Just because the title of this book says 'Quick Solve Sudoku' doesn't mean that working on these puzzles will always be a breeze. The first few pages might be difficult because you're just getting used to the game. There are instructions to follow and seeing the patterns might not come easy. But the longer you play, the more you'll understand the game.
