One of such games is World of Tanks, where players divided into two teams use their tanks to win the battle. World of Tanks offers players many different tanks that can be either bought by two type in-game currencies. The silver coins are usually earned after the battle and are used to buy tanks from the tech tree. Premium currency – gold coins – can be used to obtain premium tanks that provide many benefits to the players.
