- The maximum grid is 256x256,
- each byte is 8 horizontal cells,
- the memory is 32x256[8192 bytes long]
-
- The universe of the Game of Life is an infinite, two-dimensional orthogonal grid of square cells,
- each of which is in one of two possible states, live or dead,. Every cell interacts with its eight
- neighbours, which are the cells that are horizontally, vertically, or diagonally adjacent.
- At each step in time, the following transitions occur:
-
- Any live cell with fewer than two live neighbours dies, as if by underpopulation.
- Any live cell with two or three live neighbours lives on to the next generation.
- Any live cell with more than three live neighbours dies, as if by overpopulation.
- Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
