Hard Hidato
Hard Hidato puzzles are 7×7. A number in the middle of the chain needs two different neighbours, one for the number before and one for the number after, which rules out cramped cells.

Hard puzzles need at least one of these techniques, and may use any easier one:
- Room on both sides
- A number in the middle of the chain needs two different neighbours, one for the number before and one after.
How to play
Hidato is a number path puzzle. Fill every empty cell so the numbers from 1 to the last form one chain: each number touches the next one horizontally, vertically or diagonally. Some numbers, including the first and the last, are given.
Every Hidato here has exactly one solution and can be solved by logic alone. The grid grows from 5×5 at Easy to 7×7 at Hard, and the level is set by the hardest technique the puzzle needs.
- Each number from 1 to the last appears once.
- Consecutive numbers touch, side by side or diagonally.
- The given numbers cannot be changed.
Playing on this site

- Tap a number you wrote to take it back; it becomes the current number again.
- Use the arrows below the board to pick another missing number.
- The numbers just before and after the current one are highlighted, so you can see where it must touch.
- Hint points out wrong numbers first, then names the next technique and shows where a number goes.
- Your puzzle is saved in this browser, so you can come back to it later.
