for running Game of Life simulations, and spending late nights experimenting with patterns. When I first loaded the Copperhead, I was struck by its elegance. Unlike the chaotic explosions of random configurations, the Copperhead moved with purpose, its block trailing behind like a loyal companion.
I decided to experiment with it myself, placing Copperheads in different arrangements to see how they’d interact. One memorable moment was when I set up two Copperheads moving toward each other. Instead of crashing, they passed through each other cleanly, leaving behind a few stray cells that eventually stabilized. It felt like I’d discovered a secret handshake in the Game of Life’s universe. These experiments taught me that the Copperhead isn’t just a pattern—it’s a tool for exploring the boundaries of what’s possible in Conway’s world.

The Copperhead in the Broader Game of Life Community
The Game of Life has a vibrant community, with forums like ConwayLife.com and tools like Catagolue (a database of patterns found in random “soups”) driving new discoveries. The Copperhead’s emergence in a soup search on April 4, 2016, by a user named Apple Bottom was a big deal—it was the first non-standard-speed spaceship to appear naturally in such a search. This rarity underscores the Copperhead’s uniqueness and the power of computational tools in uncovering hidden gems.
The community’s enthusiasm for the Copperhead didn’t stop at its discovery. It ranked second in the 2016 Pattern of the Year competition on ConwayLife.com, just behind the caterloopillars (another fascinating pattern). The Copperhead’s ability to inspire new constructions, like puffers and rakes, shows its versatility. For me, browsing the ConwayLife forums feels like joining a global puzzle-solving club, where every new pattern is a piece of a larger mystery.
The Fireship: A Sparky Cousin
One of the most exciting developments from the Copperhead was the Fireship, discovered by Simon Ekström on March 20, 2016. The Fireship is a variant of the Copperhead with a tagalong component that emits large sparks as it moves. This addition slightly alters two of the Copperhead’s phases, making it a distinct spaceship in some classifications. The Fireship’s sparks enable the creation of puffers (patterns that leave debris behind) and rakes (patterns that emit gliders), expanding the Copperhead’s utility.
When I first ran the Fireship in Golly, I was thrilled by the sparks flying off its tail. It felt like watching a comet streak across the grid, leaving a trail of digital stardust. The Fireship’s discovery showed me how a single pattern can evolve into something even more dynamic, keeping the Game of Life fresh and exciting.
The Math Behind the Magic
The Copperhead’s c/10 speed and period-10 cycle are rooted in the Game of Life’s mathematical elegance. The rules create a balance between growth and decay, allowing patterns like the Copperhead to emerge as stable, self-propelling structures. Its discovery via zfind, a depth-first search program, highlights the role of computational power in modern mathematics. I’ve dabbled in coding my own Game of Life simulators in Python, and seeing how algorithms like zfind can sift through billions of configurations to find something like the Copperhead is awe-inspiring.
The Game of Life is also Turing complete, meaning it can simulate any computation a computer can perform, given the right patterns. The Copperhead, while not a universal constructor itself, plays a role in this computational universe. For example, it can be used in complex constructions like sawtooths or signal converters, as noted by users like Dean Hickerson and James Pascua on the ConwayLife forums.
