Conway's Game of Life

Invented by mathematician John Conway in 1970, the Game of Life is a cellular automaton where complex behavior emerges from just four simple rules:

• 1. A live cell with fewer than 2 neighbors dies — underpopulation.
• 2. A live cell with 2 or 3 neighbors survives.
• 3. A live cell with more than 3 neighbors dies — overpopulation.
• 4. A dead cell with exactly 3 neighbors is born.

Move your mouse over the grid above to paint live cells. After a moment, the simulation begins and your cells come alive.
