Questions teachers ask

Are these Cybersecurity games free?

Yes. Every game on this page is free to play, with no trial and nothing to buy. They are companions to our teaching units, and you can use them without owning one.

Do students need an account or a login?

No. A student opens the link and the game starts. There is nothing to install and no code to enter.

Do the games work on Chromebooks and phones?

Yes. They run in a web browser, so any device with one works, Chromebooks and phones included. Sound is off until a student turns it on, and the games project well for a whole-class round.

Is any student data collected?

The games never ask for a name, an email or an account, and nothing a student types or chooses in a game is sent anywhere. Where a game keeps a best score, it stays on that student's own device. The page itself counts anonymous visits with Google Analytics, the same as the rest of this site.

Do the games use real websites, emails or accounts?

No. Every email, web address, login screen, voice call and account in the games is invented and runs inside the page. Nothing connects to a real site or account, and nothing is sent anywhere.

What grade level are the games for?

Grades 9 to 12. Each game was built for one teaching day of a high school unit and uses the same vocabulary as that day's lesson.

Do I need the teaching unit to use a game?

No. Every game opens by explaining the idea it practices, so it can stand alone. It lands best right after the lesson it was built for, which is why each game is tied to a specific day of a unit.For classroom activities that need no screens, seeCybersecurity Activities for High School Students.
