Blooket Game ID & Codes: How They Work

What is a Blooket Game ID?

A Blooket Game ID is a temporary numeric code that ties one classroom to one live game. When a teacher selects a question set and chooses a game mode in their dashboard, Blooket generates a fresh code and displays it in oversized text at the top of the projected screen. Every student joins the same session by typing that same code.

Game IDs are intentionally short and easy to read from the back of a classroom. They are not passwords and they are not tied to any student account — anyone with the code and a working browser can join until the teacher closes the lobby.

Where to find the code

If you are a student, the only place to get a valid Game ID is from your teacher. Codes are not listed anywhere on blooket.com because they only exist while a game is live.

• On the board: the teacher projects the lobby and the code appears at the very top of the screen.
• Posted in Google Classroom or Schoology: some teachers paste the code into the class stream so absent students can still join.
• Read aloud: if the code is hard to see, ask your teacher to repeat the digits.

How to enter it

1. Open a browser and go to play.blooket.com. This is the join page — it is different from blooket.com/login, which is for teacher accounts.
2. Type the Game ID into the box. The cursor jumps automatically; you do not need spaces or hyphens.
3. Press Join, then enter a nickname your teacher will recognize. Most teachers ask for a first name plus last initial.
4. Wait in the lobby until your teacher starts the round. Your nickname will appear in the on-screen list as soon as it's accepted.

How long codes stay active

Live game codes are valid only while the lobby is open. As soon as the teacher ends the game — usually within 5–25 minutes — that code stops working forever and a new game generates a brand new ID. If you arrive late and the code no longer connects, ask your teacher whether they have re-hosted the game.

Homework Mode is different. When a teacher assigns a set as homework, Blooket creates a join link with a much longer expiry (set by the teacher when they create the assignment, often a few days). Bookmark that link rather than trying to remember a code.

Common code problems

• "Game not found": Recheck every digit. The number 0 is often mistaken for the letter O, but Game IDs are always numeric.
• The code worked yesterday but not today: Codes do not roll over. Your teacher needs to host a new game and share a new ID.
• The lobby loads but freezes: Switch to a current version of Chrome, Safari, Firefox, or Edge. Old Chromebooks running outdated browsers are the most common culprit.
• The page won't load at all: Your school network may be filtering blooket.com — see our school restrictions guide for next steps.
