How does the site “recognize” the browser?

There is a browser game in which the admin can ban the user, and the ban works interestingly, here are the initial ones: -
I log in under an anonymous session in chrome, for the first time I get a ban by ip + something else (by ip - it is instant, it works as soon as you enter)
- I change ip, cookies (no difference), I log in under an anonymous session in chrome (no difference) with a different user-agent (no difference), there the ban already works after 10-20 seconds, and blacklists ip
- I change ip, I go through another browser, for example, mozilla - the ban does not work.
The technical side of the issue is very interesting, how does the site recognize me, something like evercookie?
