Real-Time Color Prediction Game

I need a full-stack solution for a fast-paced color & number prediction game built around 30-second and 60-second live rounds. Players choose Red, Green, or Violet (plus digits 0-9), and the platform instantly resolves each round, so low-latency architecture is essential. Core requirements • Game engine that can spin up concurrent 30-s and 1-min gambling rounds, publish odds, lock betting at the cut-off, and announce winners in real time. • An admin back office where I can manually set or override every round’s result, edit user balances, and approve or reject deposits and withdrawals. Granular logs of each change must be retained. • Integrated wallet supporting UPI and QR-code flows for deposits and cash-outs, with automatic reference matching and status updates. • Mobile-first UI/UX: responsive layout, touch-friendly controls, and smooth transitions so it feels like a native app when installed as a PWA. • Engaging front-end with live animations, dynamic timers, and immediate feedback to keep users highly interactive and immersed. Tech flexibility is yours—Node/Express, Laravel, or any real-time-friendly stack is fine, provided you can hit sub-second update speeds and guarantee data integrity. Please outline: 1. The framework and real-time service you plan to use (Socket.IO, WebSockets, Firebase, etc.). 2. Your approach to PWA packaging and offline handling. 3. Security measures for wallet operations and admin actions. 4. Milestone schedule from prototype to production deployment. Acceptance criteria • Round lifecycle completes in under two seconds from bet lock to result broadcast. • Admin overrides reflect instantly on all connected clients. • Successful test transactions via UPI and QR workflow. • Lighthouse mobile performance score ≥ 90. If this fits your skill set, share relevant live demos or GIFs showcasing similar interactive gambling projects, plus a concise timeline to launch.
