Sixty percent of top-grossing mobile games run rewarded ads. Players who engage with them are 4x more likely to make a purchase. Completion rates sit above 90%. So, studios should treat rewarded ads not as a set-it-and-forget-it checkbox rather as a real monetization machine. In this post, we break down how they actually work, where they perform best, and how rewarded UA fits into the growth picture.
What Are Rewarded Ads?
Rewarded ads are opt-in placements where a player voluntarily watches a video (typically 15 to 30 seconds) or completes a small interactive task in exchange for an in-game reward. Extra lives, virtual currency, a power-up, a spin. The key word is opt-in. Unlike banners or interstitials that interrupt gameplay, rewarded ads put the player in control.
That single distinction drives everything. The player chooses to engage. They finish the ad (completion rates regularly exceed 90%). They get something tangible. The developer earns a premium eCPM for a genuinely attentive impression. The advertiser gets a viewer who actually watched. Everyone walks away with something.
Common Reward Types
Research from Unity’s Mobile Growth and Monetization Report breaks down which rewards drive the most engagement:
- Gacha / virtual lottery pulls (31.1%): Randomized rewards create curiosity and keep players coming back
- In-game currency: Simple, reliable, works across almost every genre
- Extra lives or continues: The classic placement in level-based casual games
- Time-limited power-ups: Popular in mid-core titles because they let players experience premium mechanics without paying
- Unlocking content: Chapters, skins, or game modes
Reward design matters more than most studios realize. Tying the reward to a player’s current pain point, like losing a level or being one resource short of an upgrade, dramatically increases opt-in rate. The closer the reward is to what the player actually needs in that moment, the more it converts.
The Data: Why Rewarded Ads Dominate
Before getting into implementation, it’s worth grounding this in actual numbers, because they’re pretty striking.
Player sentiment is overwhelmingly positive:
9 in 10 players actively interact with a rewarded ad to claim a reward, and 85% say they enjoy the in-game rewards these ads deliver. Nearly half of US marketers (46.3%) report that rewarded ads make players feel more in control. That’s a sentiment that’s basically unheard of for any other ad format.
The monetization uplift is real:
Players who engage with rewarded ads are 4x more likely to make in-app purchases compared to those who don’t. Some sources report that rewarded video can multiply IAP revenue by up to 6x by letting non-paying users experience premium content they might eventually pay for directly.
Retention effects are significant:
Users who engage with rewarded ads show up to 3.5x higher retention compared to those who don’t. This makes intuitive sense: players who are motivated enough to watch an ad for a reward are more invested in the game to begin with.
Market adoption:
Around 60% of top-grossing mobile games now integrate rewarded ad formats. Across casual titles, rewarded ads account for 45% of ad revenue, making them the single largest contributing format in that segment.
Genre Fit and Placement Strategy
Not all game genres benefit equally from rewarded ads, and not all placements within a game are created equal. Getting this right is less about following a universal template and more about understanding where your players are emotionally at any given moment in the session.
Hyper-casual games live and die by volume. Retention windows are short, player investment is low, and the economy is simple. Rewarded ads work well here but they need to be immediate and contextually obvious. The most effective placements are tied directly to failure moments: a continue button after a run ends, or a score multiplier at the start of a session.
The reward needs to be self-explanatory because hyper-casual players are not reading anything carefully. Be specific about what the player will get. Vague mystery rewards don’t perform as well as clear messaging like “Watch a video for another life” or “Play a video for double coins.”
Casual and mid-core games (puzzle, match-3, RPG-lite) are where rewarded ads tend to perform best. Players have invested enough time and emotional energy to genuinely care about the reward on offer, but the game isn’t so hardcore that any hint of an ad feels out of place.
This is also where hybrid monetization really earns its reputation. Users who interact with rewarded ads during the first-time user experience are five times more likely to convert via in-app purchases later. Think of rewarded ads in this context as a try-before-you-buy layer: they let players experience what having premium resources actually feels like, which builds the desire to get more.
In these genres, you also have more room to be creative with placement. Rewarded ads don’t have to only appear at fail screens. They can sit in the shop as a daily free currency option, appear at the start of a hard level as an optional power-up, or show up in the game’s daily reward flow. Each of these is a different context with a different player mindset, and they can all perform well when the reward is relevant.
Where rewarded ads live inside the game matters as much as when they appear:
Unlike interstitials that get pushed at the player, rewarded ads are largely player-initiated. A “watch an ad for lives” button sitting at the fail screen isn’t forcing itself on anyone. The player sees it when they need it and ignores it when they don’t. Some developers even tailor ad experiences based on how players engage with ads. If they notice that certain players engage frequently with rewarded ads, they show them fewer interstitial ads. That kind of segmentation treats rewarded engagement as a signal about player type, not just a revenue event.
Placement triggers that tend to convert best:
- Immediately after a failed level attempt (“Watch an ad to continue”)
- Daily login bonuses (“Watch an ad for a bonus reward”)
- Shop placements (“Watch an ad for free currency”)
- Resource scarcity moments (“Watch an ad to get 50 more coins”)
- Pre-level power-up offers (“Boost your start, watch an ad”)
- Double reward prompts at the end of a successful run or session
That last one is underused. A player who just completed a level or had a good session is in a positive emotional state and more likely to engage voluntarily. Fail-screen placements get a lot of attention, but end-of-success placements can perform just as well with a lot less friction.
The Rewarded Ad / IAP Relationship
A common worry: will offering free rewards via ads cannibalize IAP revenue? The data says no. If anything, the opposite tends to happen. Non-paying users who engage with rewarded ads are 4x more likely to eventually make a purchase. Think of rewarded ads as a conversion funnel, not a substitute. They let players experience what it feels like to have premium resources, which creates demand for more.
The way to structure this in your economy: make the rewarded currency amount meaningful but not sufficient. Enough to feel valuable, not enough to replace the IAP-only tier.
Metrics That Actually Matter
Beyond surface-level eCPM, here are the metrics rewarded ad optimization actually runs on:
ARPDAU (Ad) is the core monetization health metric. It tells you the average ad revenue you’re generating per daily active user, and it’s the number that ties rewarded ad performance directly to your bottom line.
Rewarded Ad Engagement Rate is the percentage of your DAU who watch at least one rewarded ad per session. If this is low, either your placements aren’t visible enough or the rewards aren’t compelling enough.
Average Rewarded Ads Per DAU tells you how deep players are going into your ad economy per session. This should increase over time as your economy design matures.
Opt-in Rate is the percentage of players who tap “Watch Ad” when offered. Consistently below 30% is usually a signal that the reward isn’t landing, not that players don’t want ads.
Completion Rate should sit at 90% or above. Drops here typically point to technical issues or UX friction, not player disinterest.
eCPM by Network tells you which networks are winning auctions and at what price. This is your main lever for optimizing your mediation configuration over time.
Fill Rate is the percentage of ad requests that actually return a filled ad. Every unfilled request is revenue you didn’t earn.
Common Mistakes to Avoid
Showing rewarded ads too early in the session:
Players who haven’t formed any emotional connection with your game have no real reason to trade attention for a reward. The best placement triggers happen at moments of genuine desire or frustration, not arbitrary time intervals.
Setting static floors and never reviewing them:
Ad markets shift constantly. eCPM benchmarks change by season (Q4 premiums can be 30 to 50% higher than Q1), by geo, and by network competition. Review floor prices at least monthly.
Conflating short-term revenue with long-term player value:
A rewarded ad that bumps Day 1 revenue but increases churn by Day 30 is a net loss. Use incrementality testing and LTV cohort analysis to confirm your rewarded ad strategy is genuinely additive, not just moving revenue around.
Not segmenting rewarded users in your analytics:
Players who engage heavily with rewarded ads behave differently from non-engagers and from IAP spenders. Treat them as a distinct segment in your cohort analysis, live ops targeting, and push notification strategies.
Where Rewarded Ads Are Heading
A few trends worth keeping an eye on:
AI-driven personalization. Behavioral signals are increasingly being used to determine not just when to show a rewarded ad but what reward to offer a specific player in real time. This is moving from experiment to expectation across major mediation platforms.
Rewarded playables. Combining playable ad formats with rewarded incentive structures, like “play this mini-game to earn currency”, is gaining traction as a higher-engagement alternative to passive video. Early data points to stronger completion and conversion rates.
Integrated brand experiences. The Discord “quest bar” model, where branded content is embedded as a voluntary quest inside an app, points toward a future where rewarded ads are basically indistinguishable from live-ops events. Players opt into a brand challenge, earn in-game rewards, brands get real engagement.
UA Side: Using Rewarded Formats as a Growth Channel
Beyond rewarded ads, other rewarded models are now a channel in their own right, and the user quality they deliver tends to be measurably better than most alternatives.
Rewarded UA: What It Is
- Rewarded UA flips the model. Instead of showing players ads inside your game, you show ads for your game inside other apps, with players earning rewards in the host app for installing and engaging with your title.
- In a 2025 survey, 82% of mobile game developers said reward-based user acquisition outperformed traditional UA. Among those who had actually run a rewarded UA campaign, 95% reported gaining a competitive advantage, and 68% reported improved ROAS.
- Here’s how it works: users discover your game via an offerwall or rewarded placement in another app. They install and complete specific engagement milestones (reach level 10, spend 30 minutes, make a purchase). The host app rewards the user. You pay per quality action completed, not just per install.
- The key here is that you’re paying for behavior, not clicks. The economics align with your LTV models much more directly than standard CPI campaigns do.

Final Thoughts
Rewarded ads work because they’re built on a fair exchange. Players get something they actually want. Publishers earn premium eCPMs from genuinely attentive viewers. Advertisers reach users who completed the ad by choice. That kind of alignment is rare in advertising, and it’s why the format keeps outperforming everything around it.
Rewarded UA takes the same underlying mechanic and applies it to growth, giving you a way to acquire users who have already demonstrated real intent inside your game before you pay a cent.
The studios winning right now treat both as serious tools, not afterthoughts. The players are already opting in. Now it’s on you to make it worth their while.
