EVERY day in the Mail you can play Kurosu, the most addictive brainteaser since Sudoku. There are two rules: 1: Fill in each space with either a nought or a cross so there are no more than two consecutive noughts or crosses in any row or column. Important note: diagonals don’t count.
2: Each row and column must contain three noughts and three crosses.
