Currencies (SF1)

Shadow Fight 1 features two primary types of currencies. They are gold coins and rubies, of which the latter is the premium currency of the game.

Gold
There are several ways to earn Gold, also known as Coins, in the game:
 * Finishing battles - If players win the battle, they earn gold.
 * Playing Try Your Luck! - After fighting the first wave of enemies, players will earn 5 gold each time they beat the next row of henchmen.
 * Completing the Tower Of Death every week - Each time the player's record of defeated opponents is beaten, they will earn gold (5 for another round, 10 for 2 more rounds and so on).
 * Making an in-app purchase.
 * Completing a collection.

It is primarily used to buy items from Shop or for participating in Tournaments.

Rubies
Although much more difficult to obtain that Coins, there are still several methods players can use to obtain Rubies:
 * Completing daily objectives - If the player completes all three objectives of the day, they will earn 1 ruby.
 * Players can choose to buy rubies using real-life currency.
 * Players can earn rubies for free by inviting a friend to play the game. The friend has to reach level 7 in order for the player to earn 15 rubies.
 * Players can go to the Shadow Arena and play under Master Sigil. Getting into one of the top positions will earn the player rubies.

Rubies can be spent in various ways. At the Shop, players can use rubies to buy the following items:
 * 1) Advanced Weapons.
 * 2) Items, such as energy potions, scrolls and jars of Ki.
 * 3) Players can use it to buy seals.
 * 4) Change location of the player's dojo.
 * 5) Change silhouette.

They can use it in the Try Your Luck! section to:
 * 1) Replay the game.
 * 2) Add more lives(hearts) to that session (temporary).

At the Dan Test, if the players do not have enough friends but still wish to participate, they can do so by paying rubies.

Players can also spend rubies at the Shadow Arena to participate in the Master Sigil section.

Trivia

 * Both gold and rubies have a counterpart in other Shadow Fight games. They are known as Coins and Gems respectively.
