Android Colour Prediction Game

I need a colour-prediction game built specifically for Android phones. The app should feel lightweight and intuitive for end-users while giving me complete control through a secure web-based admin panel. Core play: users predict the next colour, stake virtual coins, and instantly see the outcome. An in-game currency wallet must handle balance updates, bet deductions, and winnings in real time. All coin movements should be recorded for audit and displayed clearly to each player. Admin panel: from any browser I want to create or close rounds, adjust win ratios, credit or debit coins, view player histories, and export basic reports. Role management for additional operators would be a plus but is not mandatory at launch. Technical notes • Target device: Android (phones and tablets). • Platform: mobile app built with any stable stack you are comfortable with—Flutter, React Native, native Java/Kotlin, etc.—as long as the final APK performs smoothly. • Security: protect API endpoints, validate every transaction server-side, and obfuscate the client build. • Deliverables: full source code, APK ready for Play-Store submission, and hosted admin panel with setup guide. I will test by installing the APK, topping up demo coins, playing several rounds, and checking that the admin panel reflects every transaction accurately and without lag.
