Snowball.io

Snowball.io is a great multiplayer game where you will be trying to blast other players from the playing field. You can do that by making a gigantic snowball. When it gets big enough, let go of the mouse button and launch it at your enemies. Ideally, try to aim so that you knock them out of the playing field. If you manage to do just that, you will be able to focus on fewer opponents. At the same time, you will grow a bit bigger and that will only help you. The last one to stay at the playing field wins, so try hard.
