Daily One Line

Start at 1 and draw a single line without lifting your finger, passing through every cell exactly once. Numbered cells must be visited in order (1, 2, 3 …) and the line must end on the highest number. You can't visit a cell twice, and you can't cross a wall between cells. There's a new puzzle every day, and everyone solves the same one. Stuck? Trace back along your line to erase it, or tap any cell on the line to continue from there.

How to play

1. Put your finger on the cell marked 1.
2. Drag to neighboring cells to draw one line. Every cell must be visited once.
3. Visit numbered cells in order and finish on the highest number. Walls can't be crossed.
4. Go back to erase, or tap a cell on your line to continue from there.
5. Today's puzzle only counts once. The clock starts when you open it and keeps running even if you leave.

Tips for a better record

• Corner cells have few ways in and out, so plan how to pass the corners first.
• Don't rush straight to the next number. Take a route that fills the empty cells on the way.
• If a cell looks like it's about to get cut off, go through it now. Cells next to walls get trapped easily.
