                                                               Las Vegas, Nevada
$500,000.00                                                       March 16, 2005

      FOR VALUE  RECEIVED,  the  undersigned,  WIN WIN GAMING,  INC., a Delaware
corporation  with a mailing  address of 8687 West Sahara Avenue,  Suite 201, Las
Vegas,  NV 89117,  (the  "Borrower")  promises to pay to the order of ART PETRIE
with a principal  place of business  at and mailing  address of (the  "Lender"),
Asset  Development  Services,  LLC, 7235 Bermuda Road.,  Suite G, Las Vegas,  NV
89119,  or at such  other  place as the  holder  hereof  may  from  time to time
designate in writing,  the  principal  sum of Five  Hundred  Thousand and No/100
Dollars  ($500,000.00) (the "Loan") or so much as may be advanced and readvanced
by the Lender and remain unpaid from time to time, together with interest on the
principal  balance  of this  Note  outstanding  from  time to time from the date
hereof until this Note is paid in full, at the interest rate or rates and in the
manner hereinafter provided.

      The  principal  balance  of  the  indebtedness   evidenced  by  this  Note
outstanding  from time to time shall bear  interest,  from the date hereof until
said indebtedness shall have been paid in full, at a simple rate per annum equal
to twelve  percent  (12%).  Interest  shall be  calculated  on the daily  unpaid
principal  balance of the  indebtedness  evidenced by this Note based upon a 360
day year,  provided  that  interest  shall be due for the actual  number of days
elapsed during each period for which interest is charged.

      The payment of the principal sum then outstanding and all accrued interest
thereon shall be made at Maturity.  "Maturity" means the sooner of (a) the first
anniversary  of the date  hereof,  or (b) the date that the  Borrower is able to
consummate  an  equity  financing  transaction  in which the  Borrower  receives
aggregate gross proceeds of at least $1,000,000.

      On this date,  the Lender has advanced to the Borrower,  the sum of $0 and
agrees  to  advance  and  readvance  (each an  "Advance  and  collectively,  the
"Advances") to Borrower from time to time, up to the sum of $500,000.00.

      Lender's  agreement to make Advances shall terminate on the Maturity Date,
at which time, all principal,  interest and any other monies due under this Note
shall  become  due  and  payable,  unless  the  Maturity  Date is  extended,  as
hereinafter provided.

      The  Borrower  promises  to pay, in  addition  to said  principal  sum and
interest,  all taxes and assessments which may be levied against the Lender upon
this indebtedness, and all reasonable costs of collection and expenses including
reasonable  attorney's  fees incurred by the Lender to collect the  indebtedness
due hereunder.

      At the option of the  Lender,  the entire  principal  amount of this Note,
accrued interest thereon,  and all other amounts which the Borrower is obligated
to pay hereunder,  shall at once become due and payable  without notice upon the
occurrence  at any time of any of the following  events (each  referred to as an
"event of default" or a "default"):

      A. The failure to make any payment due hereunder; or
<PAGE>

      B. The filing by or against  the  Borrower of any  petition,  arrangement,
reorganization,  or the like under any applicable  insolvency or bankruptcy law,
or the  adjudication  of the  Borrower  as a  bankrupt  and if  such  filing  is
involuntary,  the failure to have the same dismissed within sixty (60) days from
the date of filing, or the making of an assignment for the benefit of creditors,
or the  appointment  of a  receiver  for any  part of  Borrower's  or any of the
Parties'  properties  or the  admission in writing by the Borrower or any of the
Parties of the inability to pay debts as they become due;

      Upon the occurrence of an event of default,  or upon Maturity hereof,  the
outstanding  principal balance of the indebtedness  evidenced by this Note shall
at the option of the Lender,  bear  interest from the date of occurrence of such
event of default or such Maturity until collection (including any period of time
occurring  after  judgment),  at the  "Default  Rate" being the lower of (a) the
highest  rate  allowed by law, or (b) a rate per annum equal to four  percentage
points  (4%)  above  the rate of  interest  that  would  otherwise  be in effect
hereunder, as the same may vary from time to time.

      The Lender may waive any right or remedy  hereunder.  No delay on the part
of the Lender in the  exercise  of any such right or remedy  shall  operate as a
waiver thereof. A waiver on one occasion shall not be construed as a bar to or a
waiver of any such right or remedy on any future occasion. No remedy reserved to
the Lender hereunder is intended to be exclusive of any other remedy,  including
those available at law or equity, and each shall be cumulative to others and may
be exercised singularly or concurrently.

      Borrower  may  prepay  this  Note in whole or in part at any time  without
penalty or premium.  All prepayments  shall be accompanied by payment of accrued
interest and any other charges  outstanding under this Note. Lender is obligated
to readvance  prepaid  amounts in accordance  with the fourth  paragraph of this
Note.

      Any  notice  or  demand to any party  hereto  shall be  delivered  by hand
delivery,  express mail, registered mail, return receipt requested,  first class
mail or by facsimile  transmission  addressed to each party at the addresses set
forth at the  beginning  of this Note or such other  address as either party may
hereafter  designate in writing in the manner  provided  herein and such service
shall be deemed complete on receipt or refusal to accept.

      The Borrower hereby represents,  covenants and agrees that the proceeds of
the Loan shall be used for general  commercial  purposes  and that the Loan is a
commercial transaction.

      All  references to the  "Lender",  the  "Borrower" or the "Parties"  shall
apply to their respective heirs, successors and assigns.

      Presentment, protest and notice are hereby waived.

      IN WITNESS  WHEREOF,  the  undersigned  Borrower and Lender have evidenced
this  Revolving  Line of Credit Note and Agreement by signing  their  respective
names in the spaces provided below as of the date first above written.

                                                 WIN WIN GAMING, INC.
