Conway's Game of Life in 3D: a zero-player cellular automaton where extraordinarily complex, self-organising structures emerge from two simple rules about birth and survival.
Each 3D cell follows two rules: a living cell survives with the right number of neighbours; a dead cell is born if it has exactly the right count. Simple rules produce self-replicating structures, gliders, and stable oscillators.
Click cells to toggle alive/dead. Press Play to run. Load famous presets like gliders or spaceships. Adjust generation speed and birth/survival neighbour thresholds with sliders.
John Conway proved that the 2D Game of Life is Turing-complete — it can compute anything a real computer can. In 2009, a player built a working model of Conway's Life running inside the game itself.
