I already have the complete game source files ready to go; what I need now is a smooth deployment on my own server under my registered domain. Once the files are live, every visitor must sign up and log in before they can play, so please build a straightforward, secure registration and authentication system (email + password, password reset, session control). All games will remain completely free to play, yet I want the codebase prepared for monetisation. Wire in a clean payment-module scaffold that can switch between PayPal, Stripe, or Square simply by dropping in the API keys later—my applications are still pending, so the checkout screen should stay hidden or disabled until I flip the switch. Beyond that, connect the domain, configure SSL, tune the server for performance, and present the games in a responsive layout that works on both desktop and mobile. I’ll need a brief hand-off guide showing how to update games, swap keys, and redeploy. Acceptance will be based on: • Site reachable via my domain with valid SSL • Mandatory sign-up/login functioning and secure • All provided games launching without errors • Payment gateway code ready, but safely dormant • Clear deployment & maintenance notes supplied
