Agar.io vs Paper.io
Agar.io
Agar.io is one of the very first and very popular IO game. Players in this game play as cells that have the unique abilities to eject mass and divide as they fight it out in a 2D arena. Despite being rather minimalistic, the arena itself contains plenty of "food pellets" that you can gobble up to expand your cell mass as well as other obstacles that may either help or obstruct you when you encounter an opponent that you have no way to beat. The game is not only very addictive and competitively casual; it is incredibly strategic and players that excel in it need to have excellent aim as well. You can even customize your cell with a variety of pictures (mainly fun memes or countryn flags), colors and more!Agar.io is definitely a game that will render any productive time you may have into an unproductive one. If you're looking to pass time, this is the game to play!
Paper.io
Paper.io is a competitive and fun IO game that has a gameplay which builds on Slither.io while offering plenty of unique gameplay features of its own. In this game, instead of controlling a worm (or snake, depending on which side of the argument you're in), you get to play as a neverending strip of paper. The strip of paper can be used to circle areas, be it empty areas or areas already captured by other players, that neighbors your own starting block in order to claim them as your own.However, while you're busy trying to capture as much area as you can, other players can run through your "exposed" strip of paper to in some way "cut" through it. If that happens, you die and all the areas you hold gets returned to neutral. There is also the issue of needing to defend your captured area from being "taken" by other players. Things can get pretty heated as your controlled region becomes harder and harder to maintain.
Of course, there are multiple options for you to customize your "colors", including swapping plain colors for more colorful patterns.
Paper.io is without a doubt, an IO game that is just as intensely competitive as it is strategic. The game will definitely keep you coming back for more. If this sounds like a game you'd like to play, be sure to check it out on your browser or in your nearest app store.
