Agar.io

Agar.io is a massively multiplayer top-down strategy browser game. In Agar.io, the player manipulates a circular cell using the mouse and keyboard keys. The object of the game is to grow the cell by swallowing non-player cells that are randomly scattered around the map. Other players whose cells are smaller than the player's can also be swallowed. Originally a browser game, Agar.io was submitted to Steam Greenlight and subsequently "greenlit" by the community. The developers stated that they plan to add more features that are not available in the web version of the game. Agar.io has quickly become popular worldwide. Before the 2015 Turkish elections, Agar.io was used in Turkey for political reasons; some political parties also used Agar.io on election posters as a symbol of support. Players can also use skins.
