In Diep.io, the main objective for the player is to earn points by destroying different polygon objects and killing other players by firing bullets with their tank. By earning points, the tank levels up. Levelling up allows the player to invest a skill point into tank characteristics such as movement speed and bullet damage, allowing players to get an advantage over other players. Players can also upgrade their tank to more powerful classes every 15 levels up until level 45, giving them abilities other tanks may not have.  Diep.io also has several different game modes featuring team mechanics.
- FFA - free-for-all map with basic player vs player gameplay.
- Survival - battle-royale where the last player standing wins (minimum of 5 players).
- 2 Teams - players fight together against an opposing team to dominate the leaderboard.
- 4 Teams - similar to 2 Teams, but featuring 4 teams, one in each corner of the map.
- Domination - team vs team, your team must take control of all 4 "dominators" to win.
- Tag - 4 teams attempt to dominate - killing an enemy forces them to join your team.
- Maze - FFA, but with large gray walls scattered about to make the likes of a maze.
- Sandbox - A small sandbox map, giving the player access to cheats and all tanks.
Diep.io is often praised for its diverse gameplay through its different game modes and tank upgrades.
