There are two types of currency available for purchase in the game: banknotes and/or pearls.

NOTE: You can buy banknotes and pearls ONLY through the Let’s Fish game!
In order to make a purchase, click the Payments tab at the top of the window.
Select a payment provider and a pack of banknotes or pearls you want to purchase. Then, select your payment method. Follow the instructions to complete the payment.
The purchased currency should appear on your profile in the game. In some cases, it might take a while.
If you bought banknotes or pearls via Facebook or other social networking sites and you have not received them, try refreshing the page. If the currency has not been added to your account, please contact the support team of a given website as they are the ones responsible for in-game payments.
