Does tribal wars count?

There was also one about forming your own country and passing laws and stuff but I don’t remember the name. It was out around 2002 or so

Played linerider waaaaay too much back in the day.

Krunker.io

When I was in school it was all about Neopets and Adventure Quest.

diep.io and only domination. Stopped going when they put that game mode on some stupid rotation.

Age of War. Was also the last browser game I ever played. Yes it’s old.

Slither.io is definitely my most played browsergame. It gets way more fun with a mod that lets you zoom out a little, as the bigger you get the worse the experience normally gets…

Amazed no one has mentioned Antimatter Dimensions. It’s now on Steam, but was originally on a few sites (I played it on Kongregate). Fantastic, and now with the latest update and the ‘aero’ skin and hidden games, it’s multiple games (Including the original Paperclips) inside one :D

Snake.io is a fun game that i spent so many hours playing.

https://snake.io/ is definitely the browser game that took a lot of my time but I’m having a lot of fun playing it.

I think this old school browser game Utopia counts?

Played it a ton years ago.

cookie clicker, that chromium dino game. I think I also did dark room at some point.
that pokemon browser game. There’s also a taiko game out there. (haven’t checked lately)
