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.
