An unpublished case is where:
An unreported case is where:

Unreported cases, which have not been certified for publication, are not considered a binding authority, but they can be used as persuasive authority.
Some courts only allow citations to published cases. Thus, when preparing a document to be submitted to a court, it is good practice to check the applicable court rules to confirm whether unpublished cases can be cited to in the filings of that court.
Effective January 1, 2021, in Illinois, an amendment to Supreme Court 23 allows for unpublished decisions to be cited to for persuasive purposes.
Elements of a Unpublished or Unreported Case Citation:
If a pinpoint citation is included, page numbers should be identified with an asterisk (*), and paragraph number should be identified with a paragraph symbol (¶).

Black Law's Dictionary defines 'slip opinion' as a preliminary draft of a court opinion not yet ready for publication. Unlike unreported opinions, a slip opinion can be cited as authority. Think of a slip opinion as the decision before the reported decision. Most of the time slip opinions do not change in the substance, but they could need to fix citations or formatting.
According to Rule 10.8.1(b), when a case is unreported but available in a separately printed slip opinion, the citation is the same as an unreported case, except the database indicator is omitted.
