Project Background
Background
In Taiwan, every receipt (called an invoice in Taiwan) you get from a store is also a government-issued lottery ticket. Every two months, the government draws the winning numbers from the Uniform Invoice Lottery.
The Invoice Manager App serves as a digital carrier, allowing users to store invoices via a mobile barcode. It automates the entire process—from organizing digital records to auto-matching winning numbers.
The Product Team’s Goal
Optimize the Consolation Prize’s winning experience, and lead users to open bank accounts to receive the award.

The Prize Wheel Experience
We replaced a static consolation banner with an interactive prize wheel. Leveraging Variable Ratio Reinforcement, we used the unpredictability of lucky draws to drive conversions among users who previously ignored fixed rewards.
Designing the Details
I used a ”comic strip” layout to explain the consolation prize was given to users who did not receive the Uniform Invoice Lottery.
Final Outcome
Lastly, I added fade-in animations to guide users through understanding the storyboard.
Key Results
High conversion rates
The original goal was to bring 3,000 new users to our client, Pocket Securities. We successfully created 7,000+ conversions, exceeding our clients expectations by 200%.

Scalable Design Template
More than just a one-time campaign, the comic strip became a UI design template for the following events. Any graphic designer on the team can easily follow the pattern and customize the style.
Moreover, the consolation prize became a signature feature of the app, attracting clients to collaborate with our business unit, bringing additional profits.
