Tangled Sudoku Puzzles to print

60,000 free entangled Sudoku puzzles made from four nested grids

A Sudoku Tangled is composed of four overlapping sudoku grids with the appearance of a spiral.

The puzzle contains 72 central boxes, common to two grids. This feature brings a new difficulty that may be of interest to players accustomed to ordinary puzzles. See below: Peculiarities of Tangled Sudoku Puzzles.

The rules of the game are identical to a classic sudoku. By logic and deduction, you need to find nine different digits per zone, column, and line for each 9x9 grid.

Each puzzle has only one solution. All of our tangled puzzles are solved by a sequence of logical reasoning. No random hypothesis will be necessary to arrive at a solution.

There are 60,000 puzzles presented in three levels and two shapes.
 Levels: expert, confirmed, beginner.
 Shapes: asymmetrical and symmetrical.

To better distinguish the grids, there are three modes of printing:
  •   White backdrop.
  •   Shaded backdrop.
  •   Colorful backdrop.

 Peculiarities of Tangled Sudoku Puzzles 

Generally none of the 9X9 grids can be solved in isolation. Some cells can only be found by concomitant reasoning on two 9x9 grids.
This feature is located mainly in the beginning and middle of the game.

 Symmetry or asymmetry of tangled grids 

A tangled puzzle sudoku is symmetrical when a rotation of a 180° angle, does not change the location of the boxes of the problem statement.
