Kropki Sudoku

Play Kropki Sudoku – a refreshing take on the classic Sudoku! Solve puzzles, train your brain, and have fun. It’s also known by such names as Kropki, Dots Sudoku and Kropki puzzle but in a nutshell it’s pretty much the same number puzzle. 

Kropki Sudoku is the variation of the classic sudoku. If there is a white dot between two cells, then the values in these cells differ by one. If there is a black dot - then the values differ by half. For numbers 1 and 2, there may be both white and black dot in neighbour cells. Because both rules are observed. If there is no dot between two cells then none of the two conditions must be fulfilled.

Kropki Sudoku is perfect for both sudoku beginners and pro sudoku players! You can choose a difficulty level that fits your goal best – an easy puzzle to relax and clear your mind or an expert level for a real mental workout.

🎓 How to play Kropki Sudoku:

    * Fill all rows, columns, and 3x3 blocks with numbers exactly like in classic Sudoku.
    * Numbers cannot repeat within a single row, column, or 3x3 block.
    * If there is a white dot between two cells, then the values in these cells differ by one.
    * If there is a black dot - then the values differ by half. For example (1 and 2, 2 and 4, 3 and 6, etc.)
    * For numbers 1 and 2, there may be both white and black dot in neighbour cells. Because both rules are observed.
    * All possible dots on the field are already exposed, this means that if there is no dot between the two cells, then their values can not differ by one and can not differ by half.
