Most sudoku books give you a number and a grid. Landmark Sudoku gives you a place.
Every puzzle in every volume is named after a real landmark and carries a short, researched, sourced fact about it — where it is, and why it is worth knowing. One theme per book, one difficulty per book, so you always know what you are picking up.
The first three volumes
- Easy Great American Landmarks Sudoku 150 puzzles named for landmarks across the United States
- Medium World Landmarks Sudoku 150 puzzles, six continents
- Hard Space & Astronomy Sudoku 150 puzzles named for missions, observatories and objects in the sky
The first titles arrive in autumn 2026, in paperback.
This page will list them here as they publish, along with free printable puzzles — no email address required to download them.
