EXHIBIT 10.9(G)

                 NON-NEGOTIABLE PROMISSORY NOTE


     1.    Promise  to Pay.  For good and valuable consideration,
AMERISTAR  CASINOS,  INC.,  a  Nevada  corporation  ("Borrower"),
promises   to  pay  to  DOMINIC  J.  MAGLIARDITI,  an  individual
("Lender"),  $179,080  with  interest  on  the  unpaid  principal
balance  at eight percent (8%) per annum simple interest (subject
to  Paragraph  2) (the "Interest Rate") from June 1,  1997  until
paid  in  accordance with the terms contained  herein.   Interest
shall  be computed on the basis of a 365-day year and the  actual
number of days elapsed.  Should any accrued interest not be  paid
on any Interest Payment Date, it shall thereafter accrue interest
as  principal.   All payments shall be made by wire  to  Lender's
account  at  Wells Fargo Bank, N.A., ABA Routing No.:  122402049,
Account No.: 0834-944134, or at such other place as the holder of
this Note may from time to time designate.  All payments shall be
applied  first  to  accrued interest and then  to  the  principal
balance.

     2.   Payment Schedule.  This Note may be prepaid in whole or
in part at any time without penalty.  Borrower shall pay interest
accruing  under this Note as follows: (a) interest accruing  from
the  date  hereof  through July 20, 1997 shall be  paid  (to  the
extent  not  previously  paid) on July  20,  1997;  (b)  interest
accruing  from  and after July 21, 1997 shall  be  paid  (to  the
extent  not previously paid) on the twentieth (20th) day of  each

1998;  and (c) interest accruing from and after October 21,  1998
shall  be  paid  (to  the  extent not  previously  paid)  on  the
twentieth (20th) day of each calendar month thereafter until  the
date (the "Payment Termination Date") that is the earlier of  the
Maturity Date or the date when the principal amount of,  and  all
accrued interest on, this Note has been paid in full.  Each  date
upon  which  a  payment is required to be made  pursuant  to  the
foregoing  provisions  of this Section 2  shall  be  referred  to
herein  as  a  "Payment Date."  In addition, Borrower  shall  pay
installments of  principal as follows:

Lender as an installment of principal; and

      (2)   On  July  20, 2004, Borrower shall pay $17,908.02  to
Lender as an installment of principal.

     If  on any Payment Date before the Payment Termination Date,
Borrower  fails to make any payment of interest or  principal  to
Lender,  as  required  above, and Borrower  fails  to  cure  such
failure  within ten (10) days after receiving written  notice  of
such failure from Lender, then, commencing as of the next Payment
Date, the Interest Rate hereunder shall be increased as follows:

         (i)   With  respect  to  the first  such  increase,  the
     Interest  Rate shall be increased so that the Interest  Rate
     shall  thereafter  equal  eleven  and  four  tenths  percent
     (11.4%) per annum simple interest;

          (ii)  With  respect  to the second such  increase,  the
     Interest  Rate shall be increased so that the Interest  Rate
     shall  thereafter  equal fourteen and  seven-tenths  percent
     (14.7%) per annum simple interest;  and

          (iii)     With respect to the third such increase,  the
     Interest  Rate shall be increased so that the Interest  Rate
     shall  thereafter  equal eighteen percent  (18%)  per  annum
     simple  interest.  The Interest Rate shall not be  increased
     to  a  level greater than eighteen percent (18%)  per  annum
     simple interest.

     3.    Maturity.   All  unpaid  principal  and  accrued,  but
unpaid,  interest shall be due and payable on December  31,  2004
(the "Maturity Date").

     4.   Subordination.

          4.1    Note   Subordinated  to   Senior   Indebtedness.
Anything herein to the contrary notwithstanding, each of Borrower
and  Lender  agrees  that  the payment of  the  Obligations  with
respect  to this Note is subordinated, to the extent and  in  the
manner provided in this Paragraph 4, to the prior payment in full
in  cash  of  all  Senior Indebtedness.  The provisions  of  this
Paragraph  4  are made for the benefit of the holders  of  Senior
Indebtedness and holders of Senior Indebtedness may  enforce  the
provisions  of  this Paragraph 4 without any need to  demonstrate
any reliance hereon.

          4.2   No  Payment  on  Note  in Certain  Circumstances.
Unless  Subparagraph 4.3 shall be applicable, upon  (i)  (A)  the
occurrence  of any default in the payment of all or  any  portion
then  due of  principal of, premium, if any, or interest  on  any
Senior  Indebtedness,  (B)  the occurrence  of  any  event  which
entitles one or more persons to act to accelerate the maturity of
any  Senior  Indebtedness or (C) the existence of  any  facts  or
circumstances which would result in the occurrence of  any  event
described  in clause (A) or clause (B) if Borrower were  to  make
any  payment  hereunder (any event described  in  clause  (A)  or
clause  (B) or facts or circumstances described in clause (C),  a
"Senior  Indebtedness Default") and (ii) receipt  by  the  Lender
from   the   indenture  trustee  or  other  trustee,   agent   or
representative for any Senior Indebtedness (the "Representative")
of  written notice of such Senior Indebtedness Default,  then  no
direct  or  indirect payments or distribution of  any  assets  of
Borrower  of any kind or character shall be made by or on  behalf
of  Borrower  on account of the Obligations on this  Note  or  on
account  of  the  purchase or redemption or other acquisition  of
this  Note  whether pursuant to the terms of this  Note  or  upon
acceleration   or   otherwise  unless  and  until   such   Senior
Indebtedness  Default shall have been cured or  waived  or  shall
have  ceased  to exist, or such Senior Indebtedness as  to  which
such   Senior  Indebtedness  Default  relates  shall  have   been
discharged  or  paid in full in cash, after which Borrower  shall
resume  making any and all required payments in respect  of  this
Note,   including  any  missed  payments.   In  the  event  that,
notwithstanding the foregoing, the Lender or any holder  of  this
Note  shall  have received any payment or distribution prohibited
by  the foregoing provisions of this Subparagraph 4.2, then  such
payment or distribution shall be received, segregated from  other
funds,  and held in trust by Lender or such other holder of  this

immediately  be  paid  over  and  delivered  forthwith   to   the
Representatives  or  as a court of competent  jurisdiction  shall
direct.

          4.3   Note Subordinated to Prior Payment of All  Senior
Indebtedness  on  Dissolution, Liquidation or  Reorganization  of
Borrower.  Upon any payment or distribution of assets of Borrower
of   any  kind  or  character,  whether  in  cash,  property   or
securities,  upon any dissolution, winding-up, total  or  partial
liquidation  or  total  or  partial  reorganization  of  Borrower
(including,  without  limitation, in  bankruptcy,  insolvency  or
receivership proceedings or upon any assignment for  the  benefit
of creditors or any other marshaling of assets and liabilities of
Borrower and whether voluntary or involuntary):

          (a)  the holders of all Senior Indebtedness shall first
be  entitled  to receive payments in full in cash of all  amounts
payable  under Senior Indebtedness before Lender is  entitled  to
receive  any  payment with respect to this  Note  and  until  all
Obligations with respect to the Senior Indebtedness are  paid  in
full  in  cash,  any distribution to which Lender  or  any  other
holder  of  this  Note would be entitled shall  be  made  to  the
holders of Senior Indebtedness;

          (b)   any payment or distribution of assets of Borrower
of   any  kind  or  character,  whether  in  cash,  property   or
securities,  to  which Lender shall be paid  by  the  liquidating
trustee  or  agent  or  other person making  such  a  payment  or
distribution,  directly to the holders of Senior Indebtedness  or
their  Representative  until  all Senior  Indebtedness  remaining
unpaid  shall have been paid in full in cash, after giving effect
to  any concurrent payment or distribution to the holders of such
Senior Indebtedness; and

          (c)   in the event that, notwithstanding the foregoing,
any  payment or distribution of assets or securities of  Borrower
of   any  kind  or  character,  whether  in  cash,  property   or
securities,  shall be received by Lender or any other  holder  of
this  Note  on  account  of principal of,  premium,  if  any,  or
interest on this Note before all Senior Indebtedness is  paid  in
full  in  cash, such payment or distribution shall  be  received,
segregated from other funds, and held in trust by Lender or  such
other  holder of this Note, as the case may be, for  the  benefit
of,  and shall immediately be paid over to, the holders of Senior
Indebtedness  or their Representative, ratably according  to  the
respective amounts of Senior Indebtedness held or represented  by
each,  until all Senior Indebtedness remaining unpaid shall  have
been  paid  in full in cash after giving effect to any concurrent
payment  or  distribution  to  or  for  the  holders  of   Senior
Indebtedness.

          4.4   Lender  to Be Subrogated to Rights of Holders  of
Senior  Indebtedness.  Subject to the payment in full in cash  of
all Senior Indebtedness, Lender shall be subrogated to the rights

          6.    Miscellaneous Provisions.  No provision  of  this
Note  may  be  amended, modified, supplemented, changed,  waived,

affected  or  impaired thereby.  In the event  of  a  failure  by
Borrower  prior  to  the Maturity Date to  pay  any  amounts  due

(b)  that  its  rights hereunder are subject  to  the  provisions
hereof.  This Note is not negotiable.

          7.    Novation and Pari Passu Provisions.   This  Note,
together with another Non-Negotiable Promissory Note of even date
herewith of Borrower in favor of Lender in the original principal
amount  of  $280,100  (collectively,  the  "Magliarditi  Notes"),
constitute  a novation of that certain Non-Negotiable  Promissory
Note  dated  as of June 1, 1997 in the original principal  amount
$459,180  made  by  Borrower in favor of  Lender  (the  "Original
Note").   The  Magliarditi Notes are and shall be subordinate  to
Senior Indebtedness to the same extent as the Original Note,  and
any  and all statements in any Senior Indebtedness providing  for
the   subordination  of  the  Original  Note   to   such   Senior
Indebtedness shall remain effective for, and applicable  to,  the
subordination  of  the Magliarditi Notes.  Without  limiting  the
foregoing, (i) each of the Magliarditi Notes is and constitutes a
"Gem  Settlement  Note" as defined in and for  purposes  of  that
certain  Credit Agreement dated as of July 8, 1997,  as  amended,
among Borrower and various of its subsidiaries as borrowers,  the
lenders named therein and Wells Fargo Bank, National Association,
as  Arranger, Agent Bank and Swingline Lender, and (ii)  each  of
the   Magliarditi   Notes   is   and   constitutes   "Refinancing
Indebtedness" of the "Gem Notes" as such terms are defined in and
for purposes of that certain Indenture dated as of July 15, 1997,
as  amended, among First Trust National Association, as  Trustee,
Borrower and various subsidiaries of Borrower as guarantors.  The
novation  of  the  Original Note is not intended  to  affect  the
limitation on the amount of Senior Indebtedness provided  for  in
Subparagraph  4.5  of this Note.  In the event that  Borrower  is
unable  to  make full payment of principal of and/or interest  on
both  the  Magliarditi Notes when due, the total amount  paid  at
such  time by Borrower in respect of the Magliarditi Notes  shall
be  applied  ratably to the payment of the amounts then  due  and
unpaid  on the Magliarditi Notes, without preference or  priority
of  any  kind,  according to the amounts due and payable  on  the
Magliarditi Notes.  By the acceptance of this Note, Lender hereby
agrees  and  consents to such ratable application  on  behalf  of
itself  and  all  subsequent holders of this Note;  however,  any
acceptance  by the holder of this Note of any partial payment  of
any  amount  due  under  this  Note shall  not  be  considered  a
forgiveness  of indebtedness or a waiver of timely payment.   The
respective  original holders of the Magliarditi  Notes  are,  and
subsequent  holders of the Magliarditi Notes may be, entitled  to
certain rights or subject to certain obligations pursuant to  the
terms  of  a Settlement Agreement entered into in September  1999
among Bryan and Dawn Hafen, Steven W. Rebeil, individually and as
Trustee  of the Karizma Trust, Dominic Magliarditi, Gem Mesquite,
Ltd.,  Gem Development Co., Ameristar Casino Las Vegas, Inc.  and
