About this Book

Solve 500 hard 9x9 Jigsaw Sudoku puzzles created for adult Sudoku enthusiasts. Instead of the regular square regions found in classic Sudoku, each puzzle uses irregularly shaped regions that introduce a different pattern of logical constraints. The consistently hard difficulty makes this collection suitable for experienced solvers who want a substantial set of irregular-grid Sudoku challenges.
