The economy in Tanki Online features a wide variety of in-game currencies and resources which you can use to purchase in-game items or receive rewards. Some currencies are obtainable for free by completing missions & challenges in the game while others are shop exclusive, which means you'll have to pay real money in order to get your hands on them.
Containers are items that have unknown contents inside them. Upon opening the box, players can receive something from a selection of items. The contents will vary all the way from supplies to rare paints and more.
With a Premium Account, users will be getting a whole list of advantages such as 50% more experience points, 100% more crystals in every battle, double the amount of Stars per battle, daily bonuses obtained every day you log in after the server restart, a special and unique paint during the time in which the Premium Account will be active, the ability to buy certain Paints, a special rank icon with the ability of turning it ON / OFF and a PRO Battles Pass.
Crystals are the game's unit of currency. Currently, crystals are used to buy and upgrade hulls, weapons, most paints, supplies, and passes, with the occasional surprise item, often associated with holidays or special days in the game. There are several ways to get crystals.
Stars are mainly a form of points to complete monthly challenges. They can be obtained from matchmaking battles only, but they are also available for purchase from the shop. Stars are used as resources for the war to determine a faction's victory.
Tankoins are the game's secondary currency and are primarily used to purchase items within the Shop. They are a bridge between real money and in-game content. Tankoins can be purchased from the Shop, but can also be obtained via coinboxes, containers, challenges, and special missions.
