Satta Matka Android App Build

I need a full-featured Android application that lets users play a classic Satta Matka game wrapped in a traditional Matka look and feel. The flow should cover user registration, wallet management, number selection, live draw updates, and automatic payout calculation. Please weave an intuitive payment-gateway integration (UPI, cards, net-banking) into the wallet so deposits and withdrawals happen seamlessly.

Alongside the player app, I also require a secure web-based admin panel. From there I should be able to:

• open and close markets, post results, and adjust odds in real time
• view, filter, and settle bets
• monitor user balances, deposits, withdrawals, and overall revenue

A clean REST or GraphQL API between app and admin is preferred so scaling is painless.

Key points to keep in mind
• Platform: Android only (Kotlin or Flutter is fine—whichever gets smoother performance)
• Primary function: Satta Matka gameplay with real-time results
• Design: traditional Matka theme—vibrant reds, earthy backgrounds, and familiar number-drawer visuals
• Security: OTP login, encrypted data at rest, and checksum-verified payment callbacks
• Deliverables: Android APK + complete source code, admin panel code, SQL/NoSQL schema, brief deployment guide

I’m happy to answer technical questions quickly so you can move fast; just outline your proposed tech stack, past Matka or gaming work, and an estimated timeline in your bid.
