How to Play Hidato

  1. Fill the 9×9 grid with numbers 1 through 81.
  2. Each consecutive pair must be adjacent — including diagonally.
  3. That's 8 directions: up, down, left, right, and all four diagonals.
  4. Given numbers mark waypoints along the path.
💡 Pro Tip
Diagonal adjacency gives you 8 neighbors instead of 4, making Hidato more flexible than Numbrix. Look for bottleneck cells with few open neighbors.

Frequently Asked Questions

How is Hidato different from Numbrix?

Hidato allows diagonal moves between consecutive numbers; Numbrix is orthogonal-only. Hidato paths are more flexible — and the extra freedom can make uniqueness trickier.

Can a Hidato puzzle have very few clues?

Yes — the path constraint alone is strong enough that some puzzles need only a handful of given numbers to have a unique solution.
