This is the flat, top-down companion to the 3D Game of Life simulator, which extrudes the same automaton into voxels, height maps and a sphere. Here the grid is drawn as a genuine 2D pixel lattice — no camera, no depth, no rotation — so every live cell is a flat colored square and the whole board is visible at once, the way Conway's original automaton was always meant to be read.
- Grid size — width and height of the toroidal (wrap-around) cell lattice.
- Density % — fraction of cells seeded alive on a random start.
- Speed — generations computed per second while playing.
- Pattern — load a famous starting configuration, auto-centered on the grid.
- Rule — the birth/survival neighbour-count thresholds (B/S notation).
- Click or drag directly on the grid to toggle cells by hand, then press Play.
