Multiplayer Conversion for Puzzle Portal

Job ID: 40250864

Budget: $30 – $250 USD

I have 25 browser-based puzzle games written in plain HTML, CSS and JavaScript (preview them here: https://hsi811727-cmyk.github.io/Puzzelgames/). I’m ready to move them to puzzelgamesonline.com and turn each title into a multiplayer experience aimed squarely at generating revenue through advertising.

What I need:
• Every game refactored so two or more players can compete in real time or turn-based mode without altering the core mechanics.
• A lightweight but scalable backend (matchmaking lobby, room management, basic chat, leaderboards) deployed on a suitable server or cloud instance you help me configure.
• Ad monetisation built in from day one—banner, interstitial and video placements integrated cleanly so play isn’t interrupted.
• Final code pushed to the existing GitHub repo and the live site set up under SSL on puzzelgamesonline.com.

Please bring experience with multiplayer frameworks (WebSockets, Socket.io, Colyseus or similar) and front-end optimisation for both desktop and mobile. Once complete, I want to be able to add new games or adjust ad logic without touching the core infrastructure, so clear documentation is part of the hand-off.

If this sounds like your kind of project, tell me how you’d tackle one sample game first and your preferred tech stack for the server side.
