Instruction:
Apply classic sudoku rules. Each 3x3 box is also a grid for a Tic-Tac-Toe game. A game is won by placing three odd digits or three even digits in a horizontal, vertical or diagonal line. Each 3x3 box contains exactly one winning combination and this combination is marked by a grey line.
