What are the Currencies?

Gold

Gold is the 'hard currency' of the game and it enables you to buy more slots in your garage if you want to have more than 5 tanks at once. Gold is also used to purchase premium accounts which are essentially experience doublers, and a small number of 'premium tanks' which offer a bonus to how much credit they generate. Gold can also be used to buy premium ammo for your tanks, these shells grant a slight bonus to armour penetration and damage.

Experience

At the end of each round the tank you use will earn experience based on your performance in battle. You can also earn general (free) experience by battling any tank. The experience you earn can be used to upgrade tank modules and tanks. It is also possible to buy experience by converting credits into experience.

Credits

As with experience you can only earn credits playing the game, they cannot be purchased directly using real money. Credits (sometimes referred to as silver) can however be bought with gold coins which you can then use at the store. To browse for offers and packages at the store just tap the store icon on the top left of the screen.

Premium Accounts

If you subscribe to the premium account you will earn 50% more credit and experience per battle which will enable you to get better tanks and equipment faster. There is the possibility of a special offer such as a 30-day premium account for only $1.99 (instead of $7.99) presenting itself after a battle which if it does you will have only one chance to buy it. Alternatively you can get a premium account at a discount by purchasing iTunes gift cards.
