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:
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.
