Agar Io is a super fun online game where you get to control a colorful cell in a big, digital Petri dish. It was created by a developer named Matheus Valadares and released in 2015. The goal is simple: eat tiny pellets and smaller cells to grow bigger while avoiding being eaten by larger cells. It’s like a game of tag, but with cells!
You can play with friends or people from all over the world, and there are different game modes to try out. You can play solo in Free-For-All, join a team, or even compete in a fast-paced Battle Royale. The controls are easy to learn—just move your mouse to guide your cell, press the spacebar to split your cell, and use the ‘W’ key to eject some mass.
Since its release, the game has become wildly popular because it’s easy to play but also full of sneaky strategies. Whether you’re playing on a computer or a touchscreen device, it’s all about growing your cell and having fun!
In this exciting game, you start as a tiny cell in a giant Petri dish. Your main goal is to grow by eating colorful pellets and smaller cells. But watch out! Bigger cells are on the hunt to eat you too. Move your cell around using your mouse or finger if you’re on a mobile device. It’s like a big game of tag where you want to be the biggest cell in the arena!
To get bigger faster, you can split your cell into two by pressing the spacebar. This helps you catch smaller cells quickly, but be careful—splitting makes you vulnerable to larger cells. You can also press ‘W’ to spit out some mass, which can be used to feed friends or trick enemies.
There are different game modes to try out. In Free-For-All, it’s every cell for themselves, and the goal is to become the largest cell on the leaderboard. In Teams mode, join a squad and work together to dominate the arena. Battle Royale mode is a fast-paced challenge where the map shrinks, and only one cell can win. You can also create a private match with friends in Party Mode.
Avoid spiky viruses scattered around the map; they can split your cell into many smaller pieces if you’re too big! Use these viruses strategically by hiding behind them when you’re small or feeding them to split larger opponents.
With simple controls and fun strategies, this game is easy to learn but challenging to master. Whether you’re teaming up with friends or going solo, there’s always something new to discover in this colorful world of cells!
You can play this game directly in your web browser on desktop, laptop, tablet, or mobile.
