How to Play Numbrix

Fill the 9×9 grid with numbers 1 through 81.
Each consecutive pair (1-2, 2-3, ..., 80-81) must be orthogonally adjacent.
Move only up, down, left, or right — no diagonals.
Given numbers are clues — your path must pass through them.

💡 Pro Tip

Start from the given numbers and work outward. Where two givens are close (like 15 and 20), count how many cells the path needs between them.

Frequently Asked Questions

What's the difference between Numbrix and Hidato?

Numbrix uses only orthogonal adjacency (up/down/left/right). Hidato allows diagonal moves too, giving each cell 8 neighbors instead of 4.

Does the path always start at 1?

Yes — the path begins at 1 and ends at 81, passing through every cell of the 9×9 grid exactly once.
