The Challenge of Sustaining a Mature Mobile Franchise

Angry Birds 2 is part of one of mobile gaming's most enduring franchises. Sustaining growth for a major title at this stage requires more than maintaining brand recognition. It requires precision acquisition of high-value users on iOS, re-engagement of lapsed players on Android, and a DSP partner capable of scaling spend without sacrificing ROI. That's a high bar. RZR cleared it.

The Goal:
Scale iOS user acquisition and Android retargeting performance for Angry Birds 2 globally, while holding strict D7 ROI targets

“RZR has become one of our most trusted performance partners for Angry Birds 2. From iOS user acquisition to Android retargeting, they've consistently exceeded our targets and expanded the scope of what we're doing together. The 10x growth in spend over the past year reflects the confidence we have in their ability to deliver.”

Martin Boccardi, Senior Performance Marketing Manager, Rovio

From Android Retargeting to #1 iOS UA Partner

Rovio started with Android retargeting. Strong performance on that foundation opened the door to iOS user acquisition. Within one year, both products were scaling together, with RZR achieving the #1 partner position on iOS for UA and a top 5 partner position on Android for retargeting.

Play 1: Android Retargeting Foundation

Target:  Re-engage lapsed Angry Birds 2 players, with custom strategies for paying users (Spenders) and non-paying users (Non-Spenders).

Execution highlights:
Consistent on-target D7 ROI performance across geos on a monthly basis
Campaign-level gains driven by model refinements and continuous publisher-level optimization

Despite operating retargeting campaigns exclusively, RZR’s Android performance placed them in the top 5 Rovio partners by spend.

Play 2: iOS User Acquisition

Target: Acquire high-LTV users for Angry Birds 2 across geos, with consistent performance against D7 ROI targets.
Execution highlights:

Launched August 2025; scaled to #1 iOS partner in under 4 months
Deep neural network (DNN) model upgrade deployed, incorporating non-attributed data specific to the App Store ID for more accurate impression valuation
Separate prediction layers based on click behavior, enabling more comprehensive prediction of installs and down-funnel behavior.
Win rate model improvements drove higher quality bids at exchange level


From One Market to Many
RZR's iOS UA scale didn't happen all at once. It was built market by market.


A multi-market campaign spanning geos established the foundation. With consistent above-target D7 ROI performance, the model accumulated app-level learnings that transferred directly into new geographies. Weekly spend grew more than 4x over the course of Q1, with D7 ROI holding above benchmark throughout.
With that foundation in place, the strategy sharpened. RZR moved from a single international campaign to three geo-specific campaigns targeting high-priority markets across Europe, Latin America, the Middle East, and APAC — with the model dynamically allocating spend toward the highest-performing countries in each cluster.

The Results
D7 ROI reached an average 6.5% above goal for the majority of Q1.
What Drove the Win

Deep Neural Network Architecture

The DNN model upgrade was the performance engine behind iOS UA scale. By incorporating non-attributed data by App Store ID and separating prediction based on click behavior, the model built a more accurate picture of user value at the impression level. Bid quality improved. Win rates improved. ROI followed.

Weekly Optimization Rigor

Scaling while maintaining ROI targets requires constant refinement. RZR’s team ran weekly publisher and exchange-level optimizations, adjusted bids by country and user segment, and deployed parallel model tests to keep performance on target as spend grew.

LTV-Driven Segmentation

Rebuilt audience strategy across geo, creative, and supply-path cuts to isolate profitable cohorts

Expanding Format Roadmap

New banner creatives, playable formats, and native ad tests are in active planning for both iOS and Android, building toward additional scale in the next campaign phase.

Why This Isn't Just a UA Success Story

RZR built a performance foundation that has expanded with every campaign phase:

DNN model precision impression-level valuation that improves as data compounds

LTV-based segmentation custom retargeting strategy built around spend behavior

Multi-product trust Android retargeting success supported iOS user acquisition, which is now supporting CTV expansion

Weekly optimization discipline exchange and publisher-level refinements kept ROI above target at every spend level

Long-term partnership one strong product became the case for the next

"RZR has a considerable edge in global traffic cover and advanced mobile advertising technology, but what is even more striking is that its skilled and dedicated service team has supported DHgate in exploring high-value extra channels in a short amount of time."

Ella Yang, VP @DHgate

Case Study

"On iOS, almost all our players opt out of tracking, so retargeting is genuinely hard. RZR made it work anyway. Their probabilistic approach re-engaged our players without device identifiers and kept our D7 and D30 ROAS above target month after month, at a cost per install inside our KPI."

Masha Astapkovich, Head of UA, Highcore Games

Case Study

"RZR's team demonstrated outstanding expertise across every dimension of retargeting — from audience segmentation and model iteration to campaign pacing around our monthly in-game events. They consistently exceeded our KPI targets over the long term and have become our most trusted retargeting partner on Android."

Their commitment to data-driven optimization makes them an invaluable partner in driving sustained growth.

Marie Kim, User Acquisition - Team Lead @ Bagelcode

Case Study

On iOS UA, RZR earned their way to the top of our stack, outperforming other partners as we scaled spend and tightened our D7 ROAS targets. That track record is why we launched iOS retargeting, which we awarded to them exclusively: a privacy-safe, probabilistic pathway to win our lapsed players back at scale.
