Yes. When you sign in, you get a compliment cards pack and some tokens to purchase stuff from the shop without spending cash. There are premium goods that can be paid with cash though.

Our token is a virtual currency (non cryptocurrency related) called "SP" or "Silver Piece". You earn SPs by playing, and you can use them to purchase more card packs from the shop.

You can also get premium stuff by paying with cash: some items in the shop are listed for paying with PayPal or Cryptocurrencies.
