Overwolf's ad monetization business Nitro has opened a $65,000 contest for free browser games made with Base44, the AI app builder run by Wix, according to the official contest page and a November 5 post on the Nitro blog by Assaf R. Shrim. Submissions close December 3, 2026, at 23:59 UTC.
Under the official terms, entrants must be 18 or older and need only a free Base44 account. Each entry must be a new game built during the submission period, free to play in full in a browser with no login or payment, and kept live for at least 90 days after winners are named. The contest page and blog post add that games must be hosted on a Base44 URL.
A judges' track pays $25,000, $10,000 and $5,000 plus $1,000 each to 10 runners-up. The contest page names the judges as Base44 CEO Maor Shlomo, Overwolf CEO Uri Marchand and Nitro founder Cody Bye, though the terms let Overwolf change the panel. A $15,000 community track pays $5,000 to first place and $1,000 to 10 runners-up.
Despite the "Community Vote" billing, upvotes on Base44 Launchpad only set a shortlist of the 25 most-upvoted games; a panel of Base44 staff appointed by Overwolf ranks them, as both the FAQ and the terms say. On teams, the FAQ says entry is individual only, while the terms, which prevail, allow teams of up to four.
Entrants keep ownership, but section 11.2 of the terms grants Overwolf and its affiliates a non-exclusive, royalty-free license that is "perpetual, irrevocable, transferable and sublicensable" to run the contest, promote Overwolf, Nitro and Base44 products, and showcase games on Overwolf properties. Base44 gets the same license for running and promotion.
Why it matters: This is a sizable cash pool for games made with an AI app builder. But the license lets the sponsors use any entry in marketing indefinitely without royalties, so anyone hoping to sell or license their game later should read the terms first.
Caveat: The promise that top games will be featured on the Overwolf Appstore is the sponsors', with no published criteria. A Nitro ad report released alongside claims browser games earn 2.37 times more revenue than their share of sessions; that figure comes from Nitro's own network data, and AIGamer hasn't read the gated report.
Judging runs December 4 to 9, and winners are due on or about December 10, 2026.
