Despite being one of the older titles, this is still easily one of the best .io games. Players join the game as a tank, and destroying objects or other players earns points which can then be used to upgrade the tank throughout the round. Tanks also level up, allowing players to choose different body types and allowing for a wide variety of vehicles. This includes double-barreled blasters, machine guns, triple barrels, a sniper model, and much more.

As if that weren't enough, Diep.io features a suite of new modes for players to dive into/ Don’t feel like going solo? There’s a 50 v. 50 option. Feel like playing in a team environment? There’s a team mode, where red and blue face off to claim the three out of four turrets. Have a thirst for power? Go for Mothership mode.
