Series: The Big Book of Large Print Sudoku

Where hard books stop, this one starts

Some solvers outpace every puzzle book on the shelf. They want grids that lock up halfway through, patterns that take real insight to spot, and the deep satisfaction of cracking something that looked impossible an hour ago. This hardcover is for them: a big collection of expert sudoku in large print, built to be the toughest book on the coffee table.

Expert, measured

Every puzzle rated with Sudoku Explainer, a free program anyone can use to rate a puzzle again, and its Sudoku Explainer rating printed on every page. Puzzles run from lower to higher rating, spread across the Expert band, so you can pick your battle: a lighter grid on a busy evening, the summit of the book on a quiet weekend. Every puzzle has exactly one solution, reached by logic alone. At this level expect XY-wings, XYZ-wings and other advanced patterns, and plan on full candidate notation from the first move.

A sharper warm-up

Each sudoku comes with a calcudoku warm-up at a demanding setting. Most cages pair a target number with an operation, and at that strength the warm-up becomes a small puzzle in its own right, a brisk way to switch the analytical gears on. A how-to page at the front explains the rules, and the calcudoku answers sit with each sudoku solution at the back.

Built for long, deep sessions

Expert solving means lots of pencil marks, and large print gives every candidate room to stay legible as the notes pile up. The hardcover has a satisfying heft and holds its place on the shelf with dignity between sessions. Each puzzle names the page of its solution, and every puzzle printed with its own puzzle ID, so verifying a hard-won grid is quick.

For the puzzle champion

Give it to the friend who has finished every hard book you ever bought them, the relative who solves in pen, or the coworker who wants a project for the long winter evenings. It makes a standout birthday or holiday gift, and it pairs well with a fine mechanical pencil and a good desk lamp for marathon solving nights.

How experts work a grid

Most expert solvers fill in every candidate before the first placement, then hunt for cells with exactly two options and trace the chains that connect them. A good light, a fine pencil and patience do the rest. The reward for that patience is a breakthrough that clears half the grid in a few minutes.

Every main puzzle in this series appears in one book only, printed with its own puzzle ID so you can check. Give one volume for a birthday and the next for the holidays: each one is a fresh set.
