Opis

This is a text for learning how to solve Sudoku puzzles. One solves the puzzles by filling in all the numbers in the grid, such that only one number, 1-9, is present in the same column, block of 3x3 cells, or row. Information on how to do this is presented step by step in easy to learn format. By reading through the end of the first six chapters, one should be able to solve the puzzles rated "easy" in 10-25 minutes each. It should take an hour or two to do this reading, more if one closely inspects the diagrams. Next, information on solving the more difficult puzzles is presented. Appendix 2 discusses "brain exercise," which has been a mainstream scientific fact since 2003, supported by numerous studies in well-respected medical, psychological, and psychiatric journals. So if you don't know how to solve Sudoku puzzles, this book is for you
