A classroom quiz game that runs on your Mac and keeps going when the internet doesn't. Students join with a code. No accounts, no ads.
The app is free · No subscription · macOS 14+
Enter your school email and we'll tell you if EDU pricing applies automatically. We don't store or send anything — the check runs right here in your browser.
Your teacher's screen shows a 6-letter code. Type it here and you're in — no account, no app, no download.
Or type the full address — like quizblast.net/r/YOURCODE — into your browser's address bar.
Under two minutes, start to finish: set up a game, students join, the board goes up — and both ways a class can get in.
Three screens, one game. Nothing installs anywhere, and nothing about your students leaves the room.
Students open a link or scan the QR and type a first name. No app, no account.
Your Mac runs the whole game: the board, the buzzer order, the scores. It stays on your desk.
The class sees the clue and the scores. Your answers and controls never go up on the wall.
Team play costs extra on other platforms, and a real Jeopardy board usually means juggling a second website. Here it's one app, and for educators all of it is free.
The game lives on your Mac and your classroom's own network.
Unlock the roster for a moment, mid-game — no restart, no lost scores.
Reconnects are automatic; nobody re-enters anything.
Project the game display; keep the control panel on your Mac.
No logins, no rollout, no accounts to manage — the app just runs.
Choose a mode and a deck — or build your own in minutes.
Project the QR code. Students scan it and they're in the lobby.
Start the game — the board goes up and the class is playing.
Every game mode, every deck, whole-class games — free, forever. Not a trial, and not just for teachers. The only thing that costs money is the optional cloud service.

The short version: the app is free, for everyone. Cloud Pro is a separate subscription for joining over the internet — on your own network, the app works completely without it.
Cloud Pro renews automatically at the interval you pick — monthly or yearly — until you cancel, which you can do anytime, and every charge is covered by a 30-day, no-questions refund policy.

14+I work in IT for a K‑12 school district. When a classroom tool breaks, my phone is the one that rings — so I know exactly how these tools fail: the Wi‑Fi chokes, the filter blocks the site, the free plan ends mid-semester.
I built QuizBlast to be the tool that doesn't do that. It runs on your Mac, so the internet can't take it down. It has no student accounts, so there's no student data to worry about. And for teachers the app is free — really free — because you already spend too much of your own money on your classroom.

Load-tested on a Mac with every student connected at the same time and a game actually running — not just joining.
Run on one Mac over its own loopback, so these numbers measure the app. In a real room your access point gives out long before QuizBlast does — which is what cloud mode is for.
