Note: this is not in conjunction with my Minesweeper puzzles
In all honesty, I don't know why I decided to look up this type of puzzle since I also have never heard about it, and there doesn't appear to be any puzzles on here mentioning it, so I don't know why I looked it up.
From Wikipedia:
Hidato (Hebrew חידאתו, originating from the Hebrew word Hida = Riddle), also known as "Hidoku", is a logic puzzle game invented by Dr. Gyora M. Benedek, an Israeli mathematician. The goal of Hidato is to fill the grid with consecutive numbers that connect horizontally, vertically, or diagonally.
From the section "About the Puzzle":
About the puzzle
In Hidato, a grid of cells is given. It is usually square-shaped, like Sudoku or Kakuro, but it can also include hexagons or any shape that forms a tessellation. It can have inner holes (like a disc), but it has to be made of only one piece.
What is the goal of Hidato?
To fill the grid with a series of consecutive numbers adjacent to each other orthogonally or diagonally. All tiles are required to be filled in.
"In every Hidato puzzle the smallest and the highest numbers are given on the grid. There are also other given numbers on the grid (with values between the smallest and the highest) to help direct the player how to start the solution and to ensure that Hidato has a single solution."
However, the above conditions of the smallest or highest numbers sometimes are relaxed. When they are, only the numbers are given, not their position on the grid.
Every well-formed Hidato puzzle has a unique solution. A Hidato puzzle intended for human solvers should have a solution that can be found through logic and deductions. However, it is possible for there to be difficult puzzles, even of small size.
