I want to build a Tournament App for Battle Royale games like Free Fire, BGMI, CODM, where users can buy slots through online payment, play the match, and based on their kills or Booyah (placement), they receive winnings in their in-app wallet. Main focus: Payment system + Auto slot booking + Result & Kill based winnings + Wallet credit + UPI withdrawal (no KYC) + Full admin control. --- User Side (Mobile App) OTP Login (Mobile number) List of upcoming tournaments with entry fees, slot count, prize pool, match time Slot Booking through UPI / Card / NetBanking (Razorpay / Cashfree / Paytm gateway) On successful payment, slot is automatically confirmed View match details, room ID/password (after booking) Submit match result (kills, Booyah) with screenshot as proof View tournament result, winnings, wallet balance Wallet → Add Money / View history / Withdraw to UPI without KYC Push Notifications (slot booked, match reminder, payout done etc.) --- Admin Panel (Web Dashboard) Create & manage tournaments (mode, entry fee, kill rate, booyah bonus, slots, time) Manage room ID/password (only booked users can see) View all booked slots, users & payments Result Management → check proofs, edit kills, DQ teams, finalize results Automatic winnings calculation based on kills & booyah rules Credit winnings to user wallets Withdrawal Requests → approve & release payouts through UPI payouts (no PAN needed) Dashboard with statistics (total tournaments, revenue, payouts, disputes) User management (ban/unban, check wallet, transaction history) Notification broadcast (match announcements, maintenance, offers, etc.) --- Payment & Wallet System Integrated secure payment gateway (UPI, card, netbanking) Slot is booked only after payment success Winnings credited automatically to app wallet after results are finalized Withdrawals through UPI payouts (admin approval or auto) No KYC or PAN verification required for withdrawal All transactions (entry fee, winnings, withdrawals) recorded in wallet history --- Additional Features Firebase push notifications Basic Anti-cheat / Result verification through proof images Referral system (optional, can add later) Responsive, clean & fast UI Secure backend with proper database structure --- Tech Preference (Flexible) Frontend: Flutter / React Native Backend: Node.js (NestJS) or Python (Django/FastAPI) DB: PostgreSQL / MySQL Admin Panel: React / Next.js Payment Gateway: Razorpay / Cashfree / Paytm (India focused) --- Goal I want a fully functional app with admin panel, where I have complete control over tournaments, payments, and user management. After the match, I will enter or verify the results manually — and based on that, winnings will be credited to players’ wallets, and they can withdraw anytime via UPI without any KYC. App name must be : Arc Esports
