Trail

How to play

• Drag (or tap cell by cell) to draw one continuous line starting at 1.
• Hit the numbers in order — and fill every cell of the grid before landing on the last number.
• Tap any cell on your line to rewind to it. ↺ starts over.
• Every board has exactly one solution, machine-verified before publication.

If you enjoy Zip-style daily path puzzles, this is the same one-line habit with unlimited free play and an archive. Sister puzzles: Gridlings.

FAQ

How do you play Trail?

Draw one continuous line that visits every cell exactly once and passes through the numbered waypoints in ascending order. Drag through cells, or tap the next cell to extend the line; tap back to retract.

Is there a new Trail puzzle every day?

Yes — a new daily board goes live at 00:00 UTC, the same board for every player worldwide, with streak tracking. Unlimited free play in three difficulties and a full archive of past dailies are also free, with no account and no ads.

Can Trail be solved without guessing?

Yes. Every published board is machine-verified before release: a solver proves exactly one solution exists and is reachable by logical deduction, so there is always a provable next step.
