PolyPine

PolyPine is a forest-building game where you plant trees, add animals and shape the terrain to create an ecosystem. The forest changes as trees grow, animals interact with it and natural disasters affect the environment.

Grow a forest

Trees pass through five stages: seed, sapling, adult tree, dead tree and fallen trunk. Each stage creates a different habitat for plants and animals. You can build forests across hills, lakes, mountains, fjords and wetlands, and terraform the terrain to shape it further.

Add and interact with animals

Animals have specific habitat needs that you must meet before adding them. Squirrels need trees, for example, while butterflies need flowers. Clicking animals triggers behaviors that affect the ecosystem: moose fertilize the soil with their droppings, voles eat tree roots and damage trees, and foxes hunt other animals.

Natural disasters

Forest fires, storms and bark beetle swarms affect the forest in different ways. You can use these events to your advantage as you work to create a thriving ecosystem.
