How to play
- Goal
- Protect the greenhouse by connecting and growing plants before each insect wave.
- How it ends
- Clear every wave with the greenhouse intact to win; lose when its health reaches zero.
- Record
- Your highest defence score is kept for each expedition, with its holder name.
- Choose a seed packet, then tap an empty soil cell. Start beside the brass WATER inlet: occupied pots touching along a side carry water vertically and horizontally. A gap leaves the plants beyond it dry. Every plant carries water.
- Attackers fire toward the right along their entire row. Seedspitter focuses one insect, Frostbell slows most foes, and Burstmallow splashes nearby insects while piercing armour. A watered Sunbud adds damage to adjacent attackers. Moths resist slow.
- Tap a planted pot to Grow it once or Uproot it for a full refund. Clover is a cheap conductor and does not grow. Launch locks your arrangement while the wave plays out. Each cleared wave supplies 30 more seeds; rearrange freely before the next one.
- Keep the greenhouse above zero health for all three waves. Score remaining health ×1,000, insects stopped ×10 and spare seeds ×5. Wave preview lists the arrivals and enemy stats. Preparation has no countdown.

Every expedition has a verified winning defence; no unique or optimal plan is promised. All expeditions are open. Progress and named personal bests save in this browser. Ranked victories require uninterrupted combat; opening a panel or hiding the page during combat, or restoring a saved expedition, keeps a local score. Planning between waves is untimed. Ranked defences keep their replays. Effects, music and reduced motion have separate controls. No ads or analytics inside the game.

About Bloom Battalion
The last garden has wheels. Guide a copper-and-glass greenhouse through sunlit woodland, fern marshes and lavender dusk, protected by a small army of living plants.
Build a connected root network, then launch the wave and watch Seedspitters fire, Frostbells swing and Burstmallow scatter pollen. Cheap Clover carries water across the soil; Sunbuds strengthen their neighbours. Dry plants cannot fight.
Thirty open expeditions offer three waves each. Stones change the bed, insect formations change the lanes, and new seeds between waves let you grow or completely rearrange your defenders. Full refunds reward experimentation.
