Overview
What I built
MercaPrecios is a web price-guessing game designed for solo sessions or games with friends. Each round shows a real Mercadona product and players estimate its price before the timer runs out. The game supports rooms shared by link, code or QR, category selection and different scoring modes. Its product catalogue is updated automatically, and the mobile-first experience uses real-time communication with a polling fallback.
