Agma.io — Play Free Online

Action & Shooting

Agma.io is a cell-eating action game where you grow by eating smaller players and dodge bigger ones. Play it free in your browser, no download needed.

Agma.io is an action .io game in the cell-eating tradition: you start as a tiny blob in a crowded arena, swallow whatever is smaller than you, and try to avoid whatever is bigger. Every other blob on the map is a real opponent or a target, so the mood changes from second to second, from calm grazing to a sudden chase.

It is a very different pace from Doodle Jump. There is no ground to fall to and no fixed goal line. A session lasts exactly as long as you stay uneaten, and the score is simply how large you got. That makes it a good fit for a few minutes between longer games, and the browser build means there is nothing to install.

How to play

Move with the arrow keys or WASD, and use the mouse to aim and to pick options on the menus. On a phone, you tap and swipe instead. The core loop is the same in every round:

Early on, collect the small stationary pellets scattered around the map. They are safe and every one makes you slightly bigger.
Once you have some size, start going after smaller players. Bigger cells move more slowly, so approach from an angle they are not watching.
When a larger player turns toward you, stop collecting and put distance between you and them.

Tips

Stay near the edges of the crowd while you are small. Most early deaths come from drifting into the middle of the map.
Judge size before you commit. A cell that looks just slightly bigger than you is still able to eat you outright.
Do not chase the same target across the whole map. Break off and collect pellets instead of running into a larger player on the way.
Play a calm opening. A steady start with few risks usually beats an aggressive one that ends in the first minute.
