About Conway's Game of Life Studio
Conway's Game of Life Studio is a free browser-based simulator for John Conway's cellular automaton. Watch how simple rules create complex, living-like patterns. Draw initial configurations of cells on the grid, press play, and observe the system evolve according to the classic rules: cells with 2-3 neighbors survive, cells with 3 neighbors are born, and all others die. No signup required, and your patterns stay entirely on your device.
This cellular automaton has fascinated mathematicians and programmers for decades because of its ability to produce unexpected behavior from minimal rules. Use the drawing tools to design your own configurations, then let the Game of Life unfold. The tool makes it easy to pause, adjust, and restart, letting you experiment with how slight changes to initial conditions cascade into dramatically different outcomes.
Save your interesting patterns and load them later to study their behavior further. Whether you're exploring cellular automata for the first time or testing known patterns like gliders and oscillators, this free tool runs entirely in your browser with no installation or account needed.

Frequently asked questions
It's a zero-player cellular automaton invented by mathematician John Conway in 1970. Based on four simple rules applied to a grid of cells, the Game of Life produces surprisingly complex behavior including stable patterns, repeating cycles, and shapes that move across the grid. It's a classic demonstration of how elaborate systems can emerge from minimal rules.
Click on the grid to draw cells, then hit play to start the simulation. The automaton evolves one generation per step, applying Conway's rules: a live cell with 2-3 neighbors survives, a dead cell with exactly 3 neighbors becomes alive, and all other cells die. Pause at any time to modify the pattern or reset and try again.
Yes. The tool lets you save your custom patterns locally so you can load them later and continue exploring their behavior. Your patterns never leave your device—everything runs in your browser.
Some classics include the glider (a five-cell pattern that travels diagonally), the blinker (a two-cell oscillator), and the block (a stable 2×2 square). You can also search online for famous patterns like the Gosper glider gun or the Methuselah shapes, then recreate them in the studio to watch them evolve.
