Conway's Game of Life

Click a cell to bring it to life, draw a starting pattern across the grid, then hit play and watch the colony evolve on its own. Conway's Game of Life runs on just four rules — cells live, die, or are born based on how many neighbors they have — yet those rules produce gliders that crawl across the board, oscillators that pulse in place, and structures that can surprise you even after dozens of runs.

There's no winning or losing here. The interest is in experimentation: try a dense cluster, try a sparse scatter, try recreating a classic pattern like the R-pentomino and see how long the chaos lasts. It belongs to a small category of interactive simulations that reward curiosity more than reflexes. Flocking Boids covers similar ground if you're drawn to emergent behavior from simple rules, but with moving agents instead of a static grid.

A larger screen helps here because the full grid takes up significant space — more cells visible at once means you can watch large patterns unfold without losing detail at the edges.
