Today's riddle
What has hands but can't clap?
How it works
Three steps, zero setup
No setup screen, no import wizard — Riddle of the Day lives on the same board as everything else and it's running before the class has sat down.

Let them wrestle with it
Take guesses all day if you like — the answer only shows when you tap.
Reveal the answer
The tap of triumph or despair. A new riddle arrives tomorrow.
Classroom ideas
Try it tomorrow
Three ways teachers actually run riddle of the day — steal one for tomorrow morning.
The official early-finisher station
'Try the riddle' permanently replaces 'what do I do now?' — and fast finishers stop being your scheduling problem.
Family homework, the nice kind
Send the day's riddle home unanswered. Tomorrow's reveal rewards whoever actually asked at dinner.
Write-your-own Fridays
After a month of dailies the class knows the shape — have them write their own, and the best one opens Monday.
I keep one board for the whole week — timetable, name wheel, timer — and just swap the background when the room needs a lift.
Same dock, one tap away 
Pairs well with
Every tool lives on the same board — these turn riddle of the day into a whole routine.
…and the rest of the dock is one tap away:
FAQ
Good to know
How hard are the riddles?
Pitched for classrooms — solvable with a think, not a search engine. The occasional one will humble the staffroom too.
Can I get a new one mid-day?
Yes — refresh if the class solves it embarrassingly fast.
Does the answer show right away?
Never — it stays hidden until you choose to reveal it. Suspense is the whole product.
Do I need an account to try it?
No — no login, no install. Your board saves on this device; an account only matters for using it across devices.
