Interactive scratch quiz – through playful curiosity
Mercedes-Benz needed to spark conversations at trade shows and generate quality leads. Through a scratch-to-reveal iPad quiz with gamification, smooth flows, and delayed registration, we nearly doubled lead conversion while creating effortless engagement. The tool later scaled as eyeQuiz across multiple major brands.
Core shift: From sales pitch to shared experience – through playful interaction.

How we solved problems
Three challenges, three breakthroughs
Trade show booths don't need forms. They need conversation starters.
The brief said «lead capture tool.» Reality said «nobody wants to fill out forms.» We interviewed hosts and visitors. Discovered the tension: visitors want privacy and speed, hosts want conversations and contacts. We built a scratch-to-reveal quiz inspired by scratchcards. Physical. Satisfying. Curiosity-driven.
Result: almost 2× higher lead conversion. Play beats pitch. Always.
Registration kills momentum. Move it to the end.
The client wanted the registration form at the start. Full of fields. Right where curiosity dies. We challenged it. Ran workshops. Let users experience the flow. They scratched. They smiled. They wanted to play. Moving registration to the end changed everything. Frictionless start. Higher finish rate. Natural conversations. Sometimes the most powerful feature is knowing what to remove.
Public spectacle drives engagement. Privacy preserves trust.
We mirrored the quiz to Apple TV. Big screen. Shared excitement. Bystanders drawn in like moths to light. But we split visual layers – the game stayed public, contact details stayed private. Built smart. Felt simple. The quiz became a bridge between curiosity and conversion – and later scaled across multiple brands as eyeQuiz.
Final Designs
A co-created experience in action
In 2015, I hacked the game shoulder-to-shoulder with Gerd; today, we can hack with Geminin. The same? Nope.

Gameplay
Some Shots of the gameplay
During the initial moments of the scratching game, players can choose to stop when they believe they've identified the Benz. However, the clock continues to run regardless.
Instant feedback after the participant answered the question, "What Benz is it?"

Key Learnings
What this project taught me
Co-creation unlocks what pitch decks cannot
The client wanted the registration form at the start. We had wireframes proving otherwise. The pain: arguing with spreadsheets. What worked: inviting real users into a workshop and letting the experience speak for itself. Suddenly, moving the form made sense.
Mechanics kills emotion. Animation revives it.
Scratching images felt slow. The pain: mechanical logic worked, but emotional impact died. What saved it: combining animation techniques, asynchronous loading, and refined mechanics. Performance + polish = extraordinary experience. UX goes far beyond visual.
Design thinking means designing for both sides of the interaction
Visitors want privacy and speed. Hosts want conversations and efficiency. We interviewed both. The pain: conflicting needs. What helped: mapping dual motivations early and designing the system around the shared moment – not just the form.
Why this still matters
Attention is earned, not captured
Trade shows are noisy. Forms are friction. The brands that win don't demand attention – they design moments worth sharing. Curiosity beats coercion. Play beats pitch. This quiz later became eyeQuiz, scaled across multiple major brands, proving one truth: people don't resist experiences. They resist being sold to.
