The math of mobile gaming has never been comfortable for the companies that make games. Even the best-performing titles convert only a sliver of their players into paying customers. New industry data from Unity, the maker of the engine that powers a large share of the world’s mobile games, puts a number on the problem: among the top 25% of games, only 1.4% of daily active users make a purchase, meaning roughly 98.6% of players pay nothing at all.
The figures, drawn from Unity Analytics data covering 2023 through 2025, arrive as the industry’s two traditional growth levers are weakening. The cost of acquiring a new player has climbed steadily, as ad prices rose and privacy restrictions made targeting harder. Growth in spending on in-app purchases has slowed. And the business remains uncomfortably dependent on a tiny group of whales: data from 2024 showed that just 10% of high-spending users contribute about 60% of a game’s revenue.
That dependence is what Unity says it can fix. The company is making the case that offerwall advertising, a monetization model in which players voluntarily watch ads, download apps, or complete tasks in exchange for in-game currency or rewards, can bring the other 98.6% into the game economy. Rather than asking players to open their wallets, the model lets them earn their way in with time and attention.
Unity’s argument rests on retention data from its own platform. According to the company’s 2024 Mobile Growth and Monetization Report, players acquired through offerwall conversions show higher long-term retention than ordinary players, with day-seven, day-30, and day-90 retention rates of roughly 55.0%, 33.8%, and 14.2%, respectively. Those figures, if they hold across a broad set of titles, would make offerwall one of the more efficient ways to build a stable base of engaged users.
The pitch comes at a moment when game companies are hunting for revenue wherever they can find it. Mobile gaming, which accounts for roughly half of the global games market, has matured: the explosive growth of the early smartphone era is over, and publishers are being asked to squeeze more from existing audiences rather than find new ones. Offerwall is one of the few models that grows revenue without raising prices or pushing harder on the minority of players who already pay.
The model has a checkered history. Early versions of offerwall, a decade ago, were associated with low-quality advertisers and deceptive practices, and some stores restricted them. The modern version, run by companies such as Tapjoy and others that integrate with Unity’s advertising platform, is closer to rewarded advertising, the industry’s term for letting players watch ads in exchange for in-game benefits. Unity’s data suggests the stigma has faded as the quality of advertisers has improved.
There are limits, analysts said. Offerwall works best in games with virtual economies, where currency has clear value, and it suits mid-core and casual titles more than narrative games that players finish quickly. It also carries opportunity cost: a player watching ads to earn currency is not spending real money, and publishers must calibrate how generous to be. Done badly, offerwall trains players to expect rewards for free; done well, it turns formerly free users into regulars who eventually pay.
Unity’s own position adds weight to the argument. The company, whose engine is used in most of the world’s mobile games, spent years building an advertising business to complement its software, and its merger with the ad-tech firm ironSource in 2022 made ad monetization a core part of its revenue. The offerwall push lets Unity sell publishers on a single platform that both powers the game and monetizes it, a combination competitors have struggled to match.
The economics explain why publishers are listening. A typical mid-core game spends heavily to acquire players through app-store ads, then converts only a small fraction of them into paying customers. Every non-paying player who remains active is, in that accounting, a small loss, a user whose acquisition cost was never recovered. Offerwall flips the math: the same player generates revenue through ad views and task completions, and the developer no longer needs the player to open a wallet for the session to pay for itself. In markets where in-app purchase spending is low, particularly in parts of Southeast Asia, Latin America, and Eastern Europe, that distinction can be the difference between a profitable game and a money-losing one.
Unity’s position in the industry gives its data unusual authority. Its analytics platform tracks hundreds of thousands of games, and its advertising network connects publishers with a large pool of advertisers, including many of the mobile apps that appear in offerwall task lists. The company’s own revenue depends on the model working, which invites skepticism, but publishers said the retention figures align with what they see in their own dashboards. The debate now is not whether offerwall works, but how much of a game’s economy should be built on it.
The broader message is about the industry’s next chapter. With acquisition costs rising and in-app purchase growth stalling, publishers face a choice between squeezing existing payers harder or finding ways to monetize the majority who never pay. Unity is betting that the second path is bigger, and its retention data is the evidence it will use to make that case to the developers who build on its platform.
