How to play
Draw one path that fills every square.
That's the goal — no rules to teach. Here's how a round of Link Up runs.
2
Drag to connect the dots in order.
Trace from dot to dot in order without crossing your own line — a finger on the touchboard, or a mouse on any device.
Fill the whole grid in a single line.
The line has to pass through every square to finish. Take a wrong turn? Just drag back to undo — no penalty, no reset.
Where it earns its keep
Made for the in-between moments
Link Up is a solo puzzle — but it slots into the day three ways: a whole-class warm-up on the board, the answer to “I'm done, what now?”, or a quiet reset in the calm-down corner.
A whole-class warm-up
Project one puzzle and the room solves it together — the class calls the next turn while you (or the kid whose turn it is) drags. A two-minute soft start with zero prep and zero devices.
On the board · zero devicesThe early-finisher answer
Share one play link and “I’m done, what now?” answers itself. Self-paced, self-marking — you just see who solved it and how quickly, no chasing and nothing to grade.
One link · self-pacedThe calm-down corner
One absorbing puzzle, no timer and no score, is a reliable way to settle a wound-up brain. Hand it to a student who needs a reset and enjoy the hush that follows.
No timer · no scoreA fresh line every time
No two puzzles the same
Press New and a brand-new path appears — always solvable, never the same twice. There's nothing to write and nothing to mark: the puzzle is the content.

The library
Link Up is one shape of twenty-five
The Arcade is a library of classroom games — most fill from one topic box you type once. Link Up is the odd one out: the puzzle is the content, so there's nothing to prepare. When you do have a topic to teach, that same box turns it into a quiz, a crossword or a matching game.
- 25 game types, from logic puzzles to quiz shows
- Most fill from one topic box in under a minute
- Link Up needs none — press New for a fresh puzzle
Built for the classroom
AI fills it. You press play.
Every Arcade game starts from the same box: type what you're teaching and the content writes itself — questions, words, clues — ready for the board at the front of the room.
- Real content on your topic and grade — skim, edit or reroll before the class sees it
- Big type and chunky buttons, readable from the back row
- Students join with a code and a name — no accounts, ever

Do students need devices?
Any browser on any device via a play link — or project one puzzle and let the class direct the path square by square.
Is this like Zip?

Is it free?
Yes. Link Up is included on Boardee's free tier along with every game type.
Do students need accounts?
