Try out the Daily Mail's most addictive brainteaser since Sudoku!

Love Sudoku? Can't resist a crossword?

Try out Kurosu, the latest Daily Mail puzzle. Highly addictive and utterly engaging, this is the fun alternative to Sudoku!

There are only 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.

Sounds easy, doesn't it? Think again! This book might look simple, but it's deceptively hard - it's the ultimate test of logic.

From easy and medium level, to the highest difficulty rated, Daily Mail Kurosu Volume 1 will offer hours of puzzling fun.

Perfect for both single players and groups!
