Overview

So you finish every sudoku and sudoku variation you try, and you think you’re a master who can conquer any puzzle. Well, consider this collection a challenge! These 110 puzzles are so tough that you’ll be tearing your hair out . . . while you’re also having a great time giving your brain the best workout ever.

At first these Sudoku might seem like others you’ve tried, but the clues you get are very different. Some of the puzzles don’t give you very much information to work with—perhaps just a "more than" or "less than" sign. In other cases, the squares are connected by dotted lines and there’s only one sum as a hint. A few Sudoku are simply bigger; but bigger means harder, because instead of the usual 1-9 you have to figure out how 1-16 fits in the grid. Plus, you’ll find shaped puzzles, arrows and circles in the middle of the grid, and more.

To give you a fighting chance at winning our "bet," we also outline strategies, provide hints, and teach you a few techniques. So, sharpen your pencils and your mind, and start solving!
