Trivia Estadio Monumental
An interactive trivia platform purpose-built for live stadium events, enabling tens of thousands of fans to compete simultaneously from their phones, scored by both accuracy and speed of response.
1The Challenge
Live sports events are one-way broadcasts. The audience consumes the experience but doesn't participate in it — creating a passive attendance model that limits engagement, dwell time, and sponsorship monetization potential. Running a real-time, competitive game for 50,000 concurrent users inside a stadium (spotty WiFi, high-latency mobile networks, simultaneous requests) is an infrastructure and UX problem most event platforms haven't solved.
2The Solution
Led end-to-end product strategy, requirements definition, and delivery of a mobile-first trivia experience designed from the ground up for stadium constraints. Core design decisions included a speed-weighted scoring model that grades answers on a sliding time curve, rewarding both correctness and reaction speed to drive re-engagement round-over-round. A concurrency-first architecture was defined to handle simultaneous answer submissions at peak load without race conditions or score drift. Zero-friction UX required no app install — participants join via QR code or short URL with sub-5-second onboarding. A real-time leaderboard with live ranking updates visible on stadium screens creates social pressure that drives continuous participation.
