There's a new logic puzzle here every day, and a whole class can solve it together in about ten minutes. It's free, your students don't need an account, and it works on a projector, on one shared device, or on paper.
Open today's logic puzzle Print today's logic puzzleOpen today's Logic Puzzle on the projector or the board. Read a clue out loud, let the class argue about it, and you tap the grid. Most days that's one lesson warm-up.
Small groups can share a Chromebook or tablet and race each other on the same puzzle. Everyone gets the same puzzle on the same day, so you can compare answers at the end.
Print today's logic puzzle with a grid big enough to pencil into and the solution on the page after it. It builds in your browser, so give it a minute before you hit Print.
The puzzles get harder through the week, so pick your day:
Monday is a good first try. Friday is a real challenge, even for adults.
Students don't need an account. Everything here plays without signing in, and there's nothing to install. If a student does sign in, they shouldn't use their real name as their display name (the account page asks them not to). The site does count visits and taps to see what's working, and the privacy page says exactly what it keeps.

I'd love to hear how it goes in your classroom, good or bad. Write to Jeff@bossfeed.fun and a person reads it.
