3D Android Multiplayer Chess Game

I want a complete Android chess app that feels modern and social. The board and pieces should be fully 3-D, rendered smoothly on mid-range phones, with intuitive pinch-zoom and rotate gestures so matches feel immersive rather than flat.

Core gameplay centres on real-time online multiplayer. Players must be able to start a quick match against anyone worldwide or create a private room and invite friends. While a game is running, a lightweight in-app chat window should sit beneath the board so opponents can talk without switching screens.

Around the games, I need a simple community layer:
• Persistent friend list so users can add, remove, and directly challenge contacts.
• Elo-style ranking system with leaderboards that update automatically after each rated match.

Google, Facebook, or email sign-in are all fine as long as accounts sync the friends list and ranking data. For networking and real-time state sync I am happy with Firebase, Photon, or another stable solution; choose whichever you are most comfortable optimising.

Deliverables
• Android Studio project with clean, well-commented Kotlin or Java code
• 3-D assets for pieces and board (original or properly licensed)
• Backend configuration/scripts for multiplayer, chat, rankings, and friends
• Brief build & deployment guide so I can reproduce the release from scratch

Acceptance criteria
1. Two players on different devices can finish a full game with no desyncs.
2. Chat messages appear instantly (
