Nubank World Cup Pool

In Brazil, during the World Cup, it is common for groups of people to get together and predict the winners of each match. This created an opportunity for Nubank to position its brand as a more social app.

This project was developed while I was working as a Senior Product Designer at Nubank.

As the designer responsible for Nubank’s first social feature, I was invited to work alongside another product designer on the company’s first fully social experience: the FIFA World Cup™ Pool.

Sketching

I started by sketching possible user flows. Since another designer would be working with me, I created different concepts that could serve as a foundation for the product’s final design.

Benchmarking

The Customer Experience team conducted a benchmark analysis of the main platforms offering prediction and betting services in Brazil.

Qualitative Testing

Once the prototype was ready, I worked with a UX researcher to test the flow in person with 12 participants. This was Nubank’s first in-person usability test after the pandemic. We identified several opportunities for improvement and iterated on the prototype over the following days.

Solution

We created an in-app betting experience that was neither complex nor required previous knowledge of football or betting.

At the first navigation level, users could create groups, see their position in the overall ranking, access their bets, and view relevant information about the World Cup.

Placing bets needed to be as effortless as possible, since there were a total of 64 matches. Most people only placed bets on the matches taking place that day.

Users had access to the overall ranking, which rewarded the winners with cash prizes. Therefore, the incentive to continue placing bets occurred four times a day, corresponding to the number of matches played each day.

At the first navigation level, users could create groups, see their position in the overall ranking, access their bets, and view relevant information about the World Cup.

Users were encouraged to play with friends and family. They could create as many private groups as they wanted and participate in multiple prediction pools.

Results

⭐ 8 million unique users making predictions

⭐ 298 million predictions across World Cup matches

⭐ Badges left as a positive legacy for future initiatives

⭐ Record user engagement on the bank’s platform

Guinnes Book

The project earned a Guinness World Records title by breaking the record for the largest number of participants in a prediction pool over a one-month period, with 7.3 million people.
