# NINE BALL SUODKU ONLINE

 1 2 3 4 5 6 7 8 9
 LEV   1 (2) PUZ

Nine Ball Sudoku is a new variant in which the sudoku field contains colored cells in the form of a ball. The numbers that must be entered in the colored cells are related to the number 9. Hence the name Nine Ball Sudoku.

We will systematically go over the rules for this new variant:

• In the colored cells from rows 2 to 5 you will find the numbers 1 to 9.
• In the colored cells from rows 5 to 8 you will also find the numbers 1 to 9.
• Number 9 in a colored cell is always opposite the other 9.
• The sum of the other opposite colored cells is always 9.
• There are also numbers outside the sudoku field. These are the sum of the 1st and 3rd digit.

TIP: if the explanation is not entirely clear, than study the solution of the 1st puzzle thoroughly.
