I’m building a lightweight, addictively simple number-puzzle for iPhone and need a developer who can take it from concept to TestFlight. The core mechanic is a touch-based number puzzle—think quick arithmetic or pattern matching that ramps up in difficulty across multiple levels. Key gameplay pieces I absolutely need baked in: a visible countdown timer to keep the pressure on, seamless level progression (with difficulty parameters easy for me to tweak later), and a real-time leaderboard so players can compare scores worldwide. Touch controls should feel native—no swipes or virtual buttons, just straightforward taps. I’d like the leaderboard and player progress stored in a small, maintainable backend—Firebase, Supabase, or a lightweight custom REST service are all fine as long as it’s stable, secure, and cheap to run. Authentication can be anonymous to keep onboarding friction-free, but the system should still prevent obvious cheating. Deliverables • Xcode project in Swift or SwiftUI, ready for iOS 16+ • Live backend with API keys or environment file and concise setup notes • Basic admin view or script that lets me reset seasons or purge test scores • One round of bug-fixes after first TestFlight build If you’ve shipped casual games before and can keep the codebase clean and documented, let’s get this puzzle into players’ hands.
