THE BIOME GAME
BUILD • BALANCE • SURVIVE
🐾Your starting budget and daily refills depend on difficulty — and refills shrink over time, so your ecosystem must learn to sustain itself!
🌿Click or drag animals from the right panel onto the map. Hover any animal or plant to see what it eats, what hunts it, and its limits.
⚖️Keep predators and prey balanced. Too many predators and they'll starve. Too much prey and plants disappear.
🌪️A random disaster strikes periodically — harder difficulties mean more frequent and deadlier events. Each disaster gets worse than the last!
📅You can place up to 10 of each species per day. Resets every game day — plan carefully!
🏆Score points by maintaining diversity, keeping balance, and letting animals live to old age ⭐. Stay active — scoring pauses if you go idle!
