ITEM 1:  SECURITY AND ISSUER

     This Amendment No. 1 to the statement on Schedule 13D originally filed on
November 26, 2003 relates to the Class A common stock, par value $0.01 per share
("Common Stock"), of Scientific Games Corporation, a Delaware corporation (the
"Issuer").

ITEM 3:  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     Item 3 is hereby amended by inserting the following immediately after the
last paragraph thereof:

     On August 4, 2004, following the Conversion (as defined in Item 5), SGMS
Acquisition Corporation ("SAC"), a wholly-owned subsidiary of Mafco Holdings
Inc., increased the amount of Common Stock pledged to each of Bank of America
and HSBC in connection with certain loan transactions.

ITEM 4:  PURPOSE OF TRANSACTION

     Item 4 is hereby amended by inserting the following immediately after the
last paragraph thereof:

     SAC elected to effect the Conversion in view of the fact that under the
terms of the Series A Certificate, the Issuer would otherwise have had the
right, beginning on or about August 21, 2004, to redeem all of the Series A
Shares for 105% of the liquidation preference of those shares, which was
approximately 34% of the market value of the Common Stock underlying the Series
A Shares at the time of conversion. The Conversion will not affect SAC's right
to designate up to four members of the Issuer's board of directors and to
approve certain significant corporate transactions. SAC has no current intention
of reducing its investment in the Issuer.

ITEM 5:  INTEREST IN SECURITIES OF THE ISSUER

     Item 5 is hereby amended by inserting the following immediately after the
penultimate paragraph thereof:

     On August 3, 2004, SAC converted all of its 1,218,479 Series A Shares into
21,915,089 shares of Common Stock pursuant to the terms of the Series A
Certificate (the "Conversion"). Concurrently with the Conversion, the Issuer
redeemed all of SAC's 1,097.664 Series B Shares pursuant to the terms of the
Series B Certificate for an aggregate redemption price of $1,097.67.

     According to the Issuer's Quarterly Report on Form 10-Q for the quarter
ended March 31, 2004, there were, as of May 7, 2004, 63,168,281 shares of Common
Stock issued and outstanding. Based on the foregoing, immediately following the
Conversion, SAC had sole voting power and sole dispositive power over 25.8% of
the Common Stock.

                                       4




     On August 5, 2004, Howard Gittis purchased 10,000 shares of Common Stock
and Barry Schwartz purchased 5,000 shares of Common Stock, in each case in the
open market. The average price paid by Mr. Gittis was $16.48 per share and the
average price paid by Mr. Schwartz was $17.01 per share. In addition, the Issuer
granted each of the New Directors 1,781 shares of restricted Common Stock on
January 2, 2004 pursuant to its director compensation policies.

                                        5
