- This Category is for Polygons in the original Diep.io. For Polygons in Arras.io, see Category:Arras Polygons.
- Note: Drones and Protectors are not included in this list, and are listed under ammunition.
Polygons in Diep.io are the floating shapes that players destroy to gain points. Destroying polygons is a way for players to gain levels and improve stats without risking their tank against another player. Polygons cannot be controlled, but may drift around, apparently randomly, on the grid. The exceptions are Alpha Pentagons, which only spawn in the Pentagon Nest.
- If a player died from a Polygon in earlier versions of the game, the Death Screen would say: “You were killed by an unnamed Tank”.
- In the very early days of Diep.io, polygons didn’t exist, forcing players to immediately start fighting others at level 1, making the game practically impossible.
