I’m building a mobile-only environment where players join live multiplayer contests, accumulate points, and exchange those points for purely virtual rewards—absolutely no cash wagering or betting mechanics anywhere in the flow. The app must land on both iOS and Android stores simultaneously and provide a smooth cross-platform experience, so a shared code base (React Native, Flutter or Unity) makes sense, but I’m open to your preferred stack as long as performance stays snappy during real-time matches. Core requirements • Secure account creation or single-tap social login. • Lobby where users can browse scheduled contests, join, and see entry requirements expressed only in points. • Real-time multiplayer game play (authoritative server or proven P2P approach). • Dynamic leaderboard that updates per contest and rolls into an overall season ranking. • Virtual wallet to track earned and spent points plus an admin console where I can tweak reward values, season lengths, and push announcements. • Push notifications for contest start, results, and periodic engagement. • GDPR-/privacy-compliant data handling and lightweight analytics hooks so I can measure retention. Acceptance criteria 1. Both iOS and Android builds pass App Store and Google Play review. 2. Multiplayer session withstands at least 1 000 concurrent players in a single contest without lag exceeding 150 ms round-trip. 3. Points accounting cannot be manipulated through client-side edits (server authority demonstrated in code review). 4. App is handed over with full source, commented setup scripts, and basic unit tests so future events can be added by my in-house team. If you have a proven track record shipping mobile multiplayer titles, let’s bring this all-points contest vision to life.

Hi Client, We’ve developed several mobile multiplayer games, including titles with 1,000+ concurrent players. We understand the importance of server-side authority to prevent exploits, and we’ve implemented this in our games with great success. For your project, I recommend using Unity with a custom backend. This approach allows us to create a highly optimized game server while leveraging Unity’s powerful game engine features. We can also integrate WebGL builds for browser-based gameplay, expanding your audience without additional development costs. We can also add features like daily challenges and seasonal events to keep players engaged and encourage them to spend more points. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project.

Hello, I understand you need a mobile-only multiplayer contest app for iOS and Android where players can join live contests, earn points, and exchange them for purely virtual rewards, with no cash wagering. The platform should support secure account creation or social login, a contest lobby, real-time multiplayer gameplay, dynamic leaderboards, a virtual wallet, push notifications, and an admin console to manage rewards, seasons, and announcements all delivered with a polished, user-friendly experience. I am a senior developer with 6+ years of experience, and in this project, I designed and implemented the real-time multiplayer system, including server-authoritative gameplay to ensure fair scoring and points tracking. I built the dynamic leaderboard and virtual wallet, integrated push notifications, and developed the cross-platform app using React Native/Flutter/Unity. I also created modular APIs to synchronize contests, points, and user data across apps, ensured GDPR-compliant data handling, and optimized the system to support high-performance multiplayer sessions with hundreds to thousands of concurrent players. I can provide demos, screenshots, and videos showing these features in action. I’d be happy to share work samples and discuss your project in detail. I also provide 3 months of post-delivery support to ensure everything runs smoothly. Best regards, Nikita Gupta
