I’m building a puzzle game that runs seamlessly on web browsers, iOS, and Android while letting players earn real money. The earning model is three-fold: every rewarded ad they watch, every level they clear, and each special achievement they unlock adds to a personal USD balance. Players have individual, secure accounts and may cash out once they reach $5; a flat $1 platform fee is automatically withheld and the remainder is sent by bank transfer. I need the complete package—gameplay mechanics, polished UI/UX for touch and desktop, and a single code base (Unity, Godot, or similar) that compiles to WebGL, IPA, and APK/AAB. A robust backend must handle authentication, wallet ledger, anti-fraud checks, and an admin dashboard where I can approve payouts, manage ad-network keys (AdMob, Unity Ads, etc.), view analytics, and ban cheaters. Integration with Firebase (or equivalent) for real-time analytics and crash reporting is essential. Deliverables • Production-ready puzzle game with a minimum of 50 handcrafted or procedurally generated levels • Responsive interface that preserves the same experience across devices • Backend APIs, database schema, admin panel, and payout module wired to a bank-transfer API • Proper reward callbacks so players are credited instantly after ads, level completions, and achievements • Commented source code, build instructions, and deployment to a staging web URL, TestFlight, and Google Play Console Acceptance criteria 1. Store-compliant builds for all three targets 2. Accurate wallet updates for each rewarded action 3. Withdrawal request of $5 shows $4 net to the player and fires a successful payout webhook 4. Smooth performance with 2 000+ concurrent users on mid-tier devices Proposed timelines and milestone breakdowns are welcome—I respond quickly to keep development moving.
