FOR IMMEDIATE RELEASE

SILICON GAMING AND INTERNATIONAL GAME TECHNOLOGY ANNOUNCE DEFINITIVE AGREEMENT
REGARDING MERGER TRANSACTION

PALO ALTO, CALIFORNIA, December 19, 2000 - Silicon Gaming, Inc. (OTCBB: SGIC.OB)
and International Game Technology (NYSE: IGT) announced today that they have
entered into a definitive agreement pursuant to which Silicon would be merged
into a subsidiary of International Game Technology in a cash-for-stock merger.
The consummation of the merger is subject to stockholder approval, gaming
regulatory approvals, third-party consents and the satisfaction of other closing
conditions. Either party may terminate the agreement if the merger has not been
consummated by May 30, 2001.

Under the terms of the proposed transaction, the total consideration paid by
International Game Technology would be approximately $45 million. The amount
paid would be increased by the amount of certain Silicon current assets on hand
at closing and reduced by the amount of all indebtedness and other liabilities
of Silicon at closing, including any unpaid Silicon transaction expenses.

After giving effect to the conversion of Silicon's preferred stock and the
exercise of outstanding options and warrants, it is anticipated that there would
be in excess of 285 million shares of common stock outstanding at the time of
closing of the proposed transaction. Based upon Silicon's current assumptions,
it is estimated that Silicon stockholders (including holders of preferred stock
who would participate on an "as converted" basis) would receive approximately
$0.0825 to $0.0950 per share. This estimate is based on a number of

uncertainties, and there can be no assurance that the amount of per share merger
consideration will fall within the estimated range set forth above.

As part of the proposed transaction, Silicon has agreed that prior to the
closing of the proposed merger, it will dispose of its shares of WagerWorks,
Inc. ("WagerWorks"), a majority-owned subsidiary of Silicon, other than a number
of shares that would equal 4.9% of WagerWorks on a fully-diluted basis. Silicon
is evaluating various options regarding the disposition of its shares of
WagerWorks. The estimated per-share proceeds stated above do not include any
estimated amounts to be received from the sale of the shares of WagerWorks, if
any. When and if the sale of the shares of WagerWorks is consummated, the per
share consideration paid to stockholders of Silicon (including holders of
preferred stock who would participate on an "as converted" basis) estimated in
the previous paragraph could increase. WagerWorks is a privately held company
and there is no trading market for its shares. We cannot predict with any
certainty what the selling price of those shares will be.

Silicon engaged US Bancorp Libra, a division of US Bancorp Investments, Inc., to
analyze the fairness of the transaction from a financial point of view. US
Bancorp Libra delivered an opinion that the proposed merger transaction was fair
to the equity holders of Silicon, taken as a whole, from a financial point of
view.
