Teen Patti & Roulette Game Build

I’m gearing up to add two casino-style titles—Teen Patti with real-time multiplayer and a Fruit Roulette experience—to my Flutter mobile app. Both games must run smoothly on Android and iOS and follow a minimalistic, clean custom theme that blends easily with the app’s existing UI.

Development stack & integration
• Unity is my preferred engine, but if you have a stronger alternative that still ships an SDK/API for Flutter, I’m open.
• The current backend is Node.js; REST endpoints and WebSocket (or Socket.IO) hooks already exist, so the games need to authenticate, exchange chips/coins, and report results through those channels.
• Clear, well-commented code and developer-friendly documentation are essential so my in-house team can maintain the project long-term.

Deliverables
1. Complete Unity project files for Teen Patti (multiplayer) and Fruit Roulette (single or multiplayer at your discretion).
2. A lightweight SDK or DLL with example Dart calls that plugs straight into my Flutter codebase.
3. End-to-end connectivity to the Node.js backend, including win/loss callbacks, chip balance updates, and table creation for Teen Patti.
4. Basic admin controls (e.g., force-end a table, adjust RTP, view active sessions).
5. Step-by-step build instructions and a short video or PDF walkthrough.

What I’d like to see from you
• Links or builds of similar casino/card projects you’ve shipped (Unity preferred).
• A realistic timeline for both games, broken into major milestones.
• Your estimated cost and any questions you need answered before locking scope.

If you thrive on Unity multiplayer logic, REST/WebSocket integration, and sleek minimal UI design, I’m ready to get started right away.
