Slither.io

Take the classic Snake game from the golden Nokia days, add a multiplayer mode, put it on steroids, and what you get is Slither.io. Your goal is simple - collect coloured balls to grow in size, and avoid being trapped by other snakes. This game is a live multiplayer, so all players around the world are playing in realtime, and you must cut the bigger snakes’ paths to take them out and become the biggest and baddest on the scoreboard.
