[Showoff] Shipped a free WC knockout Bracket Challenge in a week — 80 pts up for grabs, no signup wall, no penalty for wrong picks. Locks Sunday 7pm UTC. What I'd change.

This project is a free, no-signup World Cup knockout bracket challenge built in a week, designed for soccer fans who want a quick, low-friction prediction game without penalties for wrong picks. It’s interesting because it prioritizes user experience by removing common barriers like account creation and scoring penalties, while the creator openly shares what they’d improve, offering a transparent case study in rapid, user-focused productivity.
