When it comes to mobile gaming, great gameplay isn’t enough. The ads need to stand out just as much as the game itself. For Fumb Games, the studio behind the hit title Bitcoin Miner, finding the right creative direction was key to driving growth. By using Quvy’s synthetic audiences and percentile scoring, the team identified their strongest ad concepts before launch, saving time, reducing risk, and improving creative quality across the board.
About Fumb Games
From humble beginnings to becoming one of the fastest-growing mobile studios in Europe, Fumb Games has millions of players worldwide. Founded in 2015 by two friends, Paul and Oscar, the studio grew from a $3,000 side project into a globally recognized name in mobile gaming, while retaining ownership.
With hits like Bitcoin Miner and Blocks of Bitcoin, Fumb Games has surpassed 20M downloads, over 1M monthly active users, and built a thriving Discord community of over 250K players. In 2025, the team secured $12M in UA financing backed by PvX Partners to fuel their next chapter of growth.
Synthetic Audiences for Mobile Gaming: Why Fumb Runs Ads Through Quvy
Instead of relying on benchmarking alone or creative intuition, Fumb uses Quvy as a creative intelligence layer to evaluate, refine, and validate new ad concepts before they go live.
Using Quvy, Fumb can:
- Instantly benchmark new ads against thousands of top global creatives
- Understand what exactly to simplify, or highlight
- Validate early concepts with real-time simulations before spending on UA
- Direct their UA budget toward only the creatives with proven predicted lift
This approach cuts waste, shortens creative cycles, and gives the team a data-backed way to test confidently at scale.
The Challenge
As Fumb Games scaled its user acquisition, maintaining ad creative performance became a priority. The team wanted a way to:
- Identify which new video and static ads would drive the most engagement before launch
- Reduce testing costs by understanding predicted performance early and focusing on assets with the strongest likelihood of success
- Benchmark creative quality objectively across their most important title, Bitcoin Miner
With multiple variations in production and a growing creative pipeline, guessing which ads would work best wasn’t sustainable. They needed a safe way to test each concept before spending on live campaigns, with data to support decisions.
The Solution: Testing with Quvy
Fumb Games partnered with Quvy to test both video and static ads for Bitcoin Miner across Instagram placements. Using Quvy’s Ad Simulation platform and percentile scoring system, the team could instantly see how each ad ranked for:
- Creative Rating – overall predicted creative strength
- Engagement Rating – percentile score for predicted audience response
- Estimated CPM, CTR, and CPC ratings – helping gauge efficiency and potential cost trade-offs
Instead of guessing which concepts deserved scale, Fumb used these simulations to validate creative ideas upfront, ensuring only the highest-potential ads moved forward.
Results
Quvy’s simulation revealed standout trends across both formats, with video emerging as the clear winner.
Video Ads
- The clear breakout performer was “Bitcoin Earning Game,” scoring a 77 Creative Rating with strong predicted CPM, CTR, and CPC metrics. This placed it at the top of the entire batch.
- The ad’s simple value messaging and strong gameplay visuals helped communicate trust and appeal quickly.
- Ads featuring real people on camera also scored well, reinforcing relatability in the “play and earn” niche.
Static Ads
Static creatives showed valuable directional insights, such as:
- Higher-vibrancy concepts with clear characters and coins tended to perform better.
- Simpler static layouts improved readability at a glance.
- Strong contrast and focused compositions helped lift predicted engagement.
Creative Insights
Across all tests, Quvy provided actionable creative intelligence to enhance clarity and focus:
- Simplify backgrounds
- Use a stronger contrast
- Highlight key objects (coins, characters, gameplay loops)
- Reduce text clutter
- Emphasize motion or expressive faces in video
These insights helped Fumb make quick, high-impact adjustments without wasting cycles on new shoots or redesigns.
The Impact
By using Quvy before launching campaigns, Fumb Games:
- Gained clear creative benchmarks to guide both internal design and agency partners
- Reduced wasted spend by focusing the budget only on top-performing ads
- Accelerated their creative decision-making cycle while maintaining quality at scale
“Quvy made it easy for us to test new ideas with confidence. Instead of guessing, we can see which ads have the strongest creative potential before they ever go live. It’s become an essential part of how we plan and validate our campaigns.”
— Paul West, CEO of Fumb Games
This process now acts as a creative safety net for new campaigns, allowing the team to avoid unnecessary spend and focus on the ads with the highest likelihood of success.
Key Takeaway
Fumb Games doesn’t just optimize ads; they use Quvy as a creative intelligence engine. By running their ad concept through Quvy before launch, they save time, reduce waste, and scale with greater confidence.
