Claim more hexes than your opponent. Score = occupied hexes + piece bonus.
Organic moves first, then players alternate. If one faction has no valid moves, the other may continue placing pieces.
Branches / Veins
3 hex · +1 pts
Must connect to exactly one edge of own Branch/Vein and/or one edge of the Core. May touch at most one edge of enemy Branch/Vein.
Spores / Shards
1–2 hex · +1 pts
Must be adjacent to at least one own piece.
Leaves / Prisms
3–4 hex · +2 pts
Must be adjacent to an own Branch/Vein.
Fruits / Clusters
5 hex · +5 pts
Must be adjacent to an own Branch/Vein. Cannot touch the Core or an own Fruit/Cluster.
Enclosures
If a player's connected pieces are surrounded, meaning they can no longer reach the edge of the playing field through further growth, they are considered smothered and will be removed from the board. The points scored by these pieces are deducted. Removed pieces are permanently eliminated from the game.
Traps
Before placing a Fruit or Cluster, click the ☣/☢ badge to designate it as a Poisonous Fruit or Radioactive Cluster. A poison piece cannot be placed adjacent to any opponent piece. Once placed, it becomes active: if the opponent later places a piece adjacent to it, that piece is immediately destroyed.
End of Game
The game ends when neither faction can place any more pieces, when the trailing faction runs out of moves, or when one faction resigns.
