1. Enter a nickname and pick a mode (FFA, Team DM, Domination, Tag, Maze, 2TDM, 4TDM), then press Enter to spawn.
2. Move your tank with WASD or arrow keys. Aim the cannon with the mouse — it always tracks the cursor.
3. Left-click or press Space to shoot. Press E to toggle auto-fire; press C to toggle auto-spin.
4. Destroy shapes (squares, triangles, pentagons) and enemy tanks to earn XP. Spend level-up points on Health, Body Damage, Bullet Speed/Damage/Penetration, Reload, Movement Speed.
5. At levels 15/30/45 pick tank class upgrades (Twin, Flank Guard, Machine Gun, Sniper, etc.). For drone tanks, left-click attracts drones and right-click/Shift repels them.
6. Watch the minimap and leaderboard; avoid Boss polygons early. After death, respawn and rematch quickly.

Goal: Level up your tank, evolve through class upgrades, and dominate the arena leaderboard.

Controls above are specific to Diep.io — check in-game prompts if a mode remaps keys.
