304 puzzles. One solution each. Zero filler.
Sudoku Challenge delivers four clearly labelled tiers — 76 Easy, 76 Medium, 76 Hard, and 76 Expert. Every grid was generated from a complete solution and carved down while a solver proved that exactly one solution remains. Easy and Medium are additionally verified to need no guessing at all: singles carry you through. Hard and Expert demand deeper logic.
Inside:
- 304 puzzles across four difficulty tiers with divider pages
- Every puzzle verified to have exactly one solution
- Easy and Medium guaranteed solvable without guessing
- Full solution grids for every numbered puzzle
- Large 8.5 x 11 pages, 176 pages
From relaxing warm-ups to grids that fight back — the difficulty on the label is the difficulty in the book.
