Planet Builder: Space Tycoon

PlanetBuilder is a relaxing strategy game about growing a world from nothing into a thriving civilization. Every day, you make choices that shape your planet's future — from the first rainfall to a sprawling interstellar empire.

BUILD YOUR WORLD Allocate Water, Minerals, Atmosphere, Life Seeds, and Energy to guide your planet through four stages of evolution. Every decision matters — the right resource at the right time can unlock your planet's next chapter.

BUILD GENERATORS Construct generators that keep producing while you're away. Upgrade them, collect passive income, and trigger boosts every few hours for instant bursts of production. Your planet never stops growing.

SHARE A SOLAR SYSTEM Play alongside up to 3 real players in a shared solar system and watch each other's worlds evolve over time.

Send boosts to help a neighbor grow faster Trade resources to fill gaps in your strategy Launch meteor strikes to deposit rare minerals on other planets BUILD AN EMPIRE When your planet reaches Civilization, retire it as a Colony and start fresh — harder, but more rewarding. Retired worlds earn passive coins and permanently boost your generators. Chain up to 5 worlds to build a galactic empire.

DAY & NIGHT BONUSES Your planet changes with the clock. Earn bonus Energy during the day and increased Life Seeds and Atmosphere at night. Playing at the right time pays off.

DAILY CHALLENGES & STREAKS Complete daily challenges, maintain login streaks, and earn coins to spend on generators and upgrades. There's always something to work toward.

A billion years of evolution starts with a single drop of water.
