There is now a newer version of the hard rock slot cards that look like packing crates that are listed as the 9th issue.

The original cards have the website in the lower left corner on the reverse

The newer cards now have the website right under the casino's name, higher up on the card. These are being added as the 10th issue in the slot card guide.
