How it works

Rewarded ads align incentives

Rewarded video ads are the most player-friendly format: the user opts in to watch a 15–30 second ad in exchange for a defined reward. Subway Surfers integrates rewarded ads across more surfaces than any other app in this library, with ad watching offered as a direct substitute for currency payment. Capybara Go! ties ads to energy acquisition, making ad watching part of the core session rhythm.

Core principle

Rewarded ads align incentives. The user gets something, the developer gets revenue, and the session continues. Interstitials extract value without offering any.

Watch out for

Ad frequency is the primary driver of uninstall in ad-supported apps. Interstitials shown more than once per session dramatically increase churn.

How they use it

Rewarded video ads are integrated as an energy acquisition method. Players can watch ads to receive 15 energy per watch, up to twice daily. Additional placements: watching three ads substitutes for 300 gems to hatch one pet egg batch. The Adventure Supply Crate can be opened by watching three ads (twice daily) in addition to its 80-gem paid option. A permanent 'ad-free card' upsell appears on every rewarded video, converting each ad interaction into a subscription awareness moment.

Why it works

Rewarded ads function as an energy source within the core economy rather than as an interruption between sessions. Each ad watch moves the player closer to the next run. The persistent ad-free card upsell turns every ad interaction into a conversion touchpoint for the premium subscription.

The detail

Ad placements appear at each spend point as an alternative to gem payment. The ad-free card upsell appears as a persistent overlay on the ad viewing confirmation screen.

Takeaway

Rewarded ads provide 15 energy per watch (twice daily), integrated directly into the resource economy rather than offered as a separate bonus.

How they use it

Watching a rewarded video is one of the four daily tasks, with completion contributing to the full daily bundle of 3M FC coins, 300 gems, 300 Star Pass Credits, and 750 XP. An offerwall under Extra Time ('earn gems, complete offer') provides small gem payouts for completing external actions, downloading games, completing web quizzes (61 gems for a 1-minute quiz). Individual daily tasks can be swapped for 10 gems, including the ad task. The league quest system includes an 'Ad veteran' collaborative quest where ad views count toward the league's shared target.

Why it works

The offerwall routes players to third-party games and websites in exchange for small gem amounts, functioning as an embedded acquisition tool for other titles rather than standard rewarded video. The 'Ad veteran' league quest integrates advertising engagement into social obligation, watching ads contributes to the league's collective goal, framing ad viewing as a contribution to the group rather than a personal choice.

The detail

The ad task appears as a card in the daily tasks list with a dedicated Watch button. The offerwall opens in a separate webview labeled 'earn gems complete offer.' The league quest system surfaces the 'Ad veteran' collective goal within the league hub.

Takeaway

The 'Ad veteran' league quest makes ad watching a social obligation, ad views count toward the league's collective target, framing the behaviour as contributing to the group rather than as personal monetization.

How they use it

Rewarded and interstitial ads appear across more surfaces than in most apps in the library. Rewarded placements: daily reward doubling (watch to convert 16 coins to 32), two free diamonds per day from the hamburger menu, the salesman character (a recurring city resident who asks for help and delivers diamonds with a personalized voiced story), and building merges (three free ad-watch merges per day, alternative is 50 coins each). Interstitials appeared mid-browse of the store and after completing a citizen classified quest, without user action and with no reward. Any in-app purchase permanently removes interstitials; rewarded ads remain available.

Why it works

The salesman is the most narratively integrated ad placement in the library. Watching an ad triggers a voiced character interaction: the salesman thanks the user by name, references a personal story (grandma found diamonds in the backyard, he's giving them to his best friend), and hands over diamonds with a handoff framing. The ad is not presented as "watch this ad", it is presented as "help the salesman," making ad watching an act of in-game civic virtue. The 1,000-watch achievement track turns what would be an abstract ad metric into a character relationship the user is the mayor managing.

The detail

The salesman character is visible on the city map with an ad bubble above his head and voiced dialogue. The daily diamond ad button is in the hamburger menu. The daily reward doubling button appears on the daily reward popup. The merge ad option appears on the merge confirmation screen. The hamburger menu newspaper section contains an additional ad banner for free diamonds.

Takeaway

The salesman character is the only rewarded ad placement in the library that creates a recurring named character relationship around the ad-watching action, the user is not watching an ad, they are helping their city's overworked salesman.

How they use it

Rewarded video ads appear across more surfaces in Subway Surfers than in any other app in this library. Home screen: post-run prize popup (1,000 coins, watch ad to double to 2,000), persistent 500-coin banner, three-key reward banner, and a 'Coins Galore' exclusive deal (watch 3 ads for 20,000 coins, 7-hour 48-minute countdown). Store: daily gift, token box, three blue keys, hoverboard (300 coins or ad), score booster, head start. Daily rewards: five daily reward slots each requiring an ad, no free daily reward on this screen. Missions: complete by playing or skip by watching an ad.

Why it works

The ad ticket product inverts the typical rewarded ad model: players pay to receive ad rewards without watching. Any purchase removes pop-up interstitial ads permanently and unlocks Boombot, structuring the entire forced-ad experience as a paywall where any payment eliminates it.

The detail

Rewarded ads are positioned side-by-side with currency costs at every major spending point. The Mystery Box Mania event aggregates ad watches across the session toward a 10-watch reward milestone. The ad ticket system (ad bypass) sells instant rewards without watching, $2.99 for 10, $4.99 for 25, $9.99 for 60 tickets.

Takeaway

Ad watching is offered as an alternative to gameplay completion for missions, watching an ad skips the jump-15-times mission entirely, making ads equivalent in value to actual play.
