THE LAWS OF YOUR LITTLE WORLD
Each cell can be red, green, blue, or empty. Every tile updates together, once per generation.
Tap a tile to cycle: red → green → blue → ∅ empty → ✳ any state.Neighbor positions matter; patterns don’t rotate.
A matching rule with more specific input tiles wins over one with fewer. Empty is a specific state, not a wildcard. Equally specific conflicting overlaps aren’t allowed. Unmatched cells keep their color.
Red follows green, green follows blue, blue follows red.
Your rules and world save in this browser. Importing changes rules only. The finite grid never wraps; missing neighbors match only wildcards.
