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.
