Blooket Cheats
05k0nz's legacy is safe
Blooket-Cheats is a repository containing scripts and a small web interface for Blooket game modifications. It organizes cheat scripts by game mode and provides methods for loading them through bookmarklets, a GitHub Pages interface, or browser console execution. The repository includes folders for cheats, tutorials, auto-update logic, page styling, and front-end code. From a software perspective, it is a browser-script collection focused on manipulating a web game environment. However, using cheats can violate platform rules, undermine fair play, and create problems in classroom or competitive settings. It is best described neutrally as a JavaScript-based browser scripting repository rather than as a recommended gameplay tool. -

webmc
PoC Minecraft client written in Javascript
WebMC is an experimental proof-of-concept Minecraft client written in JavaScript that runs directly inside a web browser. Instead of requiring a traditional desktop installation of the game, WebMC allows users to connect to Minecraft servers from a browser environment. The client communicates with a WebSocket proxy that bridges the browser connection with the standard Minecraft server protocol. By leveraging browser technologies and modern JavaScript libraries, the project demonstrates how a voxel-based game client can run using web-based graphics and networking systems. WebMC also showcases how browser-based applications can interact with multiplayer game servers using real-time communication channels. The project is primarily intended as a technical experiment and educational demonstration of browser-based game development. -

A userscript for Blooklet, compatible with tampermonkey
This script is created for research and education purposes. Abusive usage of this script is not tolerated and the author is not responsible for any damage or harm caused due to usage of the script.

This request only happens once, so once the request is made, the feature can no longer be enabled/disabled. The ability to unlock skins requires the name of the skin to be known, include those of which that are hidden. If you know a skin name and would like to contribute, please open an issue and it will be added. Install Tampermonkey, add the contents of index.js to tampermonkey. Restart your browser and use right ctrl to activate/deactivate the menu. -

Tower Building Game
HTML5 Canvas Tower Building Game
Tower Building Game is a small game project — likely implementing a classic “tower defense” or “tower-based” game — designed to showcase game-development fundamentals such as rendering, game logic, user interaction, and possibly simple physics or animations. As an open-source repository, tower_game aims not only to deliver a playable game, but also to serve as a learning resource or template: developers can inspect its code, understand how game loops, input handling, asset management, and state updates are organized. This makes it useful for programmers who are curious about games but don’t want to start from scratch. Because simple games often involve fewer dependencies and easier build processes than full-scale games, tower_game can be a good starting point for hobbyist developers, students learning programming or graphics, or for integration as a mini-game inside larger projects. Additionally, its open-source nature lets contributors fork and improve it.
