Easy sudoku puzzles with explained solutions

The hundred examples proposed in this booklet is easy; indeed, the single putting rule is sufficient to finish them. Examples 1 to 52, very easy, is written for beginners who must complete unities with only 1, 2 or 3 free cells. Examples 53 to 80 are easy, but solvers must complete some unities with four free cells. Examples 81 to 100 are more difficult. Solvers must first reduce the number of free cells by trying to put each symbol in boxes, before completing unities. Sometimes, all free cells vanish, so no completion is necessary (examples 81 to 88). In many examples, they must partly complete some unities. After finishing this booklet, readers become confirmed gamers and can solve puzzles in my two previous books: - New Sudoku puzzles with explained solutions. - How to finish quickly Sudoku puzzles.
