Rush Mode (also known as Rush Match) is a game mode added to the mobile version of Agar.io in July 2016. This is the second Game Mode added to the mobile version after Classic Mode. Rush Mode is not yet available for the browser version of the game.
In this game mode, a cell has 5 minutes to gain as much mass as possible. Single spawn Rush Mass boosts are available for 9 coins (+20 Mass) or 19 coins (+40 Mass). Viruses are red and require only 3 ejected mass balls to create a new one. Cell mass is shown in decimal numbers, unlike other game modes. After the match ends, the leader board is displayed with the Top 10.
Changes and UpdatesEdit
Cell mass is now displayed in whole numbers. The time before a cell merges has been reduced.
You gain more XP in this mode.The March 2017 update to the mobile app brought several more key changes to Rush Mode. The size of the game field was significantly reduced. Also, a timer for "Estimated Time" is now displayed during the pre-match "Gathering players …" screen.
