How to play Space.io?

In each round, only the best space pilot will survive. Dodge the asteroids and pick up power boosters and health top-ups to gain the upper hand. 

Aim and fire at your opponents to take them down. Once you’ve got them in your sights, your cannon will lock onto your target automatically.

During each round, you save up points to unlock new spacecraft and increase your player level and ranking. Dominate the battlefield and claim the top spot!
