Just curious, but if a prypto code is already redeemed does the wallet just say "error redeeming Prypto card"?
you seem to have a PC where an additional file is required ...
I think you will need this file:
https://slproweb.com/download/Win32OpenSSL_Light-1_0_2g.exe ( you can know more here:
https://slproweb.com/products/Win32OpenSSL.html )
After, Reboot your Casinocoin or Sandcoin wallet.
Check again a prypto card code or QR code.
if prypto code is already redeemed, you will see message "Prypto Card already redeemed or invalid."
i hope this help you
Prypto card redemption works fine with me. I have tested into both CSC and Sandcoins wallet and it works like a charm. All I get is a message saying: "Prypto card already redeemed..."
Speaking of which, I am anxious to know when will Prypto release its cards for the public, as I would like to own some myself and promote CSC to my friends with them. I like the idea of scratching the card and claiming your CSC price. It makes anybody to become more interested in cryptos themselves.

My understanding is that they printed two batches initially with 10 CSC each. Half went to the Bahamas casinos and the other half prypto is selling through their website and through their resellers. If you contact a reseller they can probably start ordering some cards for you.
Later I believe there will be more denominations and some partners/casinos already want to get custom branded casinocoin cards to support their affiliate marketing programs. Affiliate marketing program cards would be distributed at expos and through mailings to customers.
I don't know all the details, dates, etc, but last time I chatted with GC he seemed to have made some significant progress with his partners getting closer to launch.
