There is this new game that is totally free and does not need to be downloaded called "agar.io" This game was launched in April of 2015 and has gone VIRAL on social media. The point of it is you are a cell, (Inside of a body not a prison) and you try to eat other cells that are smaller than you. You have to avoid the bigger guys. Your 2 main abilities are 1, press w to eject some mass (commonly used for teaming) and 2 If you press space half of your body will shoot out. (commonly used for eating guys that are faster, but you are 2x bigger than)
Don't play it on a mobile device, the app version is super laggy. Play it on a computer and you won't lag as much.
One time I was 7th on the leaderboard once on the computer, but I'm pretty sure I then ate one of those spikey green balls by accident then I started to get smaller and smaller until someone else ate me. I knew about Agar.io when I saw Pewdiepie play it :D Then I got it on my Ipad Mini too, even though its really laggy :\
I hope everyone types agar.io with an A in agar.io. agor.io is a screamer link, i've misspelt it before -_- ^never use this if someone says.
I also have a top score of 8000, though I've never made it to 1st on the leaderboard. It's fun to play, but losing agar.io is even more infuriating than losing the game. (also, teaming is a terrible idea. Don't use it. Instead, eject particles at the green wavy things to make them split and destroy your enemies that are hopelessly bigger than you)
