Rewarded video ads: when they help and when they hurt

Hybrid monetisation — in-app purchases combined with rewarded video ads — is the dominant model in 2026. The advertising side of that pairing is genuinely attractive: rewarded ads are opt-in, well-tolerated, and generate revenue from the broad base of free players who would never have spent on a purchase. For most studios, turning them on adds a real revenue line within days.

What turning them on can also do, quietly, is reduce the revenue line that was already working. Rewarded video and in-app purchases overlap in what they offer the player — both deliver value in exchange for something the player gives up. When the ad-based path is too generous or too available, a meaningful share of the players who would have paid for the same value learn they don't need to.

The skill isn't in deciding whether to run rewarded ads. It's in deciding where to put them and what they should hand out.

What rewarded ads are actually substituting for

A rewarded ad is, from the player's point of view, a transaction. They give thirty seconds of attention and receive an in-game reward in return. That reward has a value, and the value is set by whatever else in the game costs that same reward.

If the same reward is sold in your store for $0.99, the rewarded ad is now functioning as a $0.99 substitute that costs the player nothing but time. For players whose alternative was to buy that item, the ad has eliminated the reason to buy. For players whose alternative was to skip the item entirely, the ad has handed them value they wouldn't have generated otherwise.

The first group is your existing paying base. The second group is your free base. Rewarded video ads grow revenue when they convert free players into ad-watchers and shrink revenue when they convert paying players into ad-watchers. The same ad placement can do either, and which one it does depends on the design choice you may not realise you're making.

The cannibalisation pattern

The cleanest sign of cannibalisation is when adding rewarded ads to a game produces a lift in ad revenue but a quiet decline in IAP revenue from the same player base. The total often goes up — but less than the ad number alone would suggest, because part of the ad revenue came from purchases that no longer happened.

This pattern shows up most strongly when rewarded ads are placed at or near the moments where players would otherwise consider a purchase. The "out of energy" moment, the "extra life" moment, the "extra spin" moment — these are all friction points where the game was previously asking for money. Putting a rewarded ad at those exact points moves the player to the ad path because it's cheaper than the IAP path.

Players who genuinely don't spend won't be lost on either side — they take the ad. But players who were paying and now see a free alternative will quietly migrate. The migration is hard to spot on aggregate revenue dashboards because both numbers exist. What you have to track is per-player behaviour — did the players who were spending continue to spend after the ad placement went live, or did their spend rate drop?

If the spend rate of your paying base declines when rewarded ads launch, the ads are extracting value from the players you were already monetising rather than from the players you weren't.

Where rewarded ads strengthen the economy

The placements where rewarded ads add revenue rather than substituting for it have a specific shape. The reward they grant has to be something the player wouldn't have bought.

A rewarded ad that grants a small amount of an abundant currency at a moment of mild friction adds value without competing with any purchase. A rewarded ad that doubles a reward the player already earned — turning a single-coin payout into a double-coin payout — feels like a bonus rather than a substitute. A rewarded ad that's offered after a successful run, not after a failed one, captures the player at a moment of satisfaction rather than at a moment of friction where they might have paid to remove that friction.

The pattern across these is that the ad is positioned alongside the regular game loop, not in place of a moment that would have produced revenue. It captures attention from players who were going to keep playing anyway and converts it into ad impressions. That's net new revenue, not redirected revenue.

Rewarded ads also work as a top-of-funnel acquisition tool for paying behaviour. A player who has watched a few rewarded ads has demonstrated they're willing to engage with the game beyond passive play. That engagement signal can be useful when deciding which players are worth showing a purchase offer to — ad watchers convert at higher rates than ad refusers, on average.

How to gate ads without making the game feel adverse

The instinct when cannibalisation appears is to limit rewarded ads — cap them at three per session, remove them from key friction points, require them to be unlocked. Some of this is necessary. But heavy-handed gating can make the ads feel like a privilege the game is doling out reluctantly, which damages player perception of what was previously a player-friendly feature.

The better gating is design-level. Decide what rewarded ads can grant and what they can't — and keep that line consistent across the game. If rewarded ads can grant soft currency but not premium currency, players learn the rule and stop expecting ads to replace purchases. If rewarded ads can grant cosmetic items but not progression-critical ones, the IAP path keeps its purpose.

Position matters as much as caps. A rewarded ad offered at the moment a player is celebrating a win lands differently than one offered at the moment they hit a wall. The first reads as a reward; the second reads as a relief valve that's competing with the purchase you were about to show.

The clearest rule is to keep rewarded ads aligned with what free play already offered. They should accelerate, not replace. They should reward engagement, not solve frustration. Frustration is what your purchases are for.

Measuring the right thing

The metric that matters when you're evaluating rewarded ads isn't ad revenue. It's total per-player revenue from the segment that was paying before ads launched.

If a paying segment's total revenue (IAP plus ads) holds or grows after ad placements go live, the ads are additive. If their IAP revenue drops by more than their ad revenue gained, the ads are subtractive — they've extracted less value than they removed.

The same comparison run on the free segment usually shows pure addition, because there was no IAP revenue to substitute for. Aggregating these two segments together hides the dynamic. Separating them — paying segment vs free segment, before and after rewarded ads — surfaces it.

Hybrid monetisation works when each channel does something the other doesn't. Rewarded video ads earn revenue from players who would never have spent. IAP earns revenue from players who would. The trouble starts when you let the two channels compete for the same player at the same moment — at which point the cheaper path wins, and you end up with the same revenue you had before, distributed across more friction.
