Hard Sudoku Puzzle Book for Adults - 200 Extremely Challenging Puzzles

We attach no answers in this book as it is for more advanced players. This means you either figure it out or you don't. Try until you become skilled enough to solve them all and have fun in the challenging process. And don't worry, we can provide you the answers by email if you really need them.

Features:

- 200 extremely hard puzzles

- Big grids for easy solving

- With wider inner margins in all the puzzle pages, you can easily rip out or cut them

Since there is no official rating standard to identify the complexity of sudoku puzzles, and this one is by far the hardest level we can provide, you can check the one on the cover to see if it meets your expectation before you buy.
