For solvers who've outgrown "easy."

If medium sudoku barely slows you down anymore, this is the one. 100 genuinely challenging sudoku puzzles, built for solvers who want to work for the win - advanced techniques, tighter logic chains, no shortcuts. And because a serious puzzle deserves a serious-looking book, it comes wrapped in a bold, hand-illustrated cover that looks nothing like the puzzle books you've outgrown.

This is sudoku as it should be at this level: demanding, but never unfair. Every puzzle has been checked to ensure exactly one valid solution - no guesswork, no dead ends, just pure logic.

In this book, you'll find:

100 hard sudoku puzzles, built for experienced solvers who want a real challenge
Every puzzle solvable through logic alone - no lucky guessing required
Large 9-9 grids, one per page, so you can focus on the puzzle, not the print
A full answer key for every puzzle
A striking cover that looks as sharp as the puzzles inside
And much, much more

You don't need to prove anything to anyone - but if you want puzzles that finally push back, this is where you'll find them.
