The 2025 AppsFlyer Performance Index has been released, and Gamelight, the leading rewarded UA platform, has once again demonstrated its strength as a top mobile marketing partner. This year’s results highlight Gamelight as one of the top-performing user acquisition sources across the entire Index, delivering both quality and scale for mobile game publishers worldwide.
Exceptional Performance in the New AppsFlyer Performance Index
This year’s Performance Index recognises Gamelight across every major dimension of the ranking structure, reflecting balanced strength on a global level and within specific regions and gaming categories.
Global Rankings Gamelight is ranked among the top UA sources in the Global ranking, reaffirming its position as one of the strongest performers in the entire Index.
Regional Rankings Across North America, EMEA, and APAC, Gamelight secured top placements, demonstrating consistent performance worldwide and strong competitiveness in each major region.
Gaming Category Rankings Gamelight also ranked highly in the overall Gaming Index, showcasing its effectiveness as a leading partner for game publishers across platforms.
Genre-Specific Rankings Within individual gaming genres, including Casual, Hypercasual, Casino, Mid-core, and Match, Gamelight achieved leading positions, underlining its versatility across different verticals.
Notably, Gamelight is one of the few platforms ranking highly on both the Power and Volume indexes, demonstrating its ability to combine high-quality users with meaningful scale on both Android and iOS.
These achievements emphasise Gamelight’s position as one of the strongest and most competitive UA channels in today’s mobile advertising ecosystem.
Consistent Momentum Across Previous Editions
The AppsFlyer Performance Index is considered one of the most recognised benchmarks in mobile advertising. Likewise, Gamelight has been consistently ranked among the top-performing platforms, particularly in the rewarded category.
Past rankings reflected:
- Top-three placements in multiple categories
- #1 rewarded UA source globally
- Top-two rankings across key verticals and geos, including Casual gaming in Western Europe, Japan, and South Korea
This steady trajectory highlights Gamelight’s sustained growth and its evolution into a leading global marketing partner for mobile publishers.
Setting the Standard for Rewarded UA
Gamelight has played a central role in elevating rewarded UA from a secondary channel to a core acquisition strategy for game publishers. Powered by advanced optimisation and a data-driven recommendation engine, Gamelight’s rewarded UA model focuses on delivering high-intent, engaged users who convert into long-term players.
This approach has:
- Improved retention and engagement
- Increased ROAS stability across platforms
- Enabled global publishers to scale profitably in competitive markets
Gamelight’s continued performance in the AppsFlyer Performance Index reinforces how far it has driven the rewarded UA category, and how effectively rewarded traffic can compete with the industry’s largest UA channels.
These results line up with another major recognition from earlier this year. In the Singular ROI Index 2025, Gamelight was named a top ROI-driving channel, placing in 15 of 21 categories and ranking as the #1 rewarded UA source globally.
Case Study: Delivering Profitable Global Scale for Unico Studio
Gamelight’s strong placement in the Performance Index is backed by measurable results. Unico Studio, one of the largest casual gaming publishers globally, partnered with Gamelight to scale 16 puzzle titles across Gamelight’s 13 geos on iOS and Android. The lineup included Bus Craze, Wood Block Jam, Brain Test: All Star, and additional puzzle hits.
- Strong performance: Bus Craze exceeded both profitability targets, outperforming the D7 ROAS goal of 70% and surpassing the D30 ROAS target of 110%.
- Full-funnel optimisation: With 40 shared in-app events, the campaign benefited from precise optimisation across IAP and ad revenue.
- Improved data quality: Shared suppression lists enhanced postback ratios and signal clarity.
- Efficient execution: Close collaboration allowed rapid iteration and fast scaling across all geos.
- The result was profitable global growth, reinforcing Gamelight’s ability to deliver ROAS-positive scale for top-tier studios.
