How to play

What is a still-life in Still Pond?

A still-life is a Conway's Game of Life configuration where applying GoL rules one step produces exactly the same grid. Live cells with 2 or 3 live neighbors survive; dead cells with exactly 3 live neighbors are born; everything else dies. A still-life therefore does not change between timesteps.

How do you play Still Pond?

Tap each blank cell to flip it between empty (◻) and filled (●). Your goal: configure all cells so the resulting grid is a still-life. Cells already given cannot be changed. There is exactly one correct solution per puzzle.
