Frequently Asked Questions
Is Agar.io completely free to play?
Yes! Agar.io is 100% free to play with no downloads, installations, or payments required. Simply open your browser, enter a nickname, and start playing immediately. Join millions of players in the ultimate cellular survival experience!
Can I play Agar.io on my mobile device?
Absolutely! Agar.io is fully optimized for mobile gameplay with responsive touch controls. Play seamlessly on smartphones and tablets with intuitive swipe controls for movement and tap controls for splitting and mass ejection.
How do I grow bigger and stronger in Agar.io?
Growth comes from consuming mass: eat food pellets scattered around the map, absorb smaller players, and collect ejected mass from other cells. The more you consume, the larger you become. Remember: size equals power, but larger cells move slower, creating strategic trade-offs.
What happens when I split my cell?
Splitting divides your cell into two equal halves, with one half shooting forward at high speed. This is perfect for catching smaller prey, escaping danger, or performing surprise attacks. Your split cells will automatically recombine after approximately 30 seconds.
How does the leaderboard ranking system work?
The leaderboard displays the top 10 largest players in your current game session, ranked by total mass. Grow your cell to climb the rankings and see your name among the arena's elite. Reaching #1 makes you the ultimate cellular champion!
What are viruses and how do I use them?
Viruses are the large green spiky circles scattered across the map. When a large cell touches a virus, it explodes into many smaller pieces. Use viruses strategically as shields, hiding spots, or feed them mass (using W) to make them burst and split larger opponents!
What happens when I get eaten?
When a larger cell absorbs you, you lose all your mass and must respawn as a tiny cell. Don't get discouraged! Each death is a learning opportunity. Analyze what went wrong, develop better strategies, and come back stronger for cellular domination!
Can I play with friends or team up with other players?
While Agar.io doesn't have official team features, players often form temporary alliances or coordinate through chat. You can work together to take down larger opponents, share mass, or protect each other. However, remember that in the cellular arena, trust is temporary!
