Who knows a site where you can just stick without downloading?

I don't want to install anything, fill out forms or download apps. I just want to go in and play in the browser.

I have a problem with it - I sit on https://au-betonred.com/, there everything works in the browser without installation. No fuss: open, spin, close. Even on the phone goes without lags. It does not strain and does not load the system - just what you described.
