Common questions
What does SER 8.5 to 9.0 mean?
SER is the Sudoku Explainer rating, a scale for Sudoku difficulty. The 8.5 to 9.0 band is extreme territory meant for advanced adult solvers. Each puzzle in the book lists its own rating.
Are the answers included?
Yes, answers in back cover all 200 puzzles. Each puzzle has one solution to check against when you finish.
Why four puzzles per page?
The 8.5 x 11 inch trim is large enough to hold four grids at a workable size. That keeps the book compact for solvers who go through many puzzles. A large print, one-per-page edition is available separately.
