A field guide to growth

1. Grow. Begin the experiment, choose a cell percentage, then click open space. Your border advances toward that point until the sent cells run out.

2. Nourish. Capture gold diamonds for +7 cells/second each. More territory also grows your income and storage.

3. Compete. Click a rival to advance toward them and attack when your borders meet. Enemy tiles cost more cells. A new order redirects your unspent advancing cells.

4. Adapt. Energy regenerates at 2 per second, up to 100. Growth surge (35 energy, 22s cooldown) doubles income and boosts advance speed for 8 seconds. Cell membrane (40 energy, 26s cooldown) triples enemy capture costs for 10 seconds. Spore jump (60 energy + 50 cells, 30s cooldown) plants an outpost on open space within 22 tiles of any of your territory, then automatically expands using your selected send percentage of remaining cells. This redirects your previous expansion order. Growth stops when the sent cells run out; you can click elsewhere to redirect it. All colonies can use abilities.

5. Race. Early pulsing gold rings are temporary nutrient blooms: capture one within 24 seconds for 120 cells and 30 energy. Once 80% of the playable dish is claimed, blooms retire and flashpoints begin. Each flashpoint marks one capturable tile with a 10-second warning; its hold timer starts when the warning ends. Keep that exact tile continuously for 12 seconds. Ownership changes reset the hold, and warning ownership does not count. Success awards 8 seconds of normal income (surge excluded) and 30 energy, within normal caps. Unclaimed markers expire and move.

Keyboard: Q for surge, W for membrane, E to aim a spore, Escape to cancel. Focus the map, use arrow keys to aim, Enter to send, and P to pause solo games. Multiplayer rooms run continuously for up to 30 minutes; leaving does not pause other players. Reopening this tab restores your session while the room exists (up to two hours). Capture 60% or eliminate every rival to win.
