Android Color Prediction Game

I need a complete color-prediction game for Android, packaged with its own admin panel. Players will install the app, sign up or log in with their phone numbers, and immediately be able to place their color picks in short, repeating rounds.

From the admin side I want one, clear priority: I must see the outcome of every upcoming round before it is shown inside the game. A simple dashboard that lists future results in real time is enough for now; the ability to expand later to user management or outcome control can stay in mind, but it is not part of this first milestone.

Core flow for users
• Phone-number OTP authentication
• Home screen showing current timer, available colors and wallet balance
• Result screen that reveals the winning color after each round and stores it in history

Core flow for me
• Web-based or in-app admin panel (your recommendation)
• Secure login
• Live table of rounds that includes: round ID, start time, and the pre-revealed winning color
• Search / filter so I can quickly pull past results

Deliverables
1. Production-ready APK + all source code (Kotlin or Flutter is fine; suggest what you’re fastest with).
2. Admin panel source and compiled build.
3. Setup guide to deploy the backend/API on a standard VPS (Node.js, Laravel, or Firebase—again, open to your expertise).
4. One short hand-off call or screen-share so I can verify that the upcoming-result feed matches what players later see.

Make sure everything is clean, lightweight, and easy for me to maintain or extend. If you have a previous color-prediction or real-time game project, mention it; I’ll review demos quickly and move forward.
