Agar.io

Agar.io (or just Agar) is a shitty free online browser game that consists of colored balls, known as "cells" that move around on a grid with invisible borders. The main objective of the game is to become the largest cell in the server by eating up smaller cells, and/or stationary colored dots, known in the game as "food", all without getting eaten up yourself. Provided you don't get preyed on by other people seconds after you spawn, you will get a place on the high scores board if you become one of the top ten largest cells in the server; however, YOU probably won't even get on the 11th spot in the top ten. Smaller cells also cannot eat up any cell that is larger than them, nor can two similarly-sized cells eat each other up. You use your mouse to move around, and split by pressing the dubya key. Oh, and don't touch those stationary green squishy things; those will fuck your shit right up and likely cause massive butthurt on your part while you watch the other faggots on the server gobble you up like a fly on shit.

Skins

Skins play a large part in Agar.io; in fact, they have several shitty skins if you enter a certain nickname for your cell, such as Hitler, or Stalin. Some people use these skins as a method of trolling, however their attempts often fail miserably and often end up rage quitting due to getting eaten up repeatedly over and over again.

You can also use custom skins for your cells, but you need to host your own server, or some shit in order for you to use them.

Slither.io

Slither.io is a shameless ripoff of Agar.io which managed to become popular enough to rival the game that inspired it. This game has you play as a snake instead of a cell, eating tiny glowing orbs to grow longer and attempting to get other snakes to run into you from the side. When you die, you turn into a trail of glowing orbs that other snakes will immediately cannibalize. Although snakes can have patterns, they do not have skins with the same level of detail that Agar.io's cells have.

Petridish.pw

[petridish.pw/en/ Petridish] is a Russian version of agar.io that has many more features aswell as less cancerous players and your own skins. If is the exact same concept as agar.io except it has multiple gamemodes and you can choose which servers you want to play on. Trolling is extremely easy and it has a fair share of glitches.
