I’m building a mobile version of the classic tile-based game (Okey / Rummikub style) and need an experienced Unity developer who can take it from prototype to App Store and Google Play release. Core gameplay The match must run in real-time, not turn-by-turn, so players see each move as it happens. All core rules, tile shuffling, jokers, melding, and scoring need to mirror the traditional tabletop experience. Cross-platform multiplayer A single, shared server is essential—players on iOS and Android should sit at the same virtual table. I’m open to Photon, Unity Netcode, or another proven networking stack as long as latency stays low and reconnections are handled gracefully. Social layer A built-in friends list with the ability to send and accept invites is required on day one. I don’t need public matchmaking or in-game chat yet, but the architecture should leave room to add those later without rewriting core systems. Art & UI I can supply basic tile and table graphics if you prefer to focus on code, but if you have UI/UX strengths it’s a plus. The end result should feel polished on phones and tablets in both portrait and landscape. Deliverables • Complete Unity project with clean, well-commented C# scripts • Working iOS (.ipa) and Android (.aab) builds ready for TestFlight / internal testing • Short setup guide covering server configuration, third-party SDK keys, and build steps If you’ve shipped a real-time multiplayer mobile title before—especially a card or board game—please share a link or APK. I’m ready to start as soon as I find the right fit.

Hi, I am a software engineer with over 16 years of experience building production applications and real-time connected systems. I can structure this Unity game around a deterministic rules engine, server-authoritative table state, low-latency move synchronization, reconnection recovery, and a friends/invite layer that can later expand to matchmaking and chat. I would begin by locking the Okey/Rummikub rule set and scoring variants, then build a playable cross-platform table, integrate the selected networking backend, optimize the UI for phones/tablets and both orientations, and prepare TestFlight/Android testing builds with setup documentation. Relevant private multiplayer work cannot be shared publicly, but I can show it privately during our discussion. The listed budget is realistic for a networked prototype or first milestone rather than the complete polished, store-ready product described. Is this project intended to start with that milestone, followed by staged development? I’d be glad to discuss the rules, assets, backend choice, and release plan with you.

Hi there, I’d love to help turn your Okey/Rummikub concept into a polished real-time multiplayer game. Unity is a strong fit here, and I can handle the core gameplay, cross-platform networking, reconnection logic, friends/invites, responsive UI, and release-ready iOS/Android builds. The important part for a game like this is getting the multiplayer architecture right from the beginning. I’d make the server authoritative for tile state, moves and scoring so both platforms stay synchronized and players can reconnect without corrupting a match. I’ll also keep the code clean and modular so matchmaking, chat or other social features can be added later without rebuilding the game. I can start by reviewing your current assets/prototype (if available), confirming the exact Okey/Rummikub rules you want, and then building the first playable multiplayer table for you to test.

Hello, I hope you're doing well. I've shipped several real-time multiplayer Unity titles, including a turn-based card game where I built the networking layer on Photon with custom reconnection logic so players could rejoin mid-match without losing state. That project taught me a lot about keeping latency low across mixed iOS and Android clients sharing one server. For your Okey game, I'd start by locking down the server authority model, then map the tile rules to deterministic game states that both platforms can trust. I'd also sketch the friend-list schema early so invites work on day one and public matchmaking can slot in later without a rewrite. Could we schedule a short call this week? I'd like to confirm which networking stack you're leaning toward, and walk through how you want reconnections handled when a player drops mid-round. Thank you, Jasjot

The numbers above are rough placeholders for now. Real budget and timeline come after a quick look at scope together. Building a real-time Okey game is a fun but genuinely tricky problem. It's not just the tile logic, the melding validation, joker rules, and scoring all need to stay in sync across devices in real time, and the reconnection story matters a lot for a mobile game where players drop signal constantly. Getting that right from the start means the social layer and any future matchmaking can slot in without touching the core networking code. Here's how we'd approach this: - Networking core: Photon Fusion or Unity Netcode for GameObjects as the multiplayer backbone. Fusion in particular handles reconnects and late-join cleanly, which is exactly what a mobile tile game needs. We'd run authoritative game state server-side so clients can't desync. - Game logic: C# state machine covering the full Okey ruleset, tile shuffle, joker substitution, meld validation, and scoring. Clean separation between game logic and presentation so rules are easy to tweak. - Cross-platform builds: single Unity project targeting iOS and Android from day one. We'd wire up the Xcode export and Gradle config early so there are no nasty surprises at build time. Builds ready for TestFlight and internal track on Play Console. - Social layer: friends list and invite system built on top of Photon's lobby or a lightweight custom REST layer, depending on what fits the hosting budget. Designed so public matchmaking and chat can drop in later without touching the core tables. - Setup guide: a short but complete doc covering server config, Photon app ID setup, signing keys, and build steps, so handing the project off is painless. Once we've had a short call to go through the full scope and asset situation, we'll put together a proper proposal with milestones, deliverables breakdown, and a firm price. What does your timeline look like, and do you have a preference between Photon and Unity Netcode? Best, 96 Studio

Hello, I think the key challenge here isn’t just getting Okey/Rummikub rules into Unity - it’s making real-time multiplayer feel reliable when iOS and Android players are sharing the same table, including reconnects and latency handling. I understand you need the prototype taken all the way to TestFlight and Google Play internal testing, with synchronized gameplay, traditional shuffling/jokers/melding/scoring, and a friends/invite system that won’t require a rewrite when matchmaking or chat is added later. For a relevant approach, I’d structure the game around an authoritative multiplayer state so tile moves, turns/actions, scoring, and reconnections remain consistent across clients. I’d also keep the social layer decoupled from the core game logic and build the mobile UI to support both portrait and landscape. I can provide a clean Unity project with organized C# systems, server/SDK configuration documentation, and production-ready iOS/Android builds. One question before starting: do you already have the prototype/gameplay code, or should I build the multiplayer architecture and core game systems from the current concept?

Hi, I can take your Okey/Rummikub style Unity prototype toward a cross-platform multiplayer release, with the architecture built around real time gameplay from the start. I’d use Unity with C# and a proven networking solution such as Photon or Unity Netcode, depending on your existing prototype and server requirements. The game logic should remain server-authoritative so tile shuffling, jokers, melds, moves and scoring stay consistent for every player at the table. I’ll focus on: * Real-time iOS ↔ Android multiplayer * Reliable synchronization with low-latency updates * Reconnection and dropped-connection handling * Traditional rules, shuffling, jokers, melding and scoring * Friends list with send/accept invites * Clean separation between game logic, networking and social systems * Responsive portrait/landscape UI for phones and tablets * TestFlight ready iOS and AAB Android builds * Setup/build documentation and SDK configuration I’ll also structure the code so future matchmaking, chat or other social features can be added without rebuilding the core game architecture. I don’t want to send you a fabricated APK or claim a shipped multiplayer title I haven’t actually delivered. Instead, I can show you my Unity/C# work and explain how I’d approach the multiplayer architecture. I’m available to start immediately and can first review your current prototype and recommend the networking architecture before development begins.
