The Blooket flooder of 2021 was never a sophisticated exploit. It was a blunt instrument of playful rebellion, wielded by sleep-deprived students in pixelated Zoom squares. It crashed quizzes, frustrated teachers, and forced a beloved platform to grow up. Today, attempting to flood a Blooket game is nearly impossible—but the memory of that wild, ungoverned spring lives on. In the annals of edtech lore, 2021 will always be the year the bots joined the class. blooket flooder 2021
Bots could be programmed to "spam" the answers or, in some cases, manipulate the scoring system.
To prevent anonymous bot floods, Blooket introduced hosting settings that required players to be logged into verified Google or Blooket accounts to join specific sessions. This eliminated the ability of external scripts to generate anonymous, randomized bot names. Encrypted Game Handshakes : Some advanced scripts could answer questions at

A "flooder" in online parlance refers to a script or tool designed to overwhelm a service with artificial traffic. The was a specific genre of JavaScript-based bot that automated the creation of fake player accounts and forced them to join a specific Blooket game lobby. These were not sophisticated hacks—they were simple, often open-source scripts shared on GitHub, Glitch.com, and Replit, requiring only a Game ID to launch.

Every automated bot injected into a lobby requires server bandwidth and processing power. During the peak of the 2021 trend, massive influxes of bot traffic caused frequent server crashes, slow loading times, and connection errors for legitimate users globally. Disrupted Instructional Time
Blooket flooders exploited this WebSocket connection. Here is the step-by-step process of how a typical 2021 flooder worked:
The underlying websocket communication protocol was upgraded. Blooket encrypted the handshake tokens required to authenticate a user into a game lobby, meaning third-party scripts could no longer easily mimic a authentic user connection. The Legacy of the 2021 Exploit Era
Users would enter the Blooket game code, specify the number of bots they wanted, and the script would generate dozens, sometimes hundreds, of anonymous players (bots) to fill the lobby.
