         The   undersigned   acknowledges   receipt  of  the  Prospectus   dated
________________,  1999 (the  "Prospectus")  of Riviera  Black Hawk,  Inc.  (the
"Company") and this Letter of Transmittal (the "Letter of  Transmittal"),  which
together  constitute  the  Company's  Offer to Exchange (the  "Exchange  Offer")
$45,000,000  principal  amount  of its 13%  First  Mortgage  Notes due 2005 With
Contingent  Interest (the "New  Notes"),  which have been  registered  under the
Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  pursuant  to a
Registration  Statement  of which  the  Prospectus  is a part,  for each  $1,000
principal  amount  of its  outstanding  13% First  Mortgage  Notes due 2005 With
Contingent  Interest (the  "Existing  Notes"),  of which  $45,000,000  principal
amount is outstanding, upon the terms and conditions set forth in the Prospectus
and this Letter of  Transmittal.  Other  capitalized  terms used but not defined
herein have the meaning given to them in the Prospectus.

         For each  Existing  Note  accepted  for  exchange,  the  holder of such
Existing Note will receive a New Note having a principal amount equal to that of
the  surrendered  Existing Note.  Interest on the New Notes will accrue from the
last  interest  payment date on which  interest  was paid on the Existing  Notes
surrendered  in  exchange  therefor.  Holders of  Existing  Notes  accepted  for
exchange  will be deemed to have waived the right to receive any other  payments
or accrued  interest on the Existing Notes.  The Company  reserves the right, at
any time or from time to time, to extend the Exchange  Offer at its  discretion,
in which event the term "Expiration Date" shall mean the latest time and date to
which the Exchange  Offer is extended.  The Company shall notify  holders of the
Existing  Notes





of any extension by means of a press release or other public  announcement prior
to 9:00 A.M.,  New York City time, on the next business day after the previously
scheduled Expiration Date.

         This  Letter  of   Transmittal  is  to  be  used  by  Holders  if:  (i)
certificates  representing  Existing Notes are to be physically delivered to the
Exchange Agent herewith by Holders;  (ii) tender of Existing Notes is to be made
by book-entry  transfer to the Exchange  Agent's account at The Depository Trust
Company  ("DTC"),  pursuant to the procedures set forth in the Prospectus  under
"The Exchange Offer _ Procedures for Tendering  Existing Notes" by any financial
institution  that is a  participant  in DTC and whose name appears on a security
position  listing as the owner of  Existing  Notes or (iii)  tender of  Existing
Notes is to be made according to the guaranteed delivery procedures set forth in
the  Prospectus  under "The Exchange  Offer - Guaranteed  Delivery  Procedures."
DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

         The term "Holder" with respect to the Exchange  Offer means any person:
(i) in whose name Existing  Notes are  registered on the books of the Company or
any other  person  who has  obtained a  properly  completed  bond power from the
registered  Holder;  or (ii) whose  Existing Notes are held of record by DTC (or
its nominee) who desires to deliver such Existing  Notes by book-entry  transfer
at DTC. The  undersigned  has  completed,  executed and delivered this Letter of
Transmittal to indicate the action the undersigned  desires to take with respect
to the Exchange Offer.

         Holders of Existing Notes that are tendering by book-entry  transfer to
the  Exchange  Agent's  account at DTC can  execute  the tender  through the DTC
Automated  Tender Offer  Program  ("ATOP"),  for which the  transaction  will be
eligible.  DTC participants  that are accepting the Exchange Offer must transmit
their  acceptance  to DTC,  which  will  verify  the  acceptance  and  execute a
book-entry  delivery to the Exchange Agent's DTC account.  DTC will then send an
Agent's Message to the Exchange Agent for its acceptance.  DTC  participants may
also accept the  Exchange  Offer prior to the  Expiration  Date by  submitting a
Notice of Guaranteed  Delivery or Agent's Message  relating thereto as described
herein under Instruction 1, "Guaranteed Delivery Procedures."

         The  instructions  included  with this  Letter of  Transmittal  must be
followed.  Questions and requests for assistance or for additional copies of the
Prospectus,  this Letter of Transmittal or the Notice of Guaranteed Delivery may
be directed to the Exchange Agent. See Instruction 11 herein.

         EXISTING NOTES MUST COMPLETE THIS LETTER OF TRANSMITTAL IN ITS
             ENTIRETY. PLEASE READ THIS ENTIRE LETTER OF TRANSMITTAL

Ladies and Gentlemen:

         Subject  to the  terms  and  conditions  of  the  Exchange  Offer,  the
undersigned hereby tenders to the Company the principal amount of Existing Notes
indicated  above.  Subject to and effective  upon the acceptance for exchange of
the principal  amount of Existing Notes tendered in accordance  with this Letter
of  Transmittal,  the undersigned  sells,  assigns and transfers to, or upon the
order of, the Company all right, title and interest in and to the Existing Notes
tendered hereby. The undersigned hereby irrevocably constitutes and appoints the
Exchange  Agent its agent and  attorney-in-fact  (with full  knowledge  that the
Exchange  Agent also acts as the agent of the Company  and as Trustee  under the
Indenture  for the  Existing  Notes and New Notes) with  respect to the tendered
Existing Notes with full power of substitution to (i) deliver  certificates  for
such Existing Notes to the Company, or transfer ownership of such Existing Notes
on the account books maintained by DTC and deliver all accompanying  evidence of
transfer and authenticity to, or upon the order of, the Company and (ii) present
such  Existing  Notes for  transfer  on the books of the Company and receive all
benefits  and  otherwise  exercise  all rights of  beneficial  ownership of such
Existing  Notes,  all in accordance with the terms and subject to the conditions
of the Exchange Offer.  The power of attorney granted in this paragraph shall be
deemed irrevocable and coupled with an interest.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Existing Notes
tendered  hereby and that the Company will acquire good and  unencumbered  title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim, when the same are acquired by the Company. The
undersigned  hereby further  represents  that any New Notes acquired in exchange
for  Existing  Notes  tendered  hereby will have been  acquired in the  ordinary
course of business of the Holder  receiving such New Notes,  whether or not such
person is the Holder,  that neither the Holder nor any such other person has any
arrangement or understanding  with any person to participate in the distribution
of such New Notes and that  neither  the Holder nor any such other  person is an
"affiliate,"  as defined in Rule 405 under the Securities Act, of the Company or
any of its subsidiaries.

         The  undersigned  also  acknowledges  that this Exchange Offer is being
made in  reliance  on an  interpretation  by the  staff  of the  Securities  and
Exchange  Commission  (the "SEC") that the New Notes  issued in exchange for the
Existing Notes pursuant to the Exchange Offer may be offered for resale,  resold
and otherwise transferred by holders thereof (other than any such holder that is
an  "affiliate"  of the  Company  within  the  meaning  of Rule  405  under  the
Securities  Act),  without  compliance  with  the  registration  and  prospectus
delivery  provisions  of the  Securities  Act,  provided that such New Notes are
acquired in the ordinary course of such holders'  business and such holders have
no  arrangements  or  understandings  with  any  person  to  participate  in the
distribution of such New Notes. If the undersigned is not a  broker-dealer,  the
undersigned  represents that it is not engaged in, and does not intend to engage
in, a distribution of New Notes. If the undersigned is a broker-dealer that will
receive New Notes for its own account in exchange for  Existing  Notes that were
acquired as a result of market-making activities or other trading activities, it
acknowledges  that it will deliver a prospectus in connection with any resale of
such New Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an  "underwriter"  within the
meaning of the Securities Act.

         The undersigned will, upon request,  execute and deliver any additional
documents  deemed  by the  Exchange  Agent or the  Company  to be  necessary  or
desirable  to complete  the  assignment,  transfer  and purchase of the Existing
Notes tendered hereby. All authority conferred or agreed to be conferred by this
Letter of Transmittal shall survive the death,  incapacity or dissolution of the
undersigned  and  every  obligation  of the  undersigned  under  this  Letter of
Transmittal   shall  be  binding   upon  the   undersigned's   heirs,   personal
representatives,  successors and assigns,  trustees in bankruptcy or other legal
representatives  of the  undersigned.  This  tender  may be  withdrawn  only  in
accordance  with the  procedures  set forth in "The Exchange  Offer - Withdrawal
Rights" section of the Prospectus.

         For purposes of the Exchange Offer, the Company shall be deemed to have
accepted validly  tendered  Existing Notes when, as and if the Company has given
oral or written notice thereof to the Exchange Agent.

         If any tendered  Existing Notes are not accepted for exchange  pursuant
to the  Exchange  Offer for any  reason,  certificates  for any such  unaccepted
Existing  Notes will be returned  (except as noted below with respect to





tenders through DTC),  without expense,  to the undersigned at the address shown
below or at such different  address as may be indicated under "Special  Delivery
Instructions" as promptly as practicable after the Expiration Date.

         The undersigned  understands that tenders of Existing Notes pursuant to
the procedures  described under the caption "The Exchange Offer - Procedures for
Tendering Existing Notes" in the Prospectus and in the instructions  hereto will
constitute a binding  agreement between the undersigned and the Company upon the
terms and subject to the conditions of the Exchange Offer.

         Unless  otherwise  indicated  under  "Special  Issuance  Instructions,"
please issue the certificates  representing the New Notes issued in exchange for
the Existing  Notes  accepted  for  exchange  and return any Existing  Notes not
tendered or not accepted for exchange in the name(s) of the  undersigned  (or in
either such event in the case of the  Existing  Notes  tendered  through DTC, by
credit  to the  undersigned's  account  at  DTC).  Similarly,  unless  otherwise
indicated under "Special  Delivery  Instructions,"  please send the certificates
representing  the New Notes issued in exchange for the Existing  Notes  accepted
for  exchange  and any  certificates  for  Existing  Notes not  tendered  or not
accepted  for exchange  (and  accompanying  documents,  as  appropriate)  to the
undersigned at the address shown below the undersigned's  signature(s),  unless,
in either  event,  tender is being  made  through  DTC.  In the event  that both
"Special  Issuance   Instructions"  and  "Special  Delivery   Instructions"  are
completed,  please issue the  certificates  representing the New Notes issued in
exchange  for the Existing  Notes  accepted for exchange and return any Existing
Notes not tendered or not accepted for exchange in the name(s) of, and send said
certificates to, the person(s) so indicated. The undersigned recognizes that the
Company has no obligation  pursuant to the "Special  Issuance  Instructions" and
"Special Delivery  Instructions" to transfer any Existing Notes from the name of
the registered Holder(s) thereof if the Company does not accept for exchange any
of the Existing Notes so tendered.

         Holders of Existing  Notes who wish to tender their  Existing Notes and
(i)  whose  Existing  Notes are not  immediately  available  or (ii) who  cannot
deliver their Existing Notes,  this Letter of Transmittal or any other documents
required  hereby to the Exchange  Agent,  or cannot  complete the  procedure for
book-entry  transfer,  prior to the  Expiration  Date, may tender their Existing
Notes  according  to  the  guaranteed  delivery  procedures  set  forth  in  the
Prospectus  under  the  caption  "The  Exchange  Offer  -  Guaranteed   Delivery
Procedures."  See  Instruction  1  regarding  the  completion  of the  Letter of

                                  INSTRUCTIONS

                    Forming Part of the Terms and Conditions
                              of the Exchange Offer

         1.  Delivery  of  this  Letter  of  Transmittal   and  Existing  Notes;
Guaranteed Delivery Procedures. This Letter of Transmittal is to be completed by
Holders,  either if certificates are to be forwarded  herewith or if tenders are
to be made pursuant to the  procedures  for delivery by book-entry  transfer set
forth in "The Exchange Offer - Book-Entry  Transfer"  section of the Prospectus.
Certificates  for  all  physically   tendered   Existing  Notes,  or  Book-Entry
Confirmation,  as the  case may be,  as well as a  properly  completed  and duly
executed  Letter of Transmittal (or manually  signed  facsimile  hereof) and any
other documents required by this Letter of Transmittal,  must be received by the
Exchange  Agent at one of the  addresses  set  forth  herein  on or prior to the
Expiration  Date,  or the  tendering  Holder  must  comply  with the  guaranteed
delivery  procedures set forth below.  Existing Notes tendered hereby must be in
denominations of principal amount of $1,000 and any integral multiple thereof.

         Holders  whose  certificates  for  Existing  Notes are not  immediately
available  or who  cannot  deliver  their  certificates  and all other  required
documents  to the  Exchange  Agent on or prior to the  Expiration  Date,  or who
cannot  complete the procedure for  book-entry  transfer on a timely basis,  may
tender their Existing Notes pursuant to the guaranteed  delivery  procedures set
forth in "The Exchange Offer - Guaranteed  Delivery  Procedures"  section of the
Prospectus. Pursuant to such procedures, (i) such tender must be made through an
Eligible  Institution  (as defined in  Instruction  4 below),  (ii) prior to the
Expiration Date, the Exchange Agent must receive from such Eligible  Institution
a properly  completed  and duly  executed  Letter of  Transmittal  (or facsimile
thereof) and Notice of Guaranteed Delivery (by facsimile  transmission,  mail or
hand delivery), substantially in the form provided by the Company, setting forth
the name and address of the Holder of Existing  Notes and the amount of Existing
Notes tendered,  stating that the tender is being made thereby and  guaranteeing
that,  within five New York Stock Exchange  ("NYSE") trading days after the date
of execution of the Notice of  Guaranteed  Delivery,  the  certificates  for all
physically tendered Existing Notes, or a Book-Entry Confirmation,  and any other
documents  required  by this  Letter of  Transmittal  will be  deposited  by the
Eligible Institution with the Exchange Agent, and (iii) the certificates for all
physically tendered Existing Notes, in proper form for transfer, or a Book-Entry
Confirmation,  as the case may be,  and all  other  documents  required  by this
Letter of  Transmittal,  are  received by the  Exchange  Agent  within five NYSE
trading days after the date of execution of the Notice of Guaranteed Delivery.

         THE METHOD OF  DELIVERY  OF THIS LETTER OF  TRANSMITTAL,  THE  EXISTING
NOTES  AND ALL  OTHER  REQUIRED  DOCUMENTS  IS AT THE  ELECTION  AND RISK OF THE
TENDERING  HOLDERS,  BUT THE  DELIVERY  WILL BE DEEMED  MADE ONLY WHEN  ACTUALLY
RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT. IF EXISTING NOTES ARE SENT BY MAIL,
IT IS  SUGGESTED  THAT  THE  MAILING  BE MADE  SUFFICIENTLY  IN  ADVANCE  OF THE
EXPIRATION DATE TO PERMIT THE DELIVERY TO THE EXCHANGE AGENT PRIOR TO 5:00 P.M.,
NEW YORK CITY TIME, ON THE EXPIRATION DATE.

         See "The Exchange Offer" section in the Prospectus.

         2. Tender by Holder.  Only a Holder of  Existing  Notes may tender such
Existing Notes in the Exchange  Offer.  Any beneficial  holder of Existing Notes
who is not the  registered  Holder and who wishes to tender should  arrange with
the  registered  Holder to execute and deliver this Letter of Transmittal on his
or her  behalf  or must,  prior to  completing  and  executing  this  Letter  of
Transmittal  and delivering his or her Existing Notes,  either make  appropriate
arrangements  to register  ownership of the Existing Notes in such holder's name
or obtain a properly completed bond power from the registered Holder.

         3. Partial Tenders.  Tenders of Existing Notes will be accepted only in
integral  multiples of $1,000.  If less than the entire  principal amount of any
Existing  Notes is tendered,  the tendering  Holder should fill in the principal
amount  tendered in the fourth  column of the box entitled  "Description  of 13%
First Mortgage Notes due 2005 With Contingent  Interest (Existing Notes)" above.
The entire  principal  amount of Existing Notes  delivered




to the  Exchange  Agent will be deemed to have been  tendered  unless  otherwise
indicated.  If the entire principal  amount of a Holder's  Existing Notes is not
tendered,  then Existing  Notes for the principal  amount of Existing  Notes not
tendered and a  certificate  or  certificates  representing  New Notes issued in
exchange for any Existing Notes accepted for exchange will be sent to the Holder
at his or her registered  address (unless a different address is provided in the
appropriate box on this Letter of Transmittal) promptly after the Existing Notes
are accepted for exchange.

         4. Signatures on this Letter of Transmittal; Endorsements and Powers of
Attorney;  Guarantee of  Signatures.  If this Letter of Transmittal is signed by
the registered Holder of the Existing Notes tendered hereby,  the signature must
correspond  exactly  with the name as  written  on the face of the  certificates
without any change whatsoever.

         If any tendered Existing Notes are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.

         If any tendered  Existing  Notes are  registered in different  names on
several certificates,  it will be necessary to complete, sign and submit as many
separate   copies  of  this  Letter  of   Transmittal  as  there  are  different
registrations of certificates.

         When this Letter of Transmittal  is signed by the registered  Holder(s)
of the Existing Notes specified herein and tendered  hereby,  no endorsements of
certificates or separate bond powers are required.  If,  however,  the New Notes
are to be  issued,  or any  Existing  Notes not  tendered  or not  accepted  for
exchange are to be reissued,  to a person or persons  other than the  registered
Holder(s),  then  endorsements  of  any  certificate(s)  transmitted  hereby  or
separate bond powers are required. Signatures on such certificate(s) or power(s)
must be guaranteed by an Eligible Institution.

         If this  Letter of  Transmittal  is signed by a person  other  than the
registered Holder(s) of any certificate(s) specified herein, such certificate(s)
must be  endorsed  or  accompanied  by  appropriate  bond  powers  or  powers of
attorney,  in each case  signed  exactly as the name or names on the  registered
Holder(s)  appear(s) on the certificate(s) and signatures on such certificate(s)
or power(s) must be guaranteed by an Eligible Institution.

         If this  Letter of  Transmittal  or any  certificates,  bond  powers or
powers of attorney are signed by trustees, executors, administrators, guardians,
attorneys-in-fact,  officers of  corporations or others acting in a fiduciary or
representative  capacity,  such  persons  should so indicate  when  signing and,
unless waived by the Company,  proper  evidence  satisfactory  to the Company of
their authority to so act must be submitted.

         Endorsements on  certificates  for Existing Notes or signatures on bond
powers or powers of attorney  required by this  Instruction 4 must be guaranteed
by a firm which is a participant in a recognized  signature  guarantee medallion
program (an "Eligible Institution").

         Signatures  on this  Letter of  Transmittal  must be  guaranteed  by an
Eligible  Institution unless the Existing Notes are tendered (i) by a registered
Holder of Existing  Notes  (which  term,  for  purposes of the  Exchange  Offer,
includes any DTC participant  whose name appears on a security  position listing
as the Holder of such  Existing  Notes) who has not  completed  the box entitled
"Special  Issuance  Instructions"  or "Special  Delivery  Instructions"  on this
Letter of Transmittal, or (ii) for the account of an Eligible Institution.

         5. Special Issuance and Delivery Instructions. Tendering Holders should
indicate,  in the  applicable  box or boxes,  the name and  address to which New
Notes or substitute Existing Notes not tendered or not accepted for exchange are
to be issued or sent,  if  different  from the name and  address  of the  person
signing this Letter of Transmittal (or in the case of a tender of Existing Notes
through  DTC,  if  different  from DTC).  In the case of issuance in a different
name, the taxpayer  identification or social security number of the person named
must also be indicated.  Holders tendering Existing Notes by book-entry transfer
may request that New Notes issued in exchange  for Existing  Notes  accepted for
exchange or Existing  Notes not tendered or accepted  for exchange  exchanged be




credited to such account  maintained at DTC as such Holder may designate hereon.
If no such  instructions  are  given,  such New  Notes  or  Existing  Notes  not
exchanged  will be returned to the name and address of the person  signing  this
Letter of Transmittal.

         6. Tax  Identification  Number.  Federal income tax law requires that a
Holder whose  Existing  Notes are accepted for exchange must provide the Company
(as payer ) with his, her or its correct Taxpayer Identification Number ("TIN"),
which, in the case of an exchanging  Holder who is an individual,  is his or her
social security  number.  If the Company is not provided with the correct TIN or
an  adequate  basis for  exemption,  such Holder may be subject to a $50 penalty
imposed by the Internal  Revenue  Service (the  "IRS"),  and payments  made with
respect to the New Notes or Exchange Offer may be subject to backup  withholding
at a 31% rate. If  withholding  results in an overpayment of taxes, a refund may
be obtained.  Exempt Holders  (including,  among others,  all  corporations  and
certain  foreign  individuals)  are not subject to these backup  withholding and
reporting  requirements.  See the  enclosed  "Guidelines  for  Certification  of
Taxpayer Identification Number on Substitute Form W-9."

         To prevent backup withholding, each exchanging Holder must provide his,
her or its correct TIN by completing the  Substitute  Form W-9 included below in
this Letter of Transmittal, certifying that the TIN provided is correct (or that
such  Holder  is  awaiting  a TIN) and that the  Holder is  exempt  from  backup
withholding because (i) the Holder has not been notified by the IRS that he, she
or it is  subject to backup  withholding  as a result of a failure to report all
interest or  dividends,  or (ii) the IRS has notified the Holder that he, she or
it is no longer subject to backup  withholding.  In order to satisfy the Company
that a foreign  individual  qualifies as an exempt  recipient,  such Holder must
submit a statement  signed  under  penalty of perjury  attesting  to such exempt
status. Such statements may be obtained from the Exchange Agent. If the Existing
Notes  are in more  than one name or are not in the  name of the  actual  owner,
consult the substitute Form W-9 for  information on which TIN to report.  If you
do not provide your TIN to the Company within 60 days,  backup  withholding  may
begin and continue until you furnish your TIN to the Company.

         7. Transfer  Taxes.  The Company will pay all transfer  taxes,  if any,
applicable to the exchange of Existing Notes pursuant to the Exchange Offer. If,
however,  certificates  representing New Notes or Existing Notes not tendered or
accepted for exchange are to be delivered  to, or are to be registered or issued
in the  name of,  any  person(s)  other  than the  registered  Holder(s)  of the
Existing Notes tendered hereby,  or if tendered Existing Notes are registered in
the name of any person other than the person signing this Letter of Transmittal,
or if a transfer  tax is  imposed  for any reason  other  than the  exchange  of
Existing  Notes  pursuant  to the  Exchange  Offer,  then the amount of any such
transfer  taxes  (whether  imposed on the  registered  Holder(s) or on any other
person(s)) will be payable by the tendering Holder(s).  If satisfactory evidence
of payment of such taxes or exemption therefrom is not submitted  herewith,  the
amount  of  such  transfer  taxes  will be  billed  directly  to such  tendering
Holder(s).

         Except as provided in this  Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the Existing Notes listed in this Letter of
Transmittal.

         8. Waiver of  Conditions.  The Company  reserves the absolute  right to
amend,  waive or modify  conditions to in the Exchange  Offer in the case of any
Existing Notes tendered (and to refuse to do so).

         9. No Conditional Transfers. No alternative,  conditional, irregular or
contingent tenders will be accepted. All tendering Holders of Existing Notes, by
execution of this Letter of Transmittal, shall waive any right to receive notice
of the acceptance of their Existing Notes for exchange.

         Neither  the  Company,  the  Exchange  Agent  nor any  other  person is
obligated  to give  notice of any  defect or  irregularity  with  respect to any
tender of Existing Notes,  nor shall any of them incur any liability for failure
to give any such notice.




         10. Mutilated,  Lost, Stolen or Destroyed Existing Notes. Any tendering
Holder  whose  Existing  Notes have been  mutilated,  lost,  stolen or destroyed
should contact the Exchange Agent at one of the addresses  indicated  herein for
further instructions.

         11.  Requests  for  Assistance  or  Additional  Copies.  Questions  and
requests for assistance for additional copies of the Prospectus,  this Letter of
Transmittal,   the  Notice  of  Guaranteed   Delivery  or  the  "Guidelines  for
Certification  of Taxpayer  Identification  Number on Substitute Form W-9 may be
directed  to  the  Exchange  Agent  at one of  the  addresses  specified  in the
Prospectus.
