It appears that the slot cards from JACK Entertainment have been produced in at least 2 different issues that may have gone unnoticed.

It looks like the first set of cards had a metallic finish on the front and the 3rd line of text on the reverse started with "may be cancelled..."

While the second set of cards have a plain non-metallic finish on the front and the 3rd line of text on the reverse starts with "be cancelled..."

So far the red J and green A cards have been reported in the 1st set and the red J, green A and blue C have been reported in the 2nd set.

If anyone comes across any levels we don't have listed in either set, or you come across something different pleast let me know so the guides can be updated. There have not been any scans submitted yet for the purple K cards.

Here's samples of the two backs...
