EIDOLON, a Cyprus-based game developer, specializes in creating engaging casual apps for global audiences. Their popular title, Happy Differences - Find them all, is a classic "spot-the-difference" game available on the Amazon Appstore. It's perfect for casual gamers seeking quick and enjoyable challenges.  

The Challenges

In a crowded casual gaming market, where user acquisition hinges on compelling ad creative, Eidolon struggled with ad creative fatigue. Repeating static visuals and generic ad formats led to diminishing user engagement—install rates plateaued, and ad spend ROI declined.

For a casual title that thrives on virality and shareability, dull creatives limit growth potential. In a market where over 70% of installs driven by ad performance, Eidolon needed a fresh, effective way to re-engage audiences and improve the ROAS (return on ad spend).

The Solution

Eidolon partnered with Mindworks to create a tailored playable ad for Happy Differences. Instead of static images, the team designed an interactive ad that mirrored the game's core “find-the-difference” gameplay, immersing viewers in the experience. Key features included:

• - Daily-life scene integration: Utilizing everyday life scenes to enhance relatability and user connection.
• - “Test Your IQ” gamification: A real-time IQ tracker motivated users with immediate feedback.
• - 20-second countdown: A timer to add excitement and a sense of urgency.
• - Guided onboarding: Subtle prompts to help users quickly grasp the experience.

Additionally, Mindworks implemented a performance-based billing model, charging based on actual ad spend rather than a flat fee, aligning costs with results.

The Results

The new playable ad delivered meaningful improvements. With fresh, engaging content, Eidolon overcame creative fatigue and reignited user interest.

The results speak for themselves:

• - A significant boost in app installs, driven by authentic gameplay and user engagement.
• - A performance-based billing model ensured every dollar spent aligned with actual results, improving cost efficiency and ROI. 

“Mindworks didn't just fix our creative slump—they turned our ads into mini-games that felt like the app itself. The Playable Ad's IQ tracker and countdown made viewers want to download, not just watch. Plus, paying based on actual ad spend meant we only invested in what worked. It's transformed how we think about user acquisition.”
