Master the Number Trail
Learn how to plan routes, use checkpoints and avoid dead ends.
Plan your route
Look at the numbered checkpoints before moving. Consider how your path can reach them without trapping unused squares.
Use the edges
Pay attention to corners and narrow spaces. They offer fewer possible directions, so plan those moves carefully.
Finish every square
Connecting the checkpoints is only part of the challenge. Your route must cover the entire grid exactly once.
How Number Trail works
Number Trail is a path-finding logic puzzle. Begin at the cell marked 1, then move one square at a time up, down, left or right. Pass through each numbered checkpoint in ascending order without visiting a square twice. The puzzle is complete when all squares are included in one continuous trail.
For smaller boards, try 4 × 4. For a longer challenge, select 5 × 5 or 6 × 6. Daily puzzles provide a repeatable challenge, while Practice lets you start a fresh board whenever you like.
Frequently asked questions
Can I move diagonally?
No. Each move must connect two squares that share an edge.
Do I have to fill every square?
Yes. A completed trail visits every square once and passes all numbered checkpoints in order.
Can I play on mobile?
Yes. Tap neighboring squares or drag your finger along the path.
When does the daily puzzle change?
