    Blooklet-utility-mod

    Blooklet-utility-mod

    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. Features such as skin unlocks work by intercepting blooket's request to its server and modifying the response data to unlock skins. 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.
