Unity Multiplayer Card Game (4 Players, Real-Time) – Photon + Firebase – MVP Development

@ASRADesigning

Hi Zentronix Team, I’m a Unity C# multiplayer developer with experience in real-time Photon multiplayer games. I can build your 4-player (2v2) card game MVP with clean scalable architecture, matchmaking, room/table system, turn timer, reconnect handling, and secure coin logic. I recommend Photon Fusion for better performance and stable state sync (PUN2 also possible if you prefer). All critical systems like coins, win/loss rewards, table entry, and ad rewards will be server-validated using Firebase/PlayFab to prevent cheating. I can deliver the MVP in 4–6 weeks with milestone-based builds, full source code on your GitHub, and proper documentation. Ready to start immediately.

Hi, I'm excited to bid on your real-time multiplayer card game project for Zentronix. With over a decade of experience in Unity development and a strong focus on multiplayer systems and anti-cheat measures, I’m confident we can deliver the high-quality MVP you need. Project Scope: - 4-player real-time gameplay (2v2 teams) - Auto matchmaking with table-based entry - Room-based system for persistent behavior - Turn-based gameplay with auto-play timeout - Disconnect & reconnect handling with state restoration Card Game Logic: - 13 cards per player - Turn order and trick-based gameplay - Team-based win/lose logic Table & Coin System: - Multiple tables based on entry fees (500, 1000, 2500, 5000, 10000 coins) - Coins locked at match start with distribution at end - Player remains at table if enough coins available Ad-Based Recovery System: - Rewarded ads integration for coin recovery (user-triggered only) - Server-side validation of ad rewards User Interface & Screens: - Home, table selection, in-game, profile, and leaderboard screens Backend & Security: - Firebase or PlayFab for user data, coins, and leaderboards - Server-authoritative validation for game state and coins to ensure no client-side trust Tech Stack: - Unity (C) - Photon PUN for robust real-time multiplayer support - Firebase or PlayFab for backend services - GitHub version control Deliverables: - Full source code on GitHub under your ownership - All necessary accounts (Firebase, Photon, Ads) controlled by you - Working APK builds per milestone - Detailed documentation and setup guide I will use Photon PUN due to its ease of integration and robustness for real-time multiplayer games. To ensure all 4 players see the same game state, we’ll implement server-authoritative updates to maintain consistency. Anti-cheat measures include strict validation on the server-side for coins and game states. If a player disconnects mid-game, their turn will be skipped or automatically resolved based on timeout settings to minimize disruption.

With more than a decade of software development experience encompassing mobile applications and web platforms, I am well-prepared to create the Unity Multiplayer Card Game you need for your company, "Zentronix". My current skillset centers around Flutter (Android & iOS), Node.js, and Laravel. While I haven't previously created multiplayer games, this project aligns with my broader expertise in real-time, high-performance solutions. Handling AI-powered applications, OpenAI integrations, custom SaaS systems among others has honed my skills at providing secure, scalable and reliable services that businesses need in increasingly multidimensional solutions. As a full-stack developer, I understand not only the implementation but also the seamless functioning of the whole system witnessed by my knowledge in backend management like database designs using Mysql, PosgreSQL or MongoDB to mention a few. Moreover, my capacity to build results-oriented applications is backed by having deployed several projects on cloud infrastructures such as AWS and GCP similar to what's required in your project with Firebase or PlayFab. Lastly, transparency is key in any project management. You'll receive regular updates as well as timely delivery of tasks thanks to my Git expertise, which will ensure the project remains under your ownership while facilitating version control.

Hi, I've built real-time multiplayer games in Unity and this project is well within my skills. Here are my answers to your questions: Photon Version: I'd use Photon Fusion (Shared Mode for MVP, upgradeable to Server Mode for tournaments). It offers better state sync and scalability than PUN2. Game state sync: All critical game logic runs server-authoritative via Fusion's NetworkObjects. Card dealing, turn order, and trick resolution are validated server-side. Anti-cheat: Coin transactions are handled entirely through Firebase Cloud Functions, the client never touches balances directly. Ad rewards are server-validated before credits are applied. Disconnects: Player state is snapshoted in Network on every turn. On reconnect, the room restores the full game state and the player rejoins seamlessly. I'm comfortable working on your own Firebase, Photon, and AdMob accounts, delivering via GitHub under your ownership, and releasing payment milestone by milestone. Best Regards!

✨✨✨ ✨✨✨ ✨✨✨ ✨✨✨✨✨✨ ✨✨✨ ✨✨✨ ✨✨✨✨✨ Hi, Dear. Portfolio : https://www.freelancer.com/u/seandinwiddie I’m confident I can help you build a solid, scalable Unity multiplayer MVP for Zentronix with a strong foundation in real-time networking, server-authoritative logic, and clean game architecture. With experience in Unity, Photon, and backend systems like Firebase/PlayFab, I focus on building production-ready multiplayer systems that are stable and extensible. I will start by designing the multiplayer architecture using Photon Fusion (for deterministic state sync and better tick-based control) and setting up server-authoritative game flow for coin and match validation. Next, I will implement matchmaking, room logic, turn-based gameplay, and reconnect handling with full state restoration. Finally, I will integrate Firebase/PlayFab backend systems, AdMob rewarded ads, anti-cheat validation, and UI screens with structured game flow and milestone-based delivery builds. The system will be built with strict separation between client and authoritative state, ensuring all critical logic (coins, wins, match outcomes) is validated server-side to prevent exploitation. The architecture will be modular so future expansions like tournaments and marketplaces can be added without refactoring core systems. Looking forward to collaborating. Best Regards. Sean D. ✅
