I’m building a full-featured chess game for iOS and Android that lets users play in two ways: solo against a strong, adjustable AI and head-to-head through real-time online multiplayer. The core mechanics of classical chess are already defined, so what I need is the complete app: clean, intuitive UI, a reliable chess engine integrated for single-player, and a secure backend that handles matchmaking, friend invites, and ranking for multiplayer. Cross-platform technologies such as Unity, Flutter, or React Native are all acceptable as long as the final experience feels native on both stores. Key deliverables • Fully compiled iOS (.ipa) and Android (.aab) builds ready for TestFlight / Play Console • Source code with clear documentation • Online services set up (lobby, ELO rating, chat optional) • Adjustable AI difficulty (at least three levels) • Basic tutorial screens and settings menu I’ll provide App Store assets and any branding; you handle coding, chess logic, and deployment support until the first public release. If this sounds like a project you can own end-to-end, let’s talk timelines and milestones.

< Hi - Bojan here from Serbia > "REAL-TIME MULTIPLAYER CHESS FOR IOS & ANDROID" — combine reliable chess rules, adjustable AI, and live ranked games in one app I’d use Flutter for the mobile client and keep chess rules on a shared game layer so AI and online matches follow exactly the same move validation. Multiplayer would use server-authoritative game state with reconnect handling, matchmaking, and ELO updates so players cannot desync or manipulate results. I’d build the board and offline AI first, then multiplayer, ranking, invites, and store-ready builds with regression tests for legal moves, clocks, reconnects, and game results. Do you already have a preferred chess engine, or should I select and integrate one?

Hi, have you considered how you plan to handle the latency requirements for the real-time multiplayer moves to ensure the game remains snappy even on varying mobile network conditions? To build your chess app, I will utilize Flutter for a high-performance, single-codebase cross-platform build, integrating the Stockfish engine via a C++ bridge for adjustable AI difficulty. The backend will be powered by Firebase for real-time matchmaking and secure ELO calculations, ensuring seamless synchronization between players. For a smooth multiplayer experience, I recommend implementing a WebSockets-based architecture with a "move-validation" layer on the server to prevent cheating. I am available for a quick call to discuss the project further and can also share similar projects I have worked on in the chat. Thanks, Ruchi.

My approach would be to build the cross-platform client in Flutter or React Native, with a proven chess engine such as Stockfish for the solo mode. For multiplayer, I’d implement server-authoritative game state, matchmaking, friend invites, ELO/ranking, reconnect handling, and secure move validation so players can’t manipulate results from the client. I’d structure the work in milestones: Chess board, rules, UI, settings and tutorial Stockfish integration with 3+ difficulty levels Real-time multiplayer, lobby, invites and ELO Testing, edge cases, performance and polish iOS/Android builds, TestFlight/Play Console deployment support I’ll also keep the architecture clean and documented so you can continue extending features after launch. A couple of important questions: do you already have a preferred backend/hosting setup, and should multiplayer support private friend matches as well as public matchmaking?

Hello, We can develop your complete cross-platform chess game for iOS and Android using React Native, with a proven chess engine for adjustable AI and a secure backend for real-time multiplayer. The app will include solo play with at least three difficulty levels, matchmaking, friend invitations, ELO rankings, optional chat, tutorials, settings, and a polished native-style interface. We will also handle testing, deployment support, and submission-ready .ipa and .aab builds. You will receive clean source code, backend setup, technical documentation, and support through the first public release. Before starting, could you please confirm: Do you have UI references, or should we create the complete design? Should users play as guests, registered users, or both? Do you require timers, tournaments, leaderboards, and game history? Should multiplayer chat be included in the first release? What are your preferred budget and launch timeline? After confirming the MVP scope, we can provide accurate milestones and a fixed quotation. Best regards, VD Infotech

Hey — saw your post about building a mobile chess game with AI and multiplayer. One big challenge with chess apps is balancing AI difficulty while keeping multiplayer latency low. Are you planning to build the AI engine from scratch or integrate an existing one like Stockfish? I’ve worked on game logic integration and real-time multiplayer syncing before, so I get the pitfalls around performance and fairness. If you share your current game design or spec, I can take a look and give you some feedback on next steps.
