Lab · Game
Game of Life is a free online tool that lets you paint Conway's cellular automaton, run it at any speed, and load famous patterns like gliders and the Gosper Glider Gun — with nothing to install and nothing leaving your browser.
Controls
Generation 0 · 0 live cells
Empty board — paint some cells, load a pattern, or randomise.
Board — 48 × 32
Drag to paint or erase · tap a cell to toggle it · gliders wrap around the edges when wrap-around is on.
Every cell follows two rules each generation: a live cell survives with 2 or 3 live neighbours, otherwise it dies; a dead cell comes alive with exactly 3 live neighbours. That is all — yet gliders crawl, blinkers blink, and the Gosper Glider Gun fires a new glider every 30 generations, forever. With wrap-around on, the board is a torus: neighbours wrap across the edges, so a glider that flies off one side re-enters on the other. With it off, the edges are dead borders. Everything runs locally in your browser — your board is never sent anywhere.
