Hidato: how to play, rules & tips
Play Hidato free online, the number path puzzle. Fill the grid so the numbers run 1, 2, 3 and up in one unbroken chain, with each number touching the next in any direction, including diagonally.
How to play Hidato
Some squares already hold numbers, always including 1 and the highest number. Your job is to fill every empty square so the full grid forms one chain from 1 to the top number.
Each number must touch the next one. Touching counts in all 8 directions: up, down, left, right or diagonally.
Tap a square and enter its number. Erase clears a square and Reset starts the board again.

Each board was checked by a solver to have exactly one solution. The free Hint places a correct number at any time, and retries are unlimited.
Hidato tips
- Look for small gaps first. If 12 and 14 are given, 13 must go in a square that touches both of them, and there are often only one or two.
- Count the distance. If 20 and 25 are given, the four numbers between them must fit in a path of exactly that length.
- Corners and edges have fewer neighbors, so the chain has fewer ways to pass through them. Check them early.
- Watch for dead ends. Every square except 1 and the last number needs two chain neighbors, one before and one after. A square with few open neighbors has very few options.
- Work outward from the given numbers in both directions rather than only counting up from 1.
