A lucky wheel spins on tablets
A mobile application distributes random prizes through smooth screen animations.
The project
The team developed a tablet-based contest mobile application for the Nespresso and Oatly retail activation managed by Magnetism. The in-store customer journey was designed to randomly distribute various prizes according to a precisely defined probability scale. The studio programmed an interactive touch-based wheel-of-fortune mechanic that handled draws in real time. The interface incorporates opening graphic drops and scaling effects to clearly display pictograms of the prizes won.

The challenge
Distributing physical prizes in-store requires absolute mathematical rigor. The application had to guarantee strict compliance with prize quotas through random draws, leaving no margin for error. The navigation needed to remain smooth and understandable at a glance to engage the public without requiring staff intervention.
Our approach
We developed a mobile application using React Native and Expo. The home screen features animated drops that encourage interaction. Users spin a wheel whose draw applies a strict probabilistic algorithm. To ensure reliable in-store validations, we configured the deployment to allow two distinct versions to coexist on each terminal.
