Hi I understand you need a Unity mobile landscape prototype for Da Conquer, starting with the Da SayKa stage and its custom Rummy-style gameplay rules. I have experience with Unity, C#, mobile UI, turn-based card game logic, draw/discard pile systems, hand management, rule validation, win detection, and basic-to-intermediate AI opponent behavior. The main technical challenge is making the custom SayKa rules reliable while also giving the AI enough decision logic to draw, discard, build sets, and play in a believable way. My solution would be to build the core game engine around clean rule-checking, card state management, turn flow control, SayKa button validation, and AI decision scoring. I can create a clean landscape UI for the player hand, AI area, draw pile, discard pile, turn indicator, action buttons, and win/round feedback. I would work from your GDD and translate the rules into modular Unity scripts so future stages or rule variations can be added more easily. I can also provide samples of relevant Unity, mobile, card game, or AI opponent work for review. Overall, I can help turn Da SayKa into a playable, testable Unity prototype with solid gameplay foundations. Thanks, Hercules

Hi, Card games vs AI is direct portfolio territory — I've shipped poker/card games and Ludo (turn-based mobile, similar draw/play/pass rhythm). Unity + C# + mobile is weekly work, and I was also lead dev on Mine Quest 2 with 500K+ downloads on my own Google Play account (XDEV STUDIO). For the Rummy AI, my approach: track the discard pile to estimate what opponents need, evaluate hand by partial sets / runs and their completion probability, weight draw/discard decisions on which cards advance my sets vs hand opponents theirs. That's the "intermediate" sweet spot — feels smart without being unbeatable. I'd structure prototype delivery as milestones: 1) rules engine + draw/discard + win detection (validates the GDD), 2) UI layout and turn flow, 3) intermediate AI + SayKa button logic, 4) polish + iOS/Android builds. Three clarifications before I quote firmly: 1. Budget range? Not visible in the brief. 2. Could I see the GDD? Custom Rummy rules can be simple or labyrinthine — affects estimate significantly. 3. "Intermediate AI" — basic legal-play with simple heuristics, or discard-pile-tracking with probability evaluation? Noticed your side note about a Bazaar-style card game in development — happy to discuss that direction on a call if useful; deckbuilder/auto-battler mechanics are a fun space. 10+ years game dev. Preferred Freelancer, 5.0/34 reviews, 33 completed, 95% on-budget. Best, Hieu

Hi, I understand you need a Unity mobile landscape prototype for Da Conquer’s Da SayKa stage, including custom Rummy-style rules, draw/discard piles, set-building, SayKa button logic, win detection, and player-vs-AI gameplay from your GDD. I have strong experience with Unity mobile development, turn-based/card game systems, clean mobile UI layouts, rule-driven gameplay logic, and intermediate AI decision-making for valid moves, set formation, and discard strategy. I would build the prototype in milestones covering core card engine, Da SayKa rule implementation, AI opponent logic, responsive landscape UI, gameplay testing, and Android/iOS-ready project handoff. Q1: Can you share the GDD so I can confirm all Da SayKa rule details? Q2: Should the prototype include art/animations, or focus mainly on functional gameplay first? Q3: Do you need APK/TestFlight-ready builds or just the Unity project source? Best regards.

Most prototypes fail not from missing features but from brittle, tightly-coupled logic that makes rule changes and AI tuning slow — for Da SayKa you need a data-driven card/hand model and a predictable AI so rules from the GDD can be iterated quickly. I’ll implement a modular Unity prototype (landscape) with a clear game state manager, data-driven card definitions (ScriptableObjects/JSON), draw/discard pile systems, turn flow, SayKa button & win detection. The intermediate AI will be rule-based with heuristics for set detection, risk scoring for draws/discards, and adjustable parameters so behavior can be tuned without code changes. Recommended stack: Unity (C#), Unity UI (Canvas) for mobile layout, ScriptableObjects/JSON for content, simple local state machine for turns, and optional lightweight JSON-config for AI weights. No server required for the prototype — all on-device. I’ll deliver in milestones (core rules + UI → AI opponent → polish & tuning) so you can test iterations. This approach keeps code modular for future features. Similar work: built Program Pro’s adaptive decision engine (served mobile clients) and ReThinkology’s mobile UX — both demonstrate mobile UI/UX and designing tunable decision logic for clients. Quick question: does the GDD include the full card set and all scoring/edge-case rules, or should I design a data-driven card/schema to capture incomplete rule details? If you like, I’ll draft a 3‑milestone plan next.

Hi, I'm Osama from Virginia. I understand you're looking to build a mobile landscape Unity prototype for Da Conquer, and the key priority here is a playable first stage with solid turn flow, rule handling, and a believable AI opponent. I can help you build this in a structured and maintainable way without unnecessary complexity. I have experience working with modern stacks such as Unity, mobile app development, and game design. My focus is always on building practical, production-ready systems that are easy to extend and maintain. For this project, I would first review your GDD and current setup, then design the core card logic, implement the draw/discard and set-building flow, and test the win detection, SayKa button, and AI decisions step by step. I can review your current setup first and improve it without unnecessary rebuilding. I’m comfortable working in milestones and keeping communication clear throughout. If you already have the GDD and any existing Unity scene or scripts, I can start from there and shape the prototype around the exact rules you want. I'm available to start immediately and can adapt quickly to your workflow. Regards, Osama

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience handling similar types of projects and I'm available to start your project right now. I bring deep expertise in Unity 3D, Game Development, Mobile App Development, Game Design, AI Development, and Prototyping with over 10 years of experience. One of the key challenges in projects like Da Conquer is implementing custom card game rules while ensuring smooth turn management, accurate set validation, reliable win detection, and AI decision-making. My approach would be to build the game logic as modular systems, making the Da SayKa rules, draw/discard mechanics, AI behavior, and future game expansions easy to maintain and extend. I have a couple of quick questions. • Does the GDD already define all Da SayKa rule variations and edge cases for set validation? • Do you have card assets/UI designs available, or should placeholder assets be used for the prototype phase? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos

Hi there! I understand you need a Unity mobile prototype for “Da Conquer / Da SayKa” with custom Rummy-style rules, AI opponent logic, and a clean landscape UI for iOS and Android. The main challenge here is building reliable game logic (rules + win detection) while also creating a smart enough AI that can make reasonable card decisions. I have strong experience in Unity development for mobile games, especially turn-based systems and card-style mechanics. I’ve worked on projects involving deck management, rule-based gameplay logic, AI decision systems, and responsive mobile UI/UX in Unity. I also focus on clean architecture so game rules, AI, and UI are separated for easy updates and scaling. My approach will be to first implement the core game loop: draw/discard piles, player vs AI turns, and rule-based set building. Then I will build the SayKa logic and win detection system to ensure accurate gameplay flow. After that, I will implement an intermediate AI that evaluates hand strength, forms sets, and makes logical draw/discard choices. Finally, I will design a clean mobile-friendly landscape UI with clear interaction flow and smooth turn indicators, fully aligned with your GDD. check our work https://www.freelancer.com/u/ayesha86664 Do you already have the full rule breakdown for Da SayKa, or should I help formalize it into technical game logic first? Let me know if you’re interested & we can discuss it. Best Regards Ayesha
