Hey everyone :wave: !! Wanted to share a little story. I've been heads-down building another micro-SaaS, and honestly I just needed a break from it — something fun and quick to clear my head. It's FIFA World Cup season, so I told myself "I'll just make a fun little World Cup predictor." Famous last words. One day of vibe coding later, it had somehow grown into a full thing: all 48 teams, 104 matches, a complete knockout bracket builder, community match voting, a daily trivia quiz, a penalty shootout minigame, streaks, and a global leaderboard. So much for "quick and simple" :sweat_smile: The core idea I'm actually proud of: instead of making one bracket, you build multiple "universes" — one where your team wins, one realistic one, one chaos one — and track them all. Felt like a more honest way to predict a tournament nobody can actually predict.
