The rules to be applied are the same as a classic sudoku. You need to find by deduction 4 different numbers per row, column and region.
You have two levels.
Levels: Beginner and confirmed.
Each of our puzzles has only one solution.
All our problems are solvable by a sequence of logical reasoning. No multiple choice is useful for the solution of a cell.
Printing 4x4 sudokus
To distinguish better between areas, there are three types of print:
* White background.
* Shaded background.
* Colored background.
• Choose the appearance of the background of your 4 x 4 sudoku. "Colored background" is defined default.
• Choose the level of difficulty of your 4x4 grid. "Beginner" is defined default.
• Choose the number of 4x4 sudoku per page: 1, 2 or 4 grids per page. "One grid" is defined default.
• To print the solution of a 4x4 Sudoku enter the parameters of your grid in "Print on a page 1, 2 or 4 problemsor solutions of grid that you select" and check the option "Solution".
