Whether you are a student looking to kill time between classes, a worker on a lunch break, or a competitive gamer who wants to practice building mechanics without launching Fortnite, these GitHub-hosted duels are your best bet.
Repository: Lonsdale201/sveltethegamer Play at: lonsdale201.github.io/sveltethegamer This is perhaps the most sophisticated open-source 1v1 platform available. Built with Svelte and TypeScript, it uses WebRTC Peer-to-Peer (P2P) connectivity, meaning no central server is required. It offers multiple strategic mini-games including "Color Duel" (Tic-Tac-Toe style), "Tower War" (a back-and-forth battle), and "Shadow Code" (a Mastermind-style code-breaking challenge).

: The browser version interfaces with active global matchmaking servers via secure WebSockets, keeping latencies low enough for real-time competitive duels. Step-by-Step: How to Deploy a 1v1 Mirror via GitHub Pages
GitHub Pages offers a clever workaround. It's a legitimate, free static web hosting service used by millions of developers to host project documentation, portfolios, and personal websites (all subdomains of github.io ). As a widely used, non-gaming site, GitHub Pages often escapes standard content filters. Savvy members of the gaming community realized they could upload the entire source code for 1v1.LOL to a GitHub repository and host it via GitHub Pages. The result is [username].github.io/[repository-name] —a completely playable version of the game on a domain that network filters are less likely to block.

| Control | Action | | :--- | :--- | | W / A / S / D | Move your character | | Mouse (LMB/RMB) | Aim, Shoot, and Build structures | | Z / X / C / V | Switch between different build pieces (e.g., walls, ramps) | | 1 / 2 / 3 | Change weapons (e.g., rifle, shotgun) | | Shift | Sprint |
In building games, you have a limited number of materials (wood, stone, metal). Do not waste 200 materials building a skyscraper. Build smart: One wall, one ramp. Conserve materials for the final duel.
