Currency

There are two types of Currency used in SkyChamp, Gold and Gems (also commonly known as premium currency). As of the 2.1.0 update, Medals are also a form of currency.

Gold
Gold is the main currency of the game, used to buy most items from the shop and level up Okimons, skills or equipment.

Since many of these things require a high amount of gold, gold farming is a common factor in the game. Hatching eggs, exploring, battling and spinning the Lucky Wheel are just a few of the many ways to obtain gold.

Gems
Gems are the secondary, or 'premium', currency of the game.

They can be used to buy rare items from the shop, speed up exploring time, or revive your Okimon once during a flight. Unlike most games, gems are actually fairly easy to obtain and aren't exclusive to paying gamers. They can still be obtained by paying real money, however. Other ways to receive gems include hatching eggs, exploring, and spinning the Lucky Wheel.

Medals
Medals are a championship-exclusive currency.

They are can be used to buy Pettomon Shards or gold from the shop. They can be earned as prizes in League. Getting in the top ten of your league or participating in the Global championship will give you medals.
