What are Hidato (Number Snake) puzzles?
The objective of our Hidato-like (Number Snake) puzzles is is to form a continuous path of numbers from 1 to the (given) end number of the puzzle. This end number depends on the grid size. A 10 by 10 puzzles, for example, has 100 cells, so the objective is to connect the numbers 1 to 100. The grids are filled with the start number, the end number and some random clue numbers and it's up to you to fill in the missing numbers in such that they connect horizontally, vertically or diagonally (see the rules). The more difficult the logic puzzle, the less clue numbers are printed.
The Rules of Hidato or Number Snake
1. Fill in the missing numbers in the grids
The grids are divided into cells that are either filled in by a number or empty. The start number 1 and the end number of the Number Snake puzzle are printed). This end number can be 25, 36, 49, 64, 81, 100, 144 or 225, depending on the grid size (a grid of 10 by 10 contains 100 cells). The objective is to fill in the missing numbers.
2. Connect numbers in a continuous loop or path
All numbers in the grid need to connect. The 1 must connect to the 2, the 99 to the 100. The loop (or path) of numbers must be continuous and form a single chain of numbers. Number snake puzzles are based on logic and not on mathematics and will boost your logic brain power when you solve them.
3. Start and End numbers are printed in circles
In each grid the start and finish numbers (end numbers) are printed in circles. The end number depends on the grid size: a 5 by 5 grid has an end number of 25, while a 12 by 12 grid has an (12 x 12) end number of 144. Unlike our Numbricks puzzles, all the start and end numbers are given so that you don't have to do the math. Not that this would be difficult, but anyway.
4. Numbers must connect horizontally, vertically or diagonally
The numbers in the grid must connect either horizontally, vertically or diagonally. Unlike the Numbricks puzzles you are allowed to connect numbers diagonally (as shown in the example on the left). This does not mean that Number Snake puzzles are easier than Numbricks puzzles, but that it does add an extra dimension to the logic puzzle.

5. Each puzzle has only 1 solution
Each puzzle should have only 1 unique solution. Do you find any more possible number chains, please contact us. We will impose a large fine on our developer's salary.
