The Big Book of Medium Sudoku, Volume 1

Months of satisfying solving

Medium sudoku is where the game gets interesting. The grids ask for more than spotting the obvious, yet they reward steady reasoning with a clean finish, and a big book of them means the right puzzle is always within reach. This hardcover is built to be the household puzzle book, the one that lives by the armchair and gets opened every day.

A level you can count on

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, so the book opens with a friendly stretch and climbs toward grids that ask for real thought. Every puzzle has exactly one solution, reached by logic alone. Expect to hunt for hidden singles across rows and columns, spot the one digit that fits a stubborn cell, and occasionally use a pair of candidates to break a corner open.

Warm-ups with a twist

Beneath each sudoku sit two small calcudoku puzzles, a gentle one and a slightly trickier one. Each cage shows a target, most with an operation, so the warm-ups mix a little arithmetic into the logic and make a lively start to every page. The how-to page at the front explains the rules in plain language, and the warm-up answers appear beside each sudoku's solution at the back.

A book that feels good to hold

The hardcover has a reassuring heft and looks smart on a side table between sessions. Large print gives every digit room to breathe, with cells big enough for neat pencil notes. Each puzzle names the page of its solution, and every puzzle printed with its own puzzle ID, which makes checking quick and keeps your place easy to find.

Who it is for

It suits the daily solver who wants a reliable challenge, the reader moving up from easy books, and the friend who likes to keep a pencil and a puzzle by the window. As a gift, it fits birthdays, holidays, retirements and get-well baskets, and a hardcover always feels a little more special to unwrap than a stack of loose puzzle pages.

Solving with friends

A big book like this is easy to share. Couples race on facing pages, book clubs trade favorite grids, and grandparents walk grandchildren through their first medium puzzle one deduction at a time. The printed ratings make it simple to suggest a page that fits each person.

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.
