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.
