I need a complete, production-ready mobile rummy app built for both iOS and Android. The game must run on a secure, real-time multiplayer engine, let players buy in with virtual Coins, and cash out seamlessly through an in-app wallet. Phone-number OTP will be the only sign-in method, so the flow has to feel fast and familiar for Indian players who expect SMS verification. A smooth, card-table interface, quick table matching, and an intuitive lobby are essential; the app should never leave users guessing where to tap next. On the server side, I’ll rely on you to design and deploy a scalable backend, integrate a payment gateway for deposits and withdrawals, protect every transaction with robust anti-fraud checks, and expose an admin panel where I can monitor game stats, resolve tickets, and adjust bonus campaigns. Deliverables • UI/UX design in Figma (or comparable tool) • Native or cross-platform codebase compiled for iOS & Android • Real-time multiplayer logic and matchmaking • Coin wallet with deposit/withdrawal workflow • SMS OTP authentication module • Admin dashboard + basic analytics • Store listings prepared and apps published under my accounts • One-month post-launch maintenance & bug-fix support I’m open to the tech stack you prefer—Unity, Flutter, React Native, or fully native—provided gameplay is fluid and App Store/Play Store guidelines are observed. Let me know your proposed architecture, timeline, and any similar gaming projects you have shipped so we can move forward quickly.
