Hi Product Hunt 👋 Maker here, Mustafa. Number Guessr started as a side project to teach myself SwiftUI on nights and weekends. Six months later, it turned into a multiplayer game with real-time matches, daily challenges, and a story I'm pretty attached to. The game itself is a modern take on Bulls & Cows — a number-guessing game I played on paper with my dad as a kid. Each player picks a secret 4-digit number, then takes turns guessing. After each guess, you learn how many digits you got right AND in the correct position (bulls) vs. correct digits in the wrong position (cows). The first to crack the code wins. Three things I'm proudest of: 🎯 Onboarding under 30 seconds — from install to your first guess ⚡ Real-time multiplayer that feels instant — both players see each other's guesses with sub-200ms latency, built on Supabase Realtime 🌍 4 languages on day one — English, Turkish, German, Spanish Stack: SwiftUI (iOS 17+), Supabase (Postgres + Realtime), Firebase Analytics, RevenueCat, AdMob. Free to play with one optional subscription for unlimited lives and premium themes. No forced ads, no dark patterns. Would love your feedback — especially on the multiplayer experience. Cheers 🎯
