the game is made of an infinite grid (i had to make it finite or my computer would explode.) each square is a cell. it can be alive or dead (when you start the game they will all be dead) click to toggle between live and dead. press and hold space to run the game it runs on these four simple rules 1) Any live cell with fewer than two live neighbours dies 2) Any live cell with two or three live neighbours lives 3) Any live cell with more than three live neighbours 4) Any dead cell with exactly three live neighbours becomes a live cell
