I need a web-based solution that lets players top-up their favourite mobile games on both iOS and Android in just a few clicks. The flow should be simple: the user selects the game, enters their player ID, picks a denomination, then checks out using Credit/Debit Card or popular Indian UPI wallets such as Paytm and PhonePe. Speed and reliability are essential, so please build the recharge logic to trigger instantly once payment is confirmed and show real-time order status to the customer. I will also need an admin panel where I can add new games or offers, view transactions, and manually verify or refund orders when needed. Clean UI/UX, secure payment-gateway integration, and well-structured, documented code are the core deliverables. If you have previous experience with gaming top-ups or payment APIs in India, that will be a big plus.
