Case Study: Etermax doubles Trivia Crack conversion with Vungle Creative Labs' interactive end cards

Trivia Crack Doubles Conversion with Interactive End Cards

Argentinian studio Etermax’s Trivia Crack — already a viral, top‑downloaded game — needed a way to capture its personality and social gameplay in very short ads to keep attracting new users. The challenge was to convey core features and the game’s addictive, shareable experience in 15–30 seconds while creating an engaging format that actually drove installs.

Vungle Creative Labs produced 15‑ and 30‑second videos paired with interactive end cards that let users spin a topic wheel and answer a sample trivia question before downloading. The interactive end cards significantly outperformed static ones: the 30‑second interactive combo more than doubled conversion (~112% lift) and the 15‑second interactive ads improved conversions by 33%, driving a wave of high‑quality installs with retention often higher than organic users.
