Caveballs

There are 2 ways cueballs (sometimes called poolballs or caveball) can be interpreted and used. The first method is the one covered by the /r/polandball staff, which must be applied inside the subreddit. The alternative usage is also seen outside of /r/polandball.

Usage on /r/polandball
On their About page, the /r/polandball mods have already explained the usage of these kinds of balls. The rules on using them state:

"Cueballs can be used for people or tribes that aren't or weren't organised as a nation in a modern sense. For example in historic comics where European explorers encountered indigenious people. The cueball colors describe the respective skin colors. Actually only the black and the brown one are used and sometimes the green ball for aliens."

- /r/polandball mods

They are inspired by real life cueballs. Officially they are never designated as "caveballs". Only 8-balls, 7-balls, 6-balls and 1-balls are allowed. The reason these cueballs are used is because their colours represent the skin colour of the actual people/aliens. (which is why the other balls aren't used, unless you've seen some kind of purple or blue people)This, however, is only true for /r/polandball, and other variants have appeared outside of the subreddit as well.
