Hi! If you like co-op games, I recommend trying Realm of the Mad God or Diep.io. These are great multiplayer games where you can play with friends right in your browser, without having to download a client. There are also arcade games like [slope run unblocked](https://slopegame-unblocked.com/slope-run/) that offer single player gameplay, but they are just as addictive. All of these games can be found on sites like Crazy Games and Miniclip.
