A free online Conway's Game of Life simulator. Click cells to create living organisms, place preset patterns (Glider, Pulsar, Gosper Glider Gun), and watch them evolve through generations. The classic zero-player cellular automaton where life, death, and survival emerge from simple rules. Features adjustable speed, step-by-step mode, and live population count.
Click cells to toggle them alive or dead.
Choose a preset pattern or draw your own.
Press Start to begin the simulation.
Watch emergent patterns evolve through generations.
Any live cell with 2-3 neighbors survives. Any dead cell with exactly 3 neighbors becomes alive. All other cells die or stay dead.
Try the Glider (moves diagonally), Pulsar (oscillating), or Gosper Glider Gun (creates infinite gliders).
