About this game

Blob.io is a mobile multiplayer online action io game
You start the game as a tiny bacteria, virus (Blob) in a petri dish with agar. You must try to survive by avoiding attacks by bigger players on a nebulous field. Simultaneously, you eat food and become a bigger and bigger blob, until you are large enough to hunt other players.

The game is very immersive and has very active gameplay with a lot of action. All your enemies are real people, so you must find a good strategy to become the biggest virus plague cell on the gamefield! Anyone can become big in one moment, or lose all their progress in the next - so be carefull :) Game mechanics are similar to other io games which you probably already know - but this is not diep io or agar.io macro!

After every game session you get experience points. With those points you level up and unlock some additional features (such as bigger starting mass or exclusive skins). The more mass you make during your game session, the more experience points you get - so don't mope, you will be paid for all your effort. Just like in other io games.

Warning! This game is very addictive and takes form you a lot of effort to survive with so much action.
So if you die in the beginning, be patient, and improve your skills :)

Available game modes in Blob.io:
- FFA
- TEAMS
- EXPERIMENTAL
- INSTANT_MERGE
- CRAZY
- SELFFEED
- DUELS 1v1, 2v2, ... , 5v5
- ULTRA
- DUAL (Multibox dual agar mode)
- PRIVATE_SERVERS (create own private or custom server with own physics)

New game modes with more action are coming soon!
Also we have UNOFFICIAL servers where we change something on a daily basis so you always have new game modes to play! No more same and boring modes as in agar.io offline!

I've had multiple accounts on this game, and I've been playing off and on for years. i would give 5 star but you recently took away xp from the self feed mode, and you also haven't fixed records for years... i love the game as its fun to pass time, but if you dont bring back xp to self feed thats just another reason for people to quit playing. also for god sake, please fix records, ive been waiting in silence for you to fix it for so long and you haven't... Anyways thanks for reading.

Ok it has been quite some time since I have started playing 5 years and I wanted to leave an update, the game is still as fun as when I started. But there are some points I wanted to address. 1. lag - on macro mode the lag can be very bad I have gigabyte Internet but if the servers cant handle the game then its useless, please can you do something about it i have a wired ethernet cable. 2.custom skins plz that way we can customise our blob.

There are so many advertisements, and that's very annoying.
