Number Path Solver: rules, how to use it, tips

Draw one path from 1 that passes through every square once, reaching the numbers in order and ending on the highest number.

The rules

Move from a square to a neighbour above, below, left or right — never diagonally.
Visit every square exactly once.
Start on 1, reach 2, then 3, and so on; finish on the highest number.
Don’t cross a thick wall.

Using the solver

Choose the size, enter the numbers and walls (or press Sample).
Press Solve and follow the path from 1: forced moves, cut-off areas, dead ends, and look-aheads.

Tips

Corners and pockets. A square with only two open neighbours must be passed straight through them — unless it’s the start or finish.
Don’t cut the board. If a move would split the unvisited squares into two separate areas, it can’t be right: the path could never come back.
Dead ends. Leaving a square with only one way in is fine only if it’s the finish.
Count to the next number. Between two numbers, the path needs exactly enough room to cover the squares it must pass on the way.

Questions

Is this like the daily path puzzles?

Yes — one path, every square, numbers in order, and walls, just like the popular daily versions.

What do the walls do?

A thick line between two squares means the path can’t step directly between them.

Is there always one answer?

Yes — every puzzle here is checked to have exactly one path.

How do I solve one from an app or book?

Open the Number Path Solver, type the numbers, add any walls and press Solve.
