Pi Day UX Challenge 2025
This is your chance to showcase your prototyping skills, push the boundaries of interactive high-prototyping, and win cool tech merch.


What is Pi Day, and Why Does it Matter?
Pi Day, celebrated on March 14th each year by math enthusiasts, scientists, and creatives alike, is a nod to the mathematical constant π (pi), which starts at 3.14 and continues infinitely.
At ProtoPie, Pi Day is more than a celebration of numbers; it’s a tribute to innovation, creativity, and limitless possibilities. Much like how prototyping allows designers to explore, iterate, and refine ideas without limits.
Think fast, prototype smart, and push the boundaries of UX design within the spirit of Pi Day!
The Challenge
Create a high-fidelity prototype that’s within 3.14 seconds in interaction time. Use ProtoPie’s advanced features to create a seamless and dynamic interaction. Your prototype can be any level of fidelity, but high-fidelity prototypes will be scored higher. We encourage you to use the following topics and features:
- Math-inspired: Explore mathematical concepts, visualize Pi as a symbol, or delve into its limitless nature.
- Creative and innovative: Think outside the box and surprise us with your unique interpretation of Pi Day.
- Advanced features like:
- Conditional logic for dynamic behaviors.
- Loop interactions for smooth, continuous flows.
- Chained interactions for realistic, multi-step experiences.
