Abide all warnings such as needing to type something such as 'allow pasting' (such as in firefox). Now paste the blooket script in the console and hit enter. It is in fact true that many people create malicious scripts to steal data, however I have searched through the source code of every file and ran them risking my security, so you don't have to! I can verify that these files are 100% safe!

You may get a warning, which is completely normal. Okay, now at the top of the menu that just popped up go to the 'Console' Tab. Okay, now do Ctrl + Shift + I or Ctrl + Shift + C if Ctrl + Shift + I doesn't work for you. Simple! just hover over a button which matches the current gamemode you're playing, select the script you want, and click on it! After doing so, you will be redirected to a page with a bunch of weird complex text and things! (Example below) Simply just do Ctrl + A + C, doing so will result in you selecting the text, and copying it all.
