As soon as all students have joined, lock the lobby using the padlock icon on the Kahoot screen.
The truth is, in late 2025 and early 2026, Kahoot! rolled out its most aggressive server-side anti-bot update yet. The result? Nearly every major Chrome extension—from Kahoot Ninja to Flooder and Bot Killer—was broken overnight. But is the fix permanent? And are there still ways to use legitimate tools for testing and simulation?
Follow installation instructions, usually requiring Developer Mode in Chrome.
In addition to backend fixes, Kahoot provides hosts with several built-in tools to maintain control over their game lobbies and prevent any future exploitation. Player Identifier kahoot bot extension fixed
Thus, when you see "Kahoot bot extension fixed" on Reddit or GitHub, it usually means that specific extension stopped working—not that all bots are permanently defeated.
A specialized extension that connects to OpenAI's API to scan questions in real-time and suggest or auto-select the best answer.
Many third-party browser extensions claiming to bypass Kahoot's security contain hidden malware, adware, or data scrapers. As soon as all students have joined, lock

So, if you do manage to get a flooder working, know that the host might have an extension that removes you immediately.
Many "fixed" extensions found on third-party sites (outside the official Chrome Web Store) are actually disguised malware designed to steal browser data.

By inputting the unique Game PIN—a public identifier displayed on the teacher’s screen—a user could instruct the extension to generate scripts that simulate hundreds of distinct users joining the lobby. The result was immediate chaos: the teacher’s screen would fill with names, the game would lag, and the educational flow would be shattered. For the student initiating the attack, it was a display of technical rebellion; for the teacher, it was a frustrating hurdle to learning.
