Everything you need to know before diving into the Spacy galaxy.
What exactly is Spacy?
Spacy is a real-time multiplayer space strategy game playable straight from your browser. You build an interplanetary empire, research technologies, command fleets and clash with other players across a persistent galaxy.
Is Spacy really free?
Yes, Spacy is 100% free. No credit card required at signup, no pay-to-win mechanic blocking progression, and no feature locked behind a subscription.
Do I need to download or install anything?
No. Spacy is a fully web-based browser game: Chrome, Firefox, Safari, Edge — any modern browser works. No install, no client to update, no heavy downloads.
Is Spacy a game like Ogame?
Spacy follows the great tradition of Ogame-style space strategy games: empire management, planetary economy, scientific research, real-time fleet battles. Spacy modernizes the formula with original mechanics (equipment modules, expeditions, bounties).
Can I play on mobile or tablet?
Spacy's interface is responsive and works on tablets and modern smartphones. The experience is best on a wide screen, but no feature is desktop-exclusive.
Is multiplayer truly real-time?
Yes. Fleets travel in real time across the galaxy, buildings construct in real time, and battles resolve in seconds once fleets make contact. The game keeps moving even while you're logged out.
