Realtime Color Prediction Platform

I plan to launch a colour-prediction gaming platform that runs fast 30-second and 1-minute rounds similar to BDG Game. Players will log in, fund their wallet, join a round, pick a colour, and see instant results—so the site must be extremely responsive and rock-solid on both desktop and mobile. Key workflow • User registration and secure login • In-site wallet with real-time balance updates • Funding and cash-out via Bank Transfer, UPI, Paytm and on-screen QR code scans • Automatic settlement at the end of each 30-sec / 60-sec game User panel features • Profile management (basic details, KYC placeholder) • Live wallet view plus full deposit / withdrawal history • Game history with round ID, bet, outcome, profit / loss • Built-in referral system that tracks invites and credits bonuses automatically Admin panel essentials • Dashboard with live player count, current pool, revenue, and KPIs • Controls to open/close games, set odds, pause the service, or adjust timers • Manual balance adjustments, transaction logs, and fraud flagging • Referral and bonus configuration, banner and notification management Technical notes Speed matters: every 30-second round should clear and post results instantly without manual refresh, so efficient websocket or equivalent real-time tech (Node.js, Socket.io, Laravel Echo, etc.) will be needed. All financial moves must be double-recorded—one entry for the user ledger, one for the system ledger—and reconciled whenever the admin requests. A clean, modern UI in React, Vue, or an equally snappy front-end framework is preferred, but I’m open as long as it stays lightweight and mobile-friendly. Acceptance criteria 1. Place a test bet, watch countdown, get an automatic win/loss credit in the wallet in under one second after round closes. 2. Complete a deposit via UPI sandbox; balance appears instantly and entry in admin ledger matches. 3. Trigger a withdrawal to demo bank details; admin approves; wallet updates and ledger shows the debit. 4. Referral link creates a new user, both accounts reflect the bonus defined in settings. 5. Admin can change the timer to 60 s and the game engine adjusts without a restart. Deliver all source code, database schema, and deployment instructions so I can host it on my own VPS once testing passes.
