                             AMERISTAR CASINOS, INC.

                 CODE OF ETHICS FOR THE CHIEF EXECUTIVE OFFICER,

              CHIEF FINANCIAL OFFICER AND CHIEF ACCOUNTING OFFICER

         In my role as Chief Executive Officer ("CEO"), Chief Financial Officer
("CFO") or Chief Accounting Officer of Ameristar Casinos, Inc. (the "Company"),
I agree to adhere to and advocate the following principles and responsibilities
governing professional conduct and ethics:

         1.       Act with honesty and integrity, avoiding actual or apparent
                  conflicts of interest in personal and professional
                  relationships. A "conflict of interest" exists when an
                  individual's private interests interfere or conflict in any
                  way (or even appear to interfere or conflict) with the
                  interests of the Company.

         2.       Provide stockholders and other constituents with information
                  that is accurate, complete, objective, relevant, timely and
                  understandable. If I am the CEO or CFO, I shall review the
                  Company's annual and quarterly reports before certifying and
                  filing them with the Securities and Exchange Commission.

         3.       Comply with all applicable laws, rules and regulations of
                  federal, state and local governments, and other appropriate
                  private and public regulatory agencies.

         4.       Act in good faith, responsibly, with due care, competence and
                  diligence, without misrepresenting material facts or allowing
                  my independent judgment to be subordinated.

         5.       Respect the confidentiality of information acquired in the
                  course of business except when authorized or otherwise legally
                  obligated to disclose the information. I acknowledge that
                  confidential information acquired in the course of business is
                  not to be used for personal advantage.

         6.       Proactively promote ethical behavior among employees of the
                  Company and as a responsible partner with industry peers and
                  associates.

         7.       Maintain control over and responsibly manage all assets and
                  resources employed or entrusted to me by the Company.

         8.       Promptly report illegal or unethical conduct by any director,
                  officer or employee that has occurred, is occurring or may
                  occur, including any violations of this Code of Ethics. Such
                  report shall be made to the Director of Regulatory Compliance
                  and the Chairman of the Audit Committee of the Board of
                  Directors and shall include conduct of a financial or
                  non-financial nature.

         9.       Refrain from directly or indirectly taking any action to
                  improperly influence, coerce or mislead the Company or its
                  independent auditors for the purpose of rendering the
                  financial statements of the Company or its subsidiaries
                  misleading.

         10.      Comply with this Code of Ethics. I understand that if I
                  violate any part of this Code of Ethics, I will be subject to
                  disciplinary action, up to and including termination of
                  employment.

         I understand that if I believe there is a conflict between this Code of
Ethics and a Company policy or procedure or any applicable law, rule or
regulation, I must consult with the Legal Affairs Department for guidance.

         I understand that there shall be no waiver of or amendment to any part
of this Code of Ethics except by the Board of Directors or a designated Board
committee. In the event that a waiver of or amendment to this Code of Ethics is
granted, the notice of the waiver or amendment shall be posted on the Company's
website within five business days of the Board of Directors' or designated Board
committee's action or shall be disclosed otherwise as required by applicable law
or regulation. Notices posted on the Company's website shall remain posted for a
period of 12 months and shall be retained in the Company's files as required by
law.
