Puffin Coins are the currency used in the Puffin Store. They are not, in any way, connected to real currencies. That would not comply with our policy, which keeps all things related to Puffin Studios outside of real-life currencies, or crypto-currency.
Puffin Coins are connected to your profile. By completing the redeem form, we will update your profile page to the amount of Puffin Coins you own. To do this, go to the redemption form, and input your Puffin Store username and the password to your Puffin Store account. This is to prove you own the account, and the email connected to that submission on the form. Finally, we will get the submission and add the coins you earned to your profile. We will send you an email when we add your coins, and if you go to your profile (sites.google.com/view/puffinstore/<username>/?authuser=0).
After redeeming some Puffin Coins, you will go to the paid app page on our Store, like My Chubby Bunny: Police Rush. Copy the purchase code from that app's page, and go to our Purchase Form. Input the login info to your Puffin Store account, and also input the code from the paid app's page. We will email you when we have deducted the Puffin Coins from your account, and also in that site update, we will update our paying servers to add your account to the owned list. Any time you play the game, it will open a popup asking for you to sign in to Puffin Store.
