For example, I clicked random page a bunch of times until I found two unrelated pages on topics I was familiar with. Specifically, Touchdown Celebration and Americans in Japan. I started from Americans in Japan, clicked on 'United States,' then 'American Football,' then 'touchdown,' then 'touchdown celebration' in the see also section. In this case, I earned a score of 4.
It is quite possible to get a different score depending on how efficiently you choose links within each article. I think a score of four is unusually low for this game, and that's probably because the two random articles I chose were actually kind of similar. Here's a more challenging one:

to
https://en.wikipedia.org/wiki/Tippe_top
What score will you get?
