The slot guide originally listed just two plastic card issues from the Big Dog's Bar & Grill in Las Vegas but a previously unlisted card was just found.

The original first issue had "same great benefits" on the last line of the reverse and is similar to the 2nd issue from the Big Dog's Café & Casino.

The new found Big Dog's Bar & Grill card has "locations to enjoy the same great benefits" on last line of the reverse and is similar to the 1st issue from the Big Dog's Café & Casino.

So the new found card is being added as the 1st issue from the Big Dog's Bar & Grill with the original 1st and 2nd issues being renumbered to be consistent with the cards listed for Big Dog's Café & Casino.
