Rewarded user acquisition can bring a game new players, but an install is only the start of the test. Judge a campaign by what players do afterward, whether their value repays the cost, and whether the reward and task create a fair experience. Survey results are encouraging, but they do not prove that rewarded UA improves retention or pays off for every game.
What is rewarded user acquisition?
Reward-based user acquisition (rewarded UA) offers someone a reward for installing or playing an advertised game. The reward might be in-game currency, premium content, or something with real-world value. The task can be as simple as installing the game or can require a meaningful action, such as registering or reaching a specified level.
An offerwall is one way these campaigns may be presented: an app hosts offers, and a third party may certify whether a player completed the required action. A 2020 measurement study documented this model and its potential to affect store metrics; it is a historical description, not a current vendor directory or endorsement.
Rewarded UA is not rewarded video
Rewarded UA brings a player to a game through an offer tied to an install or other task. In rewarded advertising, an existing player receives a reward for watching an ad inside a game. The formats overlap in their use of incentives, but they address different points in the player journey and should be measured separately.

Does rewarded UA actually improve retention?
Almedia announced in January 2025 that a survey of 502 mobile game developers in the United States and United Kingdom found many respondents viewed reward-based campaigns favorably. Almedia is active in this category, and the figures below are respondents’ reports—not results from a controlled performance trial.
| Survey finding | What respondents reported |
|---|---|
| Campaign use | 77% of developers surveyed by Almedia in 2025 had run a reward-based marketing campaign. |
| Performance versus traditional marketing | 82% of those surveyed by Almedia in 2025 reported that reward-based campaigns outperformed their traditional marketing efforts. |
| Retention | 79% of those surveyed by Almedia in 2025 reported stronger player retention from these campaigns. |
| Planned investment | 59% of those surveyed by Almedia in 2025 planned to scale investment in rewarded channels during 2025; this was a stated plan, not evidence that the investment occurred. |
These survey responses do not establish that rewarded UA caused the reported retention differences, that every game will see the same result, or that campaigns delivered a particular return on ad spend. A 2025 study of app-install advertising at one US-based mobile game developer estimated that each $100 spent on ads was associated with 37 paid installs and three organic installs, with spillovers making advertising about 7.5% more effective than paid-install metrics alone suggested. That bounded result is not specific proof of a rewarded-UA effect and should not be applied as a universal multiplier.
Evidence about the ad experience is useful context, but it answers a different question from whether a rewarded acquisition campaign retains players. Google’s August 2026 Insights summary of a Deloitte and Google AdMob study reports survey responses about high-quality ads: 72% of surveyed gamers who experienced them continued playing immediately, and 20% said they played more often when ads were consistently well-executed. Deloitte’s 2025 release describes a global survey of 7,000 gamers and a diary study with 50 participants in Brazil, Germany, Japan, the United Kingdom, and the United States, conducted in early 2025. It reports a 6% to 7% increase in churn among surveyed users after one exposure to a disruptive ad feature and says repeated exposure led 52% of surveyed gamers to quit entirely. These findings concern ad experiences and reported behavior; they are not a promised retention lift for an acquisition campaign.

How should you evaluate a rewarded campaign?
Compare campaigns on the users’ behavior after the reward event, not only on the cost of getting an install. Decide in advance what counts as a valuable player for your game and how long you will observe them.
- Specify the task and audience. Write down the action that earns the reward and why it signals potential interest in the game. An install is a weaker quality signal than a relevant progression or engagement event, though a more demanding task can also limit participation.
- Choose post-install outcomes. Track meaningful steps such as onboarding completion, return visits, progression, or durable revenue. Select a retention window and value window before launch rather than choosing whichever result looks favorable afterward.
- Calculate economics over the same window. Compare campaign cost with the value of retained users and state the payback period. A low cost per install (CPI) is not evidence of efficiency if players leave before producing value.
- Check the player experience. Review whether the offer explains the task, reward, timing, eligibility, and completion rules clearly. Preserve player choice and check for disruptive ad behavior, misleading interactions, or a poor experience in either the host app or advertised game.
- Review measurement coverage. Confirm which events can be observed, when attribution data arrives, and which fields may be unavailable. Treat paid-to-organic spillover as a possibility to test, not an automatic credit to every campaign.
- Audit campaign integrity. Look for invalid traffic, artificial activity, misleading terms, or incentives designed to influence rankings, reviews, or reported engagement rather than attract genuine players.
A historical study of incentivized advertising, based on one million impressions and quasi-experimental analyses, found lower click-through rates but a higher overall install rate for the advertised app in its dataset. It also found that reward value and time to receipt affected the incentive mechanism. The study addresses rewarded advertising, not every modern reward-based UA model; its finding is best read as a possible funnel trade-off, not a current benchmark for campaign performance.
Are rewarded installs allowed?
A legitimate exchange—clearly offering a reward for a genuine player to try a game and complete a stated task—is different in intent from buying artificial installs or activity to manipulate rankings, reviews, or engagement measures. The distinction does not by itself settle whether a specific campaign complies with store rules. A 2020 study identified historical policy and trust risks around incentivized activity, but it does not establish present-day enforcement or the current wording of store policies.
Before launching, check the current App Store Review Guidelines and Google Play policies for the campaign’s exact mechanics and the markets where it will run. Avoid offers that reward artificial engagement or obscure what the player must do. Clear terms and a genuine value exchange support a better player experience, but they are not a substitute for checking applicable rules.

Apple describes AdAttributionKit as a privacy-preserving framework that lets registered ad networks and developers attribute app installs and re-engagement through signed postbacks, without tracking people or devices across other companies’ apps. Apple says it supports multiple ad formats and campaign measurement. Confirm that the network you use is registered and integrated with the framework.
Attribution is not a complete record of every campaign interaction. Apple says click-through attribution is based on the most recently tapped qualifying ad when the advertised app launches; if no qualifying ad was tapped, the most recently displayed ad may receive attribution. Conversion values and publisher identifiers depend on privacy thresholds, and the information available varies with crowd-anonymity tiers. A null or missing field therefore does not prove that a campaign had no value.
Apple says AdAttributionKit can be used for its privacy-preserving attribution purpose without an AppTrackingTransparency (ATT) prompt. That does not remove other obligations: apps that track users or access the device advertising identifier must obtain permission through ATT, and using AdAttributionKit alone does not settle every consent, disclosure, or privacy requirement. Apple Ads announced on April 10, 2025, that it had registered with AdAttributionKit and described AdServices as complementary attribution information for Apple Ads campaigns. That is a dated platform update, not a guarantee about every current implementation or version.
What makes an offer or ad experience trustworthy?
Google’s August 2026 guidance on mobile-game ad quality emphasizes predictable behavior, user control, and a fair exchange of value. It warns against forced redirects and deceptive placements, and describes meaningful in-game rewards as a positive exchange. In practical terms, a player should understand what is being offered and what will happen when they accept.
Quick Recap
- State the reward, task, eligibility, timing, and completion conditions plainly.
- Do not disguise an ad or make a tap appear to do something it does not.
- Keep redirects and other behavior predictable, with a clear way for the player to retain control.
- Check what happens after the reward is earned: whether players continue voluntarily and whether the experience supports the game they came to play.
