puzzle series · 2022
No filler, no padding, no half the book taken up explaining the rules. Pick a volume by how many puzzles you want and how long you want it to last. Every one has its solutions in the back.

Just Sudoku
Every volume runs from level 1, which you can do in front of the television, to level 100, which you cannot. Beginners and veterans buy the same book.
They differ in two ways: how many puzzles, and how many are printed on a page. Twelve to a page is compact. Six to a page gives you room to write. Mark 7 is the sampler, Mark 2 is the one that lasts a year.
