How to improve anti-botting:

Sometimes, just an antibot is not enough... Here are ways to prevent bots from joining your games to the best of your ability

  1. Enable Friendly Names - This limits what names can be used, making the antibot more powerful
  2. Enable 2FA - Some bots try to brute force this. The Antibot detects this and can block them.
  3. Enable Team Mode - While team mode no longer prevents most bots from joining, it can help filter out some bots that use the same patters for teams. Some bots may still not support team mode, so this will help.

Features planned:

  • More Blocking Options (When new botting patterns are found).
  • Prevent answers during team talk

Support for other play.kahoot.it scripts

If you are creating your own play.kahoot.it scripts, it will not work with Kahoot Antibot normally. You need to do the following:

  1. Run at document-start
  2. Create or get window.antibotAdditionalScripts to []
  3. Add your code as a function to the array

// @run-at       document-start
// ==/UserScript==

window.antibotAdditionalScripts = window.antibotAdditionalScripts || [];
  // code to run

To detect if the antibot is active, you can check for the kantibotEnabled variable (v3.0.0+)
