Game of Life

Conway's Game of Life is a cellular automaton with four simple rules:

• Any live cell with 2 or 3 live neighbours survives
• Any dead cell with exactly 3 live neighbours becomes alive
• Every other live cell dies (loneliness or overcrowding)
• Every other dead cell stays dead

How to play:

• Click or tap cells to toggle them alive/dead
• Drag across the grid to paint multiple cells at once
• Press Play to run the simulation, Step to advance one generation
• Use the Speed slider to adjust generations per second
• Load a pattern to try a famous configuration like the glider or Gosper gun
• The edges wrap — patterns that fly off one side return from the other
• Your highest surviving generation count is saved to the leaderboard
