Progressive difficulty levels
The book starts with introductory puzzles, which are designed for beginners. These puzzles have fewer cells and often include several given numbers (also known as ‘givens’) which makes it easier for a solver to get started.

Each Sudoku puzzle begins with a set of given numbers, and the difficulty can range from simple to extremely challenging, catering to a broad spectrum of solvers with varying levels of expertise…Read&Listen More
