diep.io is a game similar to Slither.io and Agar.io, but instead of cells or snakes you control tanks. And what can you do with a tank that you can't with a snake? Exactly, shoot. And that's precisely what you have to do in this game: shoot at the other tanks nonstop.
At the beginning of a round in diep.io you take control of a small, slow tank that doesn't cause a lot of damage. However, as you destroy polygons (an easy way to gain experience) or tanks controlled by other players, you'll get experience and level up. As you do you can improve your tank's attributes and even add more cannons.
As usual, the stronger your tank is the easier it'll be to destroy the weaker players' tanks. But at the same time you'll become a much juicier and more tempting target, so keep your guard up. Regardless of whether your tank has a low or a really high level you'll encounter new difficulties according to your level.
diep.io is a fun online game that, despite not having the most brilliant graphics, still offers a very addictive gaming experience. Keep in mind, though, that to play you need a stable Internet connection.
