This is a clever way to recruit hackers into the Google Security team. Here's some of the most useful content from the webpage:

is the goal to hack the chess game or the admin panel? I never know how to do these things

Well, I got the admin panel to show a completely blank page, instead of an Invalid Login message, so that's progress.

You got it to 500, which can be seen via the network dev tools console. (A place you can also right click and "Copy as cURL", to iterate on the command line faster) ^^

A 500 is almost always a good sign when it comes to hacking. Hacking is the art of finding the difference between intended behavior and actual behavior. That is pretty much the definition of a 500.

Well I got the admin menu to show up. Still lost the chess game though (my chess skills need work).

A little bit of python and some stockfish could probably improve your play dramatically!
