Sudoku X - 200 Hard to Master Puzzles 6x6 (Volume 18) (Paperback) (ISBN-13: 9781695798991)

Sudoku X also called Diagonal Sudoku.

The puzzle is a 6x6 grid made up of 3x2 subgrids (called "regions").
Some cells already contain numbers, known as "givens".

The goal is to fill in the empty cells, one number in each, so that each column, row, region and diagonal contains the numbers 1 through 6 exactly once.

Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.

The puzzle book contain:
- 200 Puzzles
- Handy 6 x 9 inch Book Layout
- 2 Puzzles per Page
- Ideal for Experts

In the book you will find a description and examples of solutions for all puzzles.
The book is for those who like logic and math problems. Decide, developing and improving.
