TWO LINEAGES. ONE WORLD.
Plant a beginning. Watch life unfold.
A SMALL GUIDE
Choose a lineage and paint neighboring cells while paused. Press Run to watch the world evolve, or Step to advance one generation.
Randomize selects a percentage of the 3,456 cells, rounded to the nearest cell. Each selected cell gets an independent random live/dead state and ancestry; all other cells keep their values. It pauses and restarts at generation 0. At 0%, nothing changes.
A living cell survives with two or three living neighbors. An empty or dead cell is born with exactly three, inheriting their majority lineage. All other living cells die, leaving their ancestry behind.
Erase kills a cell but keeps its history. Clear cell removes both. Reset clears the whole world.
Drag to paint. Use two fingers to pan or pinch to zoom. On desktop, select Pan to move the board and use the mouse wheel to zoom. S Pen works directly.
Keyboard: arrows select a cell, Enter paints, Space runs or pauses, and Ctrl/Cmd+Z undoes a stroke. Shift+Ctrl/Cmd+Z redoes it. Simulation steps clear editing history.
The world has fixed dead boundaries. Cells never wrap around its edges.
This clears every living cell, its history, and the generation counter.
