Are there any free browser games that you can play with friends e.g. Cards Against Humanity, Type racer Just some simple games that preferably does not require any downloading.
That's pretty vaguely termed, so there are a lot of options . I would actually suggest something very 'old', and which you can't actually play against eachother directly, but you challenge eachothers' scores in the game, and because each 'round' lasts at best a few minutes (if you actually can last that long, you're good), the chances of improving your score is rather decent. http://www.foddy.net/Ninjas.html

Go play Dead Frontier https://www.deadfrontier.com/ It's a game about zombies, fat zombies, fast zombies and burning fast zombies. There is no download, it's played in your browser. Apparently there's a Dead Frontier 2 as well, but Ai-chan hasn't played that yet.
