Hidoku Game

Hidoku is a Japanese logic puzzle game in which you have to find a path on a diagram that goes through all the squares exactly once in the correct order. In general, Hidoku is very similar to sudoku, and is sometimes called a number snake. The diagram is filled with numbers from 1 to the number of cells in the diagram, each number is used exactly once, and consecutive numbers must be orthogonal or diagonally adjacent. Hidoku starts with a partially filled grid of numbers. The grid can be of any size and shape.

Your task is to fill the grid with consecutive numbers that connect horizontally, vertically, or diagonally. The game ends when you connect all the cells to complete the numerical sequence. The first and last numbers of the sequence are always indicated. They are marked with an extra ring around the number. Each Hidoku puzzle has only one solution.

How to play?

Click on a blank cell to place a number, and then a guessed cell to remove it, if necessary. Use the number line at the bottom of the screen to change the numbers. You can also click and drag up and down anywhere in the background to change the numbers. Tap the "expanded" cell to toggle between the next and previous number.
