In order to receive your NFT game cards, you will need to manually claim them. They will be waiting until you do.
To manually claim the NFTs on bloks.io, please follow these steps:
1) Go to wax.bloks.io and login at the top right
3) Please go to the account "m.federation" on wax.bloks.io
4) Go to "Contract", "Actions" and then to "claimnfts"
5) Enter your account name into the field "miner", then click the button "Submit Transactions" and sign it with your WAX Cloud Wallet.
6) Next, a message like this (below) will appear.
Note: A successful claim action does not mean that you will always get an NFT game card automatically in the future; it means you will be claiming any currently available due to earning them through past mining.
