I’m looking to acquire a fully finished HTML5 browser game that already has in-app purchase functionality wired in. My focus is desktop-browser play, so please only respond if your title runs smoothly on Chrome, Firefox, Edge, and Safari without mobile-first workarounds. I’m not commissioning fresh development—only ready-to-ship products interest me. If you have a complete build, please share a live URL or WebGL/HTML5 demo, brief tech stack notes (Canvas, WebGL, Phaser, Construct, etc.), and a rundown of how your purchase system is implemented. I’m open to any genre provided gameplay is polished and the revenue loop is proven or clearly demonstrated. Deliverables I expect once we agree: • Full game source and asset bundle • Documentation explaining build, deployment, and purchase flow • All necessary licences or a written transfer of commercial rights If you have analytics or previous revenue data, that will help speed up my decision. Looking forward to seeing what you’ve already built.

Hi, I understand you are looking to acquire an already completed HTML5 browser game rather than commission new development, with desktop-browser compatibility and an existing in-app purchase system. I can help identify and evaluate suitable ready-to-ship titles based on your requirements, including Chrome, Firefox, Edge and Safari compatibility, the underlying technology such as Phaser, Construct, Canvas or WebGL, gameplay quality and the existing purchase implementation. For each suitable title, I can review the available live/demo build, technical documentation and commercial transfer terms, and verify what is actually included in the acquisition: source code, game assets, build/deployment files, dependencies and transferable licences or commercial rights. I’ll also distinguish between a genuinely operational purchase flow and a placeholder/demo implementation, and review any available analytics or historical revenue information where the seller can legitimately provide it.

Hello, I am Truong. I understand you are not looking for new game development—you want a finished HTML5/WebGL game that can be transferred, deployed, and monetized immediately. I can help evaluate a ready-made build carefully before you commit, focusing on browser compatibility, purchase flow, source/assets, licensing, and deployment readiness. I think you want to avoid buying a game that looks complete but still needs major technical work. I can review the live demo/build, inspect the implementation and purchase architecture, verify the desktop experience across Chrome, Firefox, Edge, and Safari, and check that the delivered source and documentation are sufficient for future maintenance. I can also review analytics or revenue evidence where available and identify any gaps before purchase. If you already have a candidate game, send me the live URL/demo and available technical details. I’m ready to review it and give you a practical assessment before moving forward.

You need an existing, polished desktop HTML5 title with a working purchase loop — not a build started from scratch — so the key questions are demo quality, browser parity, and clean rights transfer. I build real-time browser systems (Canvas/WebSocket games with state machines and recoverable execution flows) and have shipped multi-provider payment pipelines with subscription and transaction tracking, which is exactly where most ready-made games fall short. My approach: 1) send you a private live URL plus a short recording showing Chrome, Firefox, Edge and Safari playthroughs; 2) walk you through the stack and the purchase flow end-to-end, including server-side validation; 3) hand over full source, assets, build/deploy documentation and a signed commercial rights transfer. Which genre and monetisation model fits your audience best?

I can help review the technical stack, validate the game architecture, and provide the required documentation and transfer details. A few quick questions: • Do you have a preferred game engine or technology stack (Phaser, Construct, Unity WebGL, custom Canvas/WebGL)? • Are you mainly interested in a specific genre, or are you open to evaluating different polished HTML5 games? I would be glad to discuss your acquisition criteria and review available solutions that match your requirements. Best regards, Carlos

Hi, the most important part of your requirement is finding a genuinely production-ready browser game with a complete source package, clear ownership transfer, and a working monetization flow rather than an unfinished prototype that still requires significant development. My background is in game development and interactive applications, and I have experience building and deploying games across multiple platforms. Before discussing transfer, I would like to confirm the exact requirements around commercial rights, source ownership, and the in-app purchase/payment workflow to ensure the package aligns with your publishing goals. One question: are you specifically looking for a game with live payment gateway integration already active, or would a complete game with a demonstrated virtual-currency purchase system also be acceptable? I can provide further details, deployment information, and ownership terms through Freelancer chat if the existing game matches your requirements. Regards, Muhammad Asad Ali
