An Even Odd Sudoku is a variant of the normal sudoku with an extra tip. There are squares or circles in certain cells with the following meaning:

• SQUARE : this should include an even digit.
• CIRCLE : This should contain an odd digit.

We know that each row, each column and each subgrid contains the digits from 1 to 9. This means four even digits: 2 - 4 - 6 - 8 and five odd digits: 1 - 3 - 5 - 7 - 9.
