Let Anyone Play a Lesson With a Code
Turn on a play code so anyone can open a lesson at berdee.app/go, with no class or roster to set up.
Sometimes setting up a class is more work than the lesson itself: a substitute day, a holiday activity, a tutoring trial, a family night. Turn on a lesson's play code, and anyone who types it at berdee.app/go plays the lesson right away. Nobody needs to be on your roster, and nobody signs in.
Players are anonymous. Berdee doesn't ask their name, they don't appear on your Students page, and they don't count toward your plan's student limit. Their answers aren't added to any student's grades.
Turn on a play code
- Open the lesson from your Lessons list.
- In the Play code card, choose Turn on play code.
- Share the code, or choose Copy link to share a link that opens the lesson in one step.
Write the code on the board, put it in a newsletter, or post the link on your class website. For a walkthrough with screenshots, see the tutorial Let anyone play a lesson with a code. Unlike a student's own access code, a play code is meant to be shared.
The lesson has to be ready for students first: if it has problems to fix, Berdee says so and leaves the code off. Only lessons you made or copied can have a play code. Purchased lessons can't, because their license covers your own students.
How players use it
A player types the code at /go, in capitals or not (turkey2026 works for TURKEY2026), and the lesson starts. If they reload the page or open the code again in the same browser, they carry on where they were. Their sign-in ends when they close the browser.
The card shows how many players have opened the lesson.
Choose your own code
On a paid plan you can choose a code that's easy to say aloud, like TURKEY2026. Choose Change code, type your code, and choose Save code.
- Use 4 to 20 letters and numbers.
- Every code is unique across Berdee, so a code someone else already uses is taken.
- A code with exactly eight letters and numbers that looks like a student's own access code (such as
ABCD2345) can't be used. Add or remove a letter.
On every plan, Get a new random code replaces the code with a new one.
Turn it off or change it
Choose Turn off to stop new players. Players already in the lesson can finish it. When you turn it back on, the same code works again.
Changing the code makes the old one stop working right away.
Common questions
Which version of the lesson do players get? The newest version you've saved that's ready for students. If you're in the middle of an edit that leaves the lesson with problems to fix, new players get the last version that was ready. A player already in the lesson keeps the version they started.
Can I see players' answers? Not yet. Berdee records each play, so results will be there when that view arrives.
What if lots of people use the code at once? A whole class at once is fine. To prevent abuse, about 60 new plays a minute from one network is the limit; past it, players see "Too many tries. Wait one minute."
