A Tangled sudoku puzzle is built with four 9x9 sudoku grids that overlap. These puzzles are a variation of samurai sudokus.
This type of problem has many boxes that are conjoined with two grids. See below: Characteristics of Tangled Sudoku puzzles.
The principles are similar to those of an ordinary sudoku. You need to find by deduction nine different digits by row, column and area for each 9x9 grid.
You have 60,000 problems presented with two forms and three levels.
Forms: Symmetrical or asymmetrical.
Levels: beginner, confirmed and expert.
Each entangled puzzle results in a unique solution. Moreover, all these grids obey a series of logical reasoning without multi-choice.
To better identify areas, there are three types of PDF:
* White background.
* Shaded background.
* Colored background.
Ces tangled sudoku are printable with the menu TANGLED SUDOKU and the link Print puzzles.
You will be able to choose prints in colored, gray and white.
Selection of PDFs: Our PDFs are sorted in ascending order of difficulty.
Reason for practicing Tangled Sudoku: The entanglement of the four grids proposes reasoning configurations that go beyond the ordinary framework of the classical Sudokus.
• Beginner Puzzles are fully solvable with the inclusive method while allowing other methods.
• Confirmed puzzles are fully solvable with the inclusive and exclusive method while allowing other methods.
• Expert Puzzles are fully solvable with inclusive, exclusive method and exclusive pairs.
For details about these methods of resolution, you can see: General help.
The 9x9 grids composing a puzzle can not be resolved, without taking into account the other joint grids.
This property fades at the end of the game.
A Tangled Sudoku puzzle is symmetrical when the figures of the puzzle statement are distributed in the same way around the center of the spiral.
You can distribute these grids on the condition that your web pages or your reproductions contain a link to our site.
