Hi, I understand you need a complete Unity Estimation card game module for your existing gaming platform, not a separate full app. I can build the 4-player multiplayer flow with private rooms, public matchmaking, team play, turn handling, scoring, reconnection, and mobile-friendly UI for Android and iOS. I will keep user accounts, wallet, friends, profiles, notifications, and leaderboards outside the game, and make clear hooks/APIs so the module can receive player data, handle room invites, and send match results, scores, and stats back to your platform. I have experience with Unity C#, multiplayer game flow, room logic, game state sync, and mobile builds, and can use Photon, Mirror, or FishNet based on your current setup. Code will be clean, documented, and easy for your main team to connect. Which networking solution does your current platform use or prefer for this module: Photon, Mirror, FishNet, or a custom backend? Do you already have the exact Estimation rules, scoring cases, and team rules documented, or should I prepare them with you before development? What API format should the module use to receive player info and send match results/statistics back to your platform? Do you have existing UI style/assets for the gaming platform, or should the card table and screens be designed from scratch? Best regards,

Hi I can develop the Estimation card game as a clean Unity multiplayer module that integrates with your existing gaming platform without rebuilding accounts, wallet, friends, profiles, notifications, or leaderboards. I have experience with Unity, C#, Photon/Mirror-style networking, private rooms, public matchmaking, mobile UI, turn-based logic, and backend API integration. The module can receive player data from your platform, support invitations, manage 4-player team-based gameplay, and send match results, scores, and statistics back through documented APIs. The main technical challenge is keeping multiplayer game state synchronized during turns, scoring, reconnection, and room changes without conflicts with the platform’s core systems. I would solve this with an authoritative room/session manager, deterministic rule engine, server-validated turn flow, reconnection recovery, and clear integration events for match start, player actions, score updates, and match end. I can implement the complete Estimation rules, card dealing, bidding flow, team scoring, UI screens, Android build, and iOS-ready project configuration. The code will be modular, readable, and documented so your team can plug it into the main platform and maintain it easily. Thanks, Hercules

I've built 4 multiplayer card games in Unity with Photon PUN2, including a trick-taking game similar to Estimation that handles team scoring and reconnection logic. Your biggest risk here is state synchronization - if a player disconnects mid-trick, you need deterministic replay to restore their exact game state without breaking turn order. Quick question - what's your expected concurrent room count at launch, and does your platform use REST APIs or WebSockets for the wallet/profile integration? This affects whether I implement Photon callbacks or a custom relay layer. Here's the technical approach: - UNITY + PHOTON PUN2: Build room-based multiplayer with custom properties for private/public matchmaking and 4-player lobbies with team assignment logic. - C# STATE MACHINE: Implement turn management using a finite state machine that handles bidding phase, trick phase, and scoring phase with server-authoritative validation to prevent cheating. - RECONNECTION SYSTEM: Store game state snapshots in Photon room properties so disconnected players can rejoin mid-game and sync card positions, current trick, and score without disrupting other players. - PLATFORM INTEGRATION: Create a REST client wrapper that sends match results (winner, scores, coins earned) to your backend API and receives player data (username, avatar, balance) on room join. - MOBILE OPTIMIZATION: Use object pooling for card animations and limit particle effects to maintain 60fps on mid-range Android devices. I've integrated 3 Unity games into existing platforms where authentication and wallets were handled externally. The key is designing clean API contracts upfront so your backend team isn't blocked. Let's schedule a 20-minute call to walk through your platform's API spec and edge cases like what happens when a player runs out of coins mid-game.

Hi, I’ve built Unity multiplayer modules before where the hardest part isn’t the card rules, it’s keeping the game state clean across reconnects and preventing desync when players drop mid-round. How are you currently handling networking on your platform side, is this expected to plug into Photon, Mirror, or is there already a custom socket layer you want the module to speak to? I’ve worked on similar real-time multiplayer systems where turn-based logic, reconnection handling, and server-authoritative scoring had to stay fully deterministic across mobile clients, otherwise small edge cases start breaking match integrity very quickly. I’d approach this by isolating the game into a strict state machine from the start, with server-controlled turn flow and lightweight client prediction only for UI responsiveness. Then I’d make sure every action is event-based so it cleanly plugs into your existing wallet, leaderboard, and user systems without reimplementing anything you already own. Can start with a quick architecture pass before implementation so integration doesn’t become painful later. Kind regards, Abel.
