Times Books The KenKen 4: The new brain-training puzzle phenomenon

The book is kind of nice but as a beginner I found it a bit too hard and it only has 4-5 easy puzzles and the type of paper used, makes the outline of the boxes get erased while erasing your mistakes and the paper tears after a few mistakes even if you try and erase it softly bit overall the book has nice puzzles to challenge you.
