Re: Pinnacle Entertainment, Inc. Registration Statement on Form S-4

Ladies and Gentlemen:

We have acted as special counsel to Casino Magic, LLC, a Minnesota limited liability company, in connection with the filing by Pinnacle Entertainment, Inc. (the “Company”) with the Securities and Exchange Commission (the “Commission”) of a registration statement on Form S-4 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the proposed issuance by Pinnacle of $850 million aggregate principal amount of its new 6.375% Senior Notes due 2021 (the “New Notes”), in connection with the proposed exchange of $1,000 principal amount of the New Notes for each $1,000 principal amount of its outstanding 6.375% Senior Notes due 2021 (the “Old Notes” and, collectively with the New Notes, the “Notes”) under the Indenture dated as of August 5, 2013 between PNK Finance Corp. and the Bank of New York Mellon Trust Company, N.A., a national banking association, as trustee (the “Trustee”), as supplemented by that Supplemental Indenture dated as of August 13, 2013 by and among the Company, the subsidiary guarantors named therein, and the Trustee (such Indenture, as supplemented, the “Indenture”).

The New Notes will be guaranteed (the “New Guarantees”) by the Guarantors (as defined in the Indenture), including Casino Magic, LLC (the “Minnesota Guarantor”). The New Notes, upon issuance, will be, and the New Guarantees are, governed by the Indenture. This opinion letter is delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In connection with this opinion, we have examined the Registration Statement and the Prospectus, the forms of the Indenture and Notes (including the New Guarantees) and the Notation of Guaranty to evidence the New Guarantees (the “Notation of Guaranty”), and such other corporate proceedings, documents and matters, each as amended to date, of the Minnesota Guarantor, and such other corporate proceedings, documents and matters as we have deemed necessary or appropriate as a basis for this opinion.
