Slither.io

Slither.io is the best game in history. It's very simple. You can eat glowing orbs, use boost speed, and crash other snakes. And there's two ways to play it: Play Online! And Play Against A. I. Even there's a cool collection of skins and give the snake a username, and there's cosmetics for the skins, which make them cooler, funnier, and better. Pretty sure that the unnecessary things are the servers. The game uses servers for i don't know, and if you choose low servers, they make the gameplay lag. But anyways, it's a very, very cool game. I love it so much, it's the best, and no game can hit this game.
