## What is Cell Pulse Flash?

Cell Pulse Flash gives you a set of seed points and asks you to balance the space between them.

Each seed owns a Voronoi cell — the region of the canvas closer to that seed than to any other. Together the cells tile the entire surface, interlocking like stained glass, their borders running exactly where two seeds are equidistant. The cells are coloured by how balanced they are. A cell with too much area is dark. A cell with too little area is muted. A cell with exactly its fair share of the canvas glows at full brightness.

The goal is simple to state and genuinely difficult to achieve: drag the seeds until every cell glows equally.

Moving a seed toward a large dark neighbour reduces that neighbour's area and expands your own. But expanding your own cell darkens it. The balance propagates — adjusting one seed shifts the cells of every seed adjacent to it, which then need their own adjustment. With five seeds the constraint chains are manageable. With nine seeds, finding equilibrium requires systematic thinking about the geometry of the whole diagram rather than local adjustments.

The visual feedback is intrinsic. You do not need a score or a bar to know you are improving — balanced cells literally glow brighter. The diagram tells you where to drag. Move toward the dark regions. Pull your seed back when your own cell dims. The puzzle teaches its own solution through pure visual response.

This is a Voronoi diagram — a mathematical structure that appears in crystal formation, animal territorial distribution, cell biology, urban planning, and the distribution of cone cells in the human retina. The centroidal Voronoi tessellation you are finding — the specific arrangement where every seed sits at the centre of gravity of its own cell — is one of the most geometrically elegant configurations in computational geometry. It emerges in nature wherever a system of competing regions settles into equilibrium.

When the balance threshold is crossed, the mosaic erupts. Every cell simultaneously jumps to maximum brightness — a single flash where the entire diagram pulses with equal light, like a stained-glass window catching direct sunlight for one perfect moment. Then it settles. A new puzzle assembles with more seeds, tighter tolerances, and more complex interdependencies.

No ads. No timers. No prior knowledge of geometry required. The cells show you everything you need to know.

Just the seeds, the space between them, and the light that arrives when everything is equal.
