Very very nice set of books for young children.Brought it for my grandson who is 6. It keeps him busy and engrossed.

Quality of book is good, I am solving killer sudoko level 4, felt it can be even more hard. The font sizes are decent, so it's easy for Even elders to use

This is rhe best product I have ever bought as it has an amazing quality. It worth buying but the size I was expecting was big but that’s just a minor thing.

Liked it !!

Level of these Sudoku are a bit tough... Even easy level Sudoku are equivalent to medium / hard level in many apps on play store.. So it's good exercise for your brain...

Bought this for my mom because she likes solving Sudoku puzzles, and it's a size wise it's a smaller set of books each so she can carry it around with her. Each book has more than a 100 puzzles each with increasing difficulty, also large font for the numbers is great. Great product all-in-all.

Fun and relaxing.
