Agar.io

Agar.io , the legendary game that started the whole .io craze, invites players to a microscopic battlefield. You start the game as a tiny cell and slowly grow by eating the immobile plankton on the map. Once you've gained enough mass, the real fun begins: devouring other real players who are smaller than you!

Agar.io is more than just a simple eating game; it offers a deep tactical structure. The viruses, which appear as green and spiked shapes on the map, are safe havens where you can hide when you're small, but when you reach enormous sizes, they transform into traps that shatter your cell into dozens of tiny pieces if they hit you. You can trap your opponents by launching small pieces of your mass with the 'W' key, or you can enlarge the viruses and detonate them on your enemies. The 'Space' key splits your cell in two, allowing you to leap forward and suddenly swallow your fleeing small opponents.
