I Realized Mobile UX Isn’t Just “Desktop Shrunk Down” When I first worked on a casino and sportsbook interface, I assumed I could just adapt a desktop layout for smaller screens. That assumption didn’t last long. Users behaved differently. Completely differently. I noticed quick taps, short sessions, and very little patience for friction. What worked on a large screen felt cluttered and slow on mobile. I had to rethink everything from navigation to button placement.
