 Playing a Sudoku puzzle 






Sudoku Z has 1,000,000 different puzzles, each one divided into five difficulty levels:

  • Beginner
    • 

  • Easy
    • 

  • Medium
    • 

  • Hard
    • 

  • Evil
    • 

    

    
If you get stuck and need some help or just want to assure that you are on the right track,
Sudoku Z offers you some hints.
There are three different levels of hinting to choose between.
The first level just checks that you haven't made any mistakes.
If you have, it will show you one of them.
Next hint level will also show you a cell to focus on.
The third hint level will not only show you that cell, it will also reveal the number to place there.

    

    
Sometimes when trying to solve the puzzle, it's convenient to add some notes during the process.
Sudoku Z allows you to tag each empty cell with possible numbers.

    


    

    
Sudoku Z keeps the statistics for each difficulty level, the best time and the average time spent on solving the puzzle.

    

    
It's not always that you can bring a computer.
Therefore, Sudoku Z allows you to print the puzzle on paper.

When creating your own puzzle, Sudoku Z can show you cells that are redundant (in purple).
I.e. the puzzle will still remain valid, if one of the marked cells is removed.
It will also show you all possible numbers in each cell.
Numbers that are certain are highlighted in blue.
I.e. you can logically determine that this is the correct number in this cell.

    

    
There are some enclosed puzzles that you can load. One group of really hard puzzles is called 'Madly evil'.
Another group is called 'Patterns'.
In this latter group of puzzles, the numbers are formed in a nice symmetrical pattern.
