We are offering 4,692,866 shares of our Common Stock, par value $0.0001 per share (the “ Common Stock”), pursuant to this Prospectus Supplement and accompanying Prospectus and, in lieu of Common Stock to investors that so choose, pre-funded warrants to purchase up to 3,728,188 shares of our Common Stock in this offering. The purchase price of each pre-funded warrant will equal the price per share at which shares of our Common Stock are being sold to the public in this offering, minus $0.0001, which will be the exercise price of each pre-funded warrant. Each pre-funded warrant will be exercisable for one share of Common Stock. The pre-funded warrants do not expire, and each pre-funded warrant will be exercisable at any time after the date of issuance. This Prospectus Supplement also relates to the offering of the shares of our Common Stock issuable upon the exercise of such pre-funded warrants.

Our Common Stock is listed on The Nasdaq Capital Market (“ NASDAQ”) under the symbol “GAME.” On July 3, 2025, the last reported sale price of our Common Stock on NASDAQ was $0.89.

See “Summary- Implications of Being an Emerging Growth Company and a Smaller Reporting Company.”

As of July 3, 2025, the aggregate market value of our outstanding Common Stock held by non-affiliates (“ Public Float”) was approximately $27.8 million based on 39,123,968 shares of outstanding Common Stock as of July 3, 2025, of which 9,904,523 shares were held by our affiliates, and a price of $0.95 per share on June 9, 2025, which was the highest closing sale price of our Common
