I’m building a skill–based “real money” shell game and need a Unity developer who can get an MVP into the App Store and Google Play. The core mechanic is the classic three-shell shuffle: players watch the shuffle, pick a shell, and instantly see whether they were right. Everything must feel physically authentic and visually polished in a realistic 3D style—think lifelike table, lighting, shells, and fluid shuffle animations. Scope • Platforms: one codebase that ships to both iOS and Android from day one. • Game modes: single-player (practice or solo cash), real-time multiplayer head-to-head, plus scheduled tournament brackets. A simple lobby and basic matchmaking UI are enough for now. • Real-money hooks: for this MVP, stubs or sandbox calls that simulate deposits, wagers, wins, and payouts are fine; I mainly need the architecture ready for a payment SDK drop-in later. • Anti-cheat & fairness: server-authoritative shuffle seed, basic tamper detection, and analytics logs so I can audit outcomes. • Tech: Unity (URP is acceptable), C#, Photon or equivalent for quick multiplayer spin-up, and simple backend endpoints (Node/Express or Firebase functions) for results storage. Deliverables 1. Unity project with commented, clean C# code. 2. iOS TestFlight and Android Internal Test builds. 3. Read-me covering build steps, third-party services, and where to plug in payment APIs. 4. Short video or GIF demo showing each game mode working on a device. Acceptance • Both platforms install and run without crash on current OS versions. • Shell shuffle randomness matches server seed when replayed. • Each mode correctly declares winners/losers and updates a placeholder balance. • Visuals match the realistic style brief (no placeholder gray boxes). If you’ve shipped multiplayer Unity titles before and can move fast on an MVP, let’s talk timelines and any questions you have about the flow. The concept is a "Streak Challenge" where players pay an entry fee (e.g., $5) to play a visual tracking game. If they track the winning object through 5 increasingly difficult levels of shuffling, they win a large jackpot. Crucial Requirement: This is NOT a gambling game (RNG). It is a Game of Skill. The winning object must physically travel across the screen and be trackable by the human eye. The code must reflect true physics-based movement, not random teleportation. Core Features to Build: 1. The Game Loop: • 3D Coin Shuffle mechanic (Shell Game style). • "Streak" Logic: 5 Levels of difficulty. Level 1 is slow (3 coins); Level 5 is "Blur Speed" (5 coins). • "Cash Out" System: After every win, the user sees a "Cash Out" or "Double or Nothing" prompt. 2. The Assets: • Winning Coin: Gold Crown. • Losing Coin: "X" or Skull. • Must allow for custom branding (Logo) on the back of the coins. 3. The "Fairness" Feature (Priority): • Slow-Motion Replay: If a user loses, they must be able to watch a "Replay" of the shuffle at 0.5x speed to prove the game did not cheat. 4. Backend/Security: • Basic user wallet system (Deposit/Withdraw capabilities). • Secure server-side logic (Node.js or Python) to prevent client-side hacking/cheating. Technical Requirements: • Frontend: Unity (C#) is preferred for the best physics and frame rate (60fps is mandatory for tracking), or React Native if you can guarantee performance. • Backend: Node.js, Python, or Firebase. • Payment: Experience integrating Stripe, PayPal, or specialized gaming gateways is a huge plus. Budget: [Insert your budget range here, e.g., $2,000 - $5,000 for the MVP] To Apply: Please include the word "CROWN" at the top of your proposal so I know you read the details. 1. Have you built a real-money or skill-based gaming app before? 2. How would you ensure the shuffle animation is smooth and trackable on older phones? 3. Share links to 1-2 relevant apps you have built.

Hi, this is Elias. I’ve reviewed your project and understand you’re building a skill-based, real-money shell game with realistic 3D physics, multiplayer, and streak-based progression. With extensive experience shipping Unity games with multiplayer and physics-driven mechanics, I’m confident I can deliver an MVP that’s polished, performance-optimized, and ready for iOS and Android. I’d love to discuss how we can bring your vision to life. A few questions to clarify the approach: Q1: For the "streak" levels, do you want difficulty scaling purely via shuffle speed, or should coin count and pattern complexity also evolve? Q2: Will the "Cash Out" and "Double or Nothing" prompts need server-side validation for placeholder balances, or is client-side simulation acceptable for MVP? Q3: Are there preferred frameworks for the backend wallet system, or is Node.js/Firebase flexible? Q4: Should the slow-motion replay be exportable/shareable, or just visible within the app for auditing purposes? Deliverables: fully-commented Unity project, iOS TestFlight and Android Internal Test builds, backend endpoints for game logic and wallet, read-me for payment API integration, and short video demo of all modes. Looking forward to connecting and refining timeline and MVP scope. Regards, Elias

Hi CROWN — the key challenge in skill-based shell games is proving fairness while maintaining smooth, trackable physics at high frame rates across devices. I build Unity C# games with true physics-driven motion, ensuring the winning object physically travels and can be visually tracked without RNG shortcuts. I would implement server-authoritative shuffle seeding with Photon or equivalent networking so outcomes are verifiable and tamper-resistant. The MVP would include realistic 3D assets, URP lighting, fluid animations, and a slow-motion replay system that deterministically replays the exact shuffle at reduced speed. Multiplayer head-to-head and tournament modes would share the same authoritative logic, with clean wallet stubs for deposits, wagers, and payouts ready for later payment SDKs. Backend endpoints in Node.js or Firebase Functions would securely record results, balances, and analytics for auditability. The result is a polished, App-Store-ready MVP that clearly demonstrates a game of skill with transparent fairness. Thanks, Hercules

Hi CROWN I have read your project details for the skill-based shell game MVP. I understand you need Unity app for iOS and Android with real 3D coin shuffle, streak levels, cash out, replay proof, and secure wallet stubs. Not gambling, pure skill tracking. My approach will be Unity with URP for smooth 60fps physics on all phones. I will build 3D coins with gold crown winner, skull loser, and custom logo support. Shuffle uses real physics movement, server seed from Node.js backend controls path so its fully trackable. 5 levels from slow 3 coins to blur speed 5 coins. After win, cash out or double prompt shows. Loss triggers 0.5x slow motion replay to prove fairness. Multiplayer uses Photon for head-to-head and tournaments. Wallet stubs ready for Stripe later with anti-cheat logs. I will deliver TestFlight and Google Play internal builds with full readme. Code clean and commented for easy payment SDK add. Thanks & Regards Abhishek Questions: Unity or React Native preferred? Node.js or Firebase for backend? Any coin design images ready?

CROWN Hi, I can deliver an MVP in Unity (C#) that ships from one codebase to iOS (TestFlight) and Android (Internal Test), with realistic 3D visuals, smooth animations, and a clean architecture ready for real-money SDKs later. -True physics-based shuffle: coins move continuously using Unity physics/animation curves — no teleporting, no RNG tricks. -Server-authoritative seed: shuffle paths derived from a server seed so outcomes can be replayed and audited. -60 FPS focus: URP optimization, fixed timestep tuning, and device profiling to keep tracking smooth even on older phones. - Fairness proof: built-in 0.5x slow-motion replay when a user loses. -Modes: single-player, head-to-head multiplayer (Photon or equivalent), and basic tournament brackets. -Wallet stubs: deposit/withdraw, wagers, streak logic, cash-out vs double-down — architected for Stripe/PayPal later. Answers to your questions 1. Yes — I’ve worked on real-money and skill-based game architectures (wallets, fairness, anti-cheat). 2. By locking physics + animation to deterministic paths, capping motion blur, and profiling for 60fps on low-end devices. 3. I can share relevant app demos privately (some are under NDA). You’ll get clean, commented code, test builds on both platforms, and a project that’s genuinely verifiable — not smoke and mirrors. Happy to discuss timeline and budget fit.
