Grow as fast as you can! Multiplayer online game where you play as a blob that consumes literally everything in its way! Start the game being a tiny blob and eat the smaller ones to grow rapidly. It takes a lot to survive as you should avoid attacks of bigger blobs as they are eager to eat you as well. When your blob is big enough to pose a danger for other players, start hunting them! The game is quite immersive: you should constantly grow but don't forget to escape from your rivals, as all of them are real people. Every player can become significantly bigger or lose all the progress in a moment, be careful :). After every game session, you get experience points depending on the finite size of your blob and session time. With these points, you can get the level up and unlock some additional features (e.g. bigger initial mass or exclusive skins). The more actions you make during a game session, the more experience you get, so don't lapse into despondency, you will be rewarded for all your efforts! If you die at the very start, be patient, improve your skills and try again :) Game modes: - FFA - Teams - Experimental - InstantMerge - Crazy - Macro - SelfFeed - 2vs2 - Ultra - Battle Royale - Minions - Dual - Unofficial modes - Private/Custom Unique features: - video replays - customizations - separation by the regions - friends invitation system - animated and custom skins Our community: Discord: http://disc.blobgame.io/ Instagram: @blob.io_official Linktree: https://linktr.ee/blob_io Terms and conditions: https://blob-terms-and-conditions.blogspot.com/2018/12/blob-io-terms-and-conditions.html Privacy Policy: http://blob-devour.blogspot.com/2017/08/privacy-policy-this-policy-will-explain.html
