Interactive Mobile Raffle
Gamified Mobile Raffle That Accelerated Broker Plus App Adoption
I designed a gamified mobile raffle that helped Broker Plus acquire over 3,000 new users in just three weeks, transforming a conference activation into a high-conversion growth channel.
My role: Defined the user flow and interaction model for the raffle experience. Collaborated with Product and Engineering Team to align on business goals, prize logic, and technical feasibility. Considered emotional design: color schemes, animations, and feedback to maximize delight and clarity.
Problem & Opportunity
Problem:
The Broker Plus app existed, but user acquisition around conference events was limited.
Many users were hesitant to register or download the app just to “check it out” at an event.
Without a compelling reason to install, the app was under-utilized as a marketing touchpoint.
Opportunity:
Use a gamified raffle experience to make app installation more attractive.
Let attendees engage without friction: no mandatory registration required.
Use push notifications to deliver instant win / loss feedback and drive repeat engagement.


Research & Insights
User interviews: Interviewed stakeholders and talked to a small group of brokers about what would encourage them to download an app. Many said “free stuff,” “games,” or “quick wins” are very compelling at events.
Competitive benchmarking: Looked at other event apps that run lotteries or raffles to understand how they handle onboarding and prize delivery.
Key Insights:
Users are more likely to install when there is no barrier (no forced signup) up front.
Instant feedback (win / loss) is emotionally engaging and drives viral sharing.
Using color and motion for “win” state (e.g., celebratory color) vs “lose” state increases emotional impact.


Ideation & Design Process
High-Fidelity Design:
Built mockups with branded colors, playful rewards UI, and visual hierarchy to highlight prize vs “play again.”
Designed 3-4 distinct UI states; idle, reveal in progress, win/loss
Applied micro-animations or feedback states: e.g., a confetti burst on win, subtle change of color/texture on loss.
Emotion & Visual Design:
Chose a bright, warm secondary color for “win” states to evoke joy.
Used a more neutral tone when user loses, but still kept it visually clean to avoid feeling punitive.


Implementation & Collaboration
Worked with mobile developers to ensure the “scratch” interaction was technically feasible (using a simple tap or swipe to reveal).
Defined lightweight notification content with Product Manager: “Congrats! You won! Check your prize,” or “Sorry, not a winner this time — try again.”
Provided design specs and assets (icons, buttons, gradients) for dev.


Outcome & Impact
Results and User Feedback
After release, the raffle experience drove over 3,000+ app downloads in three weeks.
This represents a significant uplift in app adoption tied directly to the conference.
Many users reported the raffle was “fun” and “easy to play,” especially because they didn’t need to register first.
Stakeholders also noted increased booth traffic / app engagement post-conference.
Reflections & Learnings
Nothing is perfect — there are always opportunities to improve.




Challenges
Without requiring registration, it’s harder to convert these users into long-term, active brokers.
Business requirements and objectives were not clear at the beginning and required re-work multiple times.
What went well
Low barrier to entry (no registration) meant more users tried it.
Emotional design (color, reveal interaction) made the experience enjoyable.
Close alignment with product and dev ensured a smooth, timely launch — perfect for a conference window.
