Interesting case.

The real question for me is: Why does a Casino use card patterns that are not symmetrical?

Considering how much resource is invested to make sure everything else is as precise as possible, this seems suspicious / unusual.

They're supposed to be symmetrical, but I guess some part of the printing process/card design/some odd combination of the two made them almost imperceptibly asymmetric.

It was just a manufacturing defect that the house didn't know about. Of course its unusual, and the defects were only 1/32 of an inch so its amazing a human can spot that.
