MDI LETTERHEAD]

Exhibit 99(a)(6)

        [MDI LETTERHEAD]

December 13, 2002

To: Holders of Warrants to Purchase Common Stock of MDI Entertainment, Inc.

        This letter concerns your warrants to purchase shares of MDI Entertainment, Inc. ("MDI") common stock, par value $0.001 (referred to in this letter as "Warrants"). As you may know, on November 19, 2002, MDI entered into a merger agreement (the "Merger Agreement") with Scientific Games International, Inc. ("Scientific Games") and its wholly owned subsidiary ("Purchaser").¹ The Merger Agreement provides, as a first step in the acquisition of MDI, that the Purchaser will make a tender offer to purchase all of MDI's outstanding common stock at a price of $1.60 per share in cash. The tender offer is currently scheduled to close at midnight on Friday, December 27, 2002. However, this tender offer is subject to certain conditions, one of which is that the Purchaser shall acquire more than 75% of MDI's outstanding common stock on a fully-diluted basis. We refer to this tender offer as the "Offer," and any references in this letter to the Offer include any extension and any subsequent offering period provided under the Merger Agreement. Assuming that the conditions to the Offer are met and that the Offer closes, because Purchaser will have acquired more than a majority of MDI's common stock, following the Offer, Purchaser will have enough votes to complete the merger of Purchaser with MDI (the "Merger"). As a result of the Merger, MDI will become a direct, wholly owned subsidiary of Scientific Games.

A copy of the Merger Agreement and the press release announcing the Offer and the Merger are available as attachments to MDI's Form 8-K filed with the SEC on November 20, 2002.

        All holders of outstanding shares of MDI's common stock at the time of the Merger who did not tender their shares in the Offer will receive cash consideration in the amount of $1.60 per share following the closing of the Merger unless they choose to exercise their statutory appraisal rights as described in the Offer to Purchase. If you did not receive the Offer to Purchase, MDI's Solicitation/Recommendation Statement and other tender offer materials which were sent to all stockholders of MDI, please contact Innisfree at (000) 000-0000 and a copy of these materials will be sent to you.

        You may choose to exercise each of your Warrants and tender all of the shares of common stock underlying such Warrants (the "Warrant Shares") to Purchaser pursuant to the Offer by completing the Warrant Election form attached hereto as Annex A. Although you are not required to do so, tendering your Warrant Shares pursuant to the Offer will allow you to receive cash for your shares earlier (promptly after the Offer closes) than if you wait until the Merger occurs to receive cash for your shares. By completing and signing such Warrant Election form, you agree that, immediately prior to the purchase of shares of MDI's common stock by Purchaser in the Offer, and contingent upon the anticipated completion of such purchase (as determined by MDI), you shall be deemed to have fully exercised each such Warrant and to have tendered each of the Warrant Shares to Purchaser pursuant to the Offer. By electing now to conditionally exercise and then tender your Warrant Shares in this manner, you will be entitled to receive payment for your Warrant Shares promptly after the closing of the Offer and prior to the closing of the Merger. If MDI does not anticipate that the Offer will be consummated, your Warrants will not be exercised and you will still have all of your currently existing rights with respect to your Warrants. In addition, MDI will return your Warrant exercise price if you have previously delivered a check.

        Alternatively, pursuant to the terms of the Merger Agreement, and as permitted under the terms of the applicable Warrant agreement, as of the effective time of the Merger, each outstanding Warrant, will be, immediately prior to the effective time of the Merger, cancelled. In consideration of such cancellation, you will receive an amount equal to the product of (i) the excess, if any, of the $1.60 offer price over the exercise price of each such Warrant and (ii) the number of Warrant Shares subject to such Warrants. After the closing of the Merger, the Warrants will terminate and all rights under any

provision of any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of MDI will be cancelled.

        The purpose of this letter is to provide you notice of the Offer and Merger pursuant to the Merger Agreement and important information about how you may receive payment for your Warrants. To be certain that you are able to exercise your Warrants and tender the Warrant Shares in the Offer, you must return the attached Warrant Election form to Xxxxxxx Xxxxxxxxxx in the enclosed envelope prior to noon on December 26, 2002. You may exercise your Warrant by (i) cashless exercise or (ii) including payment in full of the exercise price by check made payable to MDI Entertainment, Inc. If you do not exercise your Warrants and tender the Warrant Shares prior to the expiration of the Offer (which may be as early as December 27, 2002), you will receive consideration for your Warrants upon the closing of the Merger pursuant to the terms of the Merger Agreement.

If you exercise your Warrants, we also request that you review carefully the Offer to Purchase and MDI's Solicitation/Recommendation Statement and consider whether to tender the shares underlying your Warrants in the Offer pursuant to the attached Warrant Election form.

        In addition, because individual circumstances may vary, each holder of Warrants should consult its own tax advisor to determine the particular tax consequences of the exercise of the Warrants and tender of the Warrant Shares in the Offer (or exchange in the Merger), including the application and effect of the alternative minimum tax and any state, local and foreign tax laws and the effect of any changes in such laws.

        Please feel free to contact Xxxxxxx Xxxxxxxxxx at (000) 000-0000 with any further questions you may have regarding your Warrants or the information in this letter.

Sincerely,


Xxxxxx X. Xxxxxxx
