Item 6. Indemnification of Directors and Officers.

        The Nevada Revised Statutes provide that a corporation may indemnify its officers and directors against expenses actually and reasonably incurred in the event an officer or director is made a party or threatened to be made a party to an action (other than an action brought by or on behalf of the corporation as discussed below) by reason of his or her official position with the corporation provided the director or officer (1) is not liable for the breach of any fiduciary duties as a director or officer involving intentional misconduct, fraud or a knowing violation of the law or (2) acted in good faith and in a manner he or she reasonably believed to be in the best interests of the corporation and, with respect to any criminal actions, had no reasonable cause to believe his or her conduct was unlawful. A corporation may indemnify its officers and directors against expenses, including amounts paid in settlement, actually and reasonably incurred in the event an officer or director is made a party or threatened to be made a party to an action by or on behalf of the corporation by reason of his or her official position with the corporation provided the director or officer (1) is not liable for the breach of any fiduciary duties as a director or officer involving intentional misconduct, fraud or a knowing violation of the laws or (2) acted in good faith and in a manner he or she reasonably believed to be in the best interests of the corporation. The Nevada Revised Statutes further provide that a corporation generally may not indemnify an officer or director if it is determined by a court that such officer or director is liable to the corporation or responsible for any amounts paid to the corporation as a settlement, unless a court also determines that the officer or director is entitled to indemnification in light of all of the relevant facts and circumstances. The Nevada Revised Statutes require a corporation to indemnify an officer or director to the extent he or she is successful on the merits or otherwise successfully defends the action.

        The Registrant's bylaws provide that it will indemnify its directors and officers to the maximum extent permitted by Nevada law, including in circumstances in which indemnification is otherwise discretionary under Nevada law. In addition, the Registrant intends to enter into separate indemnification agreements, the form of which is attached as Exhibit 10.15 to the Registrant's Amendment No. 3 to Registration Statement on Form S-1 (Reg. No. 333-90600), with its directors and officers which would require the Registrant, among other things, to indemnify them against certain liabilities which may arise by reason of their status or service other than liabilities arising from willful misconduct of a culpable nature. The Registrant also intends to maintain director and officer liability insurance, if available on reasonable terms. These indemnification provisions and the indemnification agreements may be sufficiently broad to permit indemnification of the Registrant's officers and directors for liabilities, including reimbursement of expenses incurred, arising under the Securities Act. The Registrant has been advised that, in the opinion of the Commission, indemnification of directors or officers for liabilities arising under the Securities Act is against public policy and, therefore, such indemnification provisions may be unenforceable.

Subject to all of the other terms and conditions of this Agreement, following the death of Optionee, this Option may, to the extent it is vested and exercisable by Optionee in accordance with its terms on the date of death, be exercised by Optionee's beneficiary or other person entitled to exercise this Option in the event of Optionee's death under the Plan.

Exhibit 5.1

October 28, 2002

Wynn Resorts, Limited
3145 Las Vegas Boulevard South
Las Vegas, Nevada 89109

Ladies and Gentlemen:

        We have acted as special Nevada counsel to Wynn Resorts, Limited, a Nevada corporation (the "Company"), in connection with the filing of a Registration Statement on Form S-8 (the "Registration Statement") with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act"), covering the registration of up to Nine Million Seven Hundred Fifty Thousand (9,750,000) shares (the "Shares") of the Company's common stock, par value $.01 per share, issuable upon the exercise of options granted pursuant to the Company's 2002 Stock Incentive Plan (the "Plan").

        In rendering the opinions hereinafter expressed, we have examined the Registration Statement, the Plan, the Company's Articles of Incorporation and Bylaws, each as amended to date, and such other documents, records, certificates, memoranda and other instruments as we have deemed necessary as a basis for this opinion. We have also obtained from officers and agents of the Company and from public officials, and have relied upon, such certificates, representations and assurances as we have deemed necessary and appropriate for purposes of this opinion.

        Without limiting the generality of the foregoing, in our examination, we have assumed without independent verification, that (i) each document we reviewed has been duly and validly executed and delivered by each party thereto to the extent due execution and delivery are a prerequisite to the effectiveness thereof, (ii) each natural person executing a document has sufficient legal capacity to do so, (iii) all documents submitted to us as originals are authentic, the signatures on all documents that we examined are genuine, and all documents submitted to us as certified, conformed, photostatic or facsimile copies conform to the original document, and (iv) all corporate records made available to us by the Company and all public records reviewed are accurate and complete.

        We are qualified to practice law in the State of Nevada. The opinions set forth herein are expressly limited to the effect of the general corporate laws of the State of Nevada as in effect as of the date hereof and we do not purport to be experts on, or to express any opinion herein concerning, or to assume any responsibility as to the applicability to or the effect on any of the matters covered herein of, any other laws, including any federal securities law, or any state securities or "blue sky" laws or regulations.

        On the basis of the foregoing, and in reliance thereon, and having regard to legal considerations and other information that we deem relevant, we are of the opinion that the Shares, when and to the extent issued and sold in accordance with the Registration Statement and the Plan, will be validly issued, fully paid and non-assessable (except for any Shares issued pursuant to certain deferred payment arrangements, which will be fully paid when such deferred payments are made in full).

        You may rely upon this opinion in connection with the filing of the Registration Statement. This opinion may not be relied upon by any other person, or used by you for any other purposes, without our prior written consent in each instance.



        We consent to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission promulgated thereunder.

    Very truly yours,
