3D Android Online Chess Game

I want a polished 3-dimensional chess experience built specifically for Android that lets players challenge one another online in real time. Google Sign-In should be the only authentication method; once a user is signed in, they can jump straight into quick matchmaking or invite friends through their Google contacts. The core gameplay must feel exactly like standard chess, yet present the board in a smooth, rotatable 3D view with natural pinch-to-zoom. All legal-move logic, check, check-mate and draw detection need to run on the server so that no client can tamper with the rules. A lightweight server (Photon, PlayFab, your preferred equivalent) is fine as long as latency stays low and the implementation remains scalable. I would like clean, well-commented source code—Unity C# is ideal but I’m open if you can demonstrate an equally efficient Android workflow. Please separate game logic, networking, and UI layers so future updates are straightforward. Deliverables: • Signed APK ready for Play Store internal testing • Full project source with build instructions • Brief deployment guide for spinning up the multiplayer backend Show me a previous real-time multiplayer title you’ve shipped (even a small demo) so I can gauge your approach to latency and cheating prevention. Once we agree on milestones, I’ll move fast on feedback—let’s get players enjoying 3D chess on their phones.
