Publishers of Landmark Sudoku

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

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.
