Boardee Arcade · Word games
Crossword
Fill in words across and down.
End-of-unit revision that feels like the Sunday paper. Clues force recall, not recognition — students have to produce the word, letter by letter, which is exactly the point.

How to play
Fill the whole grid using the clues.
That's the goal — no rules to teach. Here's how a round of Crossword runs.
2
Type the answer into the grid.
Type straight into the lit squares. Any letter shared with a crossing answer is already sitting there, so the grid gets easier as it fills.
Fill every square correctly to finish.
Nothing to submit — the grid completes itself the moment the last square is right.
Ways to play
One grid, three ways to solve it
The same Crossword works as a front-of-class solve, a live device round, or take-home revision. Pick at press-play — nothing to rebuild.
On the big screen
Project one grid and the whole class solves it together — students call the answers while you (or the kid whose turn it is) types. No devices, no setup, no codes.
Zero devices · zero prepLive on their devices
Students go to boardee.app/join and type the six-digit code — phones, tablets, chromebooks, any browser. Everyone gets the same grid, and the round is scored on the squares filled in and time.
Join code or QR · no student accountsIn their own time
Share one play link and the same grid becomes revision, homework or early-finisher work. Results roll in as each student finishes — clues solved and time, no chasing.

Anything with an answer is a clue
If your students can answer it, it's a clue — and the Arcade links them into a grid. Type the topic; AI writes the clues and interlocks the puzzle.

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.
