Polygons

Simple Polygons
Polygons are objects that you CAN kill inside Diep.io.

The main polygons are yellow squares (and often red triangles as well) they are weak and recomended for level 1 players if they would like to level up (and who doesn't want to level up?) the other kind of polygons are pentagons, which are much stronger and are better off to be attacked by tanks with tank builds high reload speed, and better damage.

Green Polygons (Strongest Polygons)
Green polygons are polygons with ten to a hundred times their normal HP. They give a lot of points, but are VERY hard to kill.
