Conway's Game of Life

A cellular automaton with just four rules. Click cells to toggle, press Run to evolve, load classic patterns, or randomize the grid. All simulation runs locally in your browser.

Rules

  1. Any live cell with fewer than two live neighbours dies (underpopulation).
  2. Any live cell with two or three live neighbours lives on.
  3. Any live cell with more than three live neighbours dies (overpopulation).
  4. Any dead cell with exactly three live neighbours becomes a live cell (reproduction).
