Totalistic Cellular Automata

Beyond Conway's Life — explore birth/survival rules in 2D outer totalistic automata

Birth rule (dead cell)

Survival rule (live cell)

Presets

Generation: 0
Population:
Rule B/S:

Each cell counts its 8 Moore neighbors. Birth: dead cell with B neighbors becomes alive. Survival: live cell with S neighbors stays alive.

Conway's B3/S23 is one of ~262,000 possible outer-totalistic rules. Click canvas to paint cells.
