Pocket Tanks is an artillery game for Android devices. The premise of the game is deceptively simple. Use your artillery tank to destroy all the other tanks and other obstacles on each map. In practice, the game is far more difficult and nuanced. Figuring out the arc trajectory you need to reach your target is a test of your understanding of physics, and once you start to add in all the other factors, the possibilities can become devilishly complex.

The free version includes 40 weapons, and what bot you and your opponents decide to take with your loadout into battle can have a huge impact on the strategy. Whether you're looking to lay down a blanket of napalm or take down your opponent with a flurry of traditional bullets, you're likely to find a strategy that matches your preferences.

Upgrading brings a whole new range of features that add further wrinkles to the gameplay experience. It offers 100 additional weapons. Meanwhile, the digger and the jet booster upgrades vastly improve the role maneuverability options by letting you go underground or into the sky. Pocket Tanks offers online play, and the short session times make it a great option for wiling away a few spare minutes with friends or family.
