FAQ
Good to know
How many students can play?
Solo up to four players per puzzle — pairs sharing a device works especially well. Or project one grid and solve it together as a class.
Do students need devices?
Not necessarily. Solve one crossword together on the projector, or have students join from their own devices with a code or a shared play link.
Can AI write the clues for my topic?
Yes. Hand it your vocab list — or just a topic and grade — and it builds a linked grid with clues in under a minute. You can edit anything it writes.
Is it free?
Yes. Boardee's free tier includes every game type, crosswords included.
Do students need accounts?
Never. Students join with a code and a name — no emails, no passwords. Teachers don't need an account to try it either.
