About

Conway's Game of Life: a grid of cells that live or die by three simple rules each generation. Click cells to draw, randomise a soup, or step one frame at a time and watch gliders crawl across the board.

How it works

A flat Uint8Arraygrid (wrapping at the edges) is advanced by counting each cell's eight neighbours: a live cell survives on 2–3, a dead cell is born on exactly 3. Rendered to a <canvas>, stepped on an interval. No backend.
