Hidato Example.png Hidato Example Solution.png

Enter a number into each empty cell, so that, including the given numbers, all numbers from 1 to X appear exactly once. (X is the number of cells) Consecutive numbers must be placed in horizontally, vertically or diagonally neighbouring cells.

(Rules and example from WPC 2019 IB)

Rule variation[edit]

  • Rook Hidato: consecutive numbers can't be placed in diagonally neighbouring cells.

History of the puzzle[edit]

The name, meaning "my puzzle," was given to by Gyora M. Benedek (Israel), in 2007.

The rule itself is quite simple and possibly re-invented many times. Four-direction version has been at least since 1981, where the puzzles were written by Steve Wilson (USA).[1]
