180 Pocket Sudoku Variations

Sudoku variants in a travel-friendly size.

180 puzzles per book · Pocket size

180 Pocket Sudoku Variations is compact enough for a bag or coat pocket, which makes it ideal for trains, planes and waiting rooms. Each book holds 180 puzzles that mix classic Sudoku with two popular variants, Sudoku X and Windoku.

Sudoku X adds the two long diagonals, which must also hold the numbers 1 to 9. Windoku adds four extra shaded boxes with the same rule. Both give familiar Sudoku a fresh twist without making it complicated.

There are four books: Easy to Hard, Medium to Very Hard, Hard to Extreme, and Easy to Extreme, which mixes every level in one book. Choose the range that suits you, or Easy to Extreme if you're buying for someone and aren't sure of their level.

If you'd prefer classic Sudoku only in the same size, see 240 Pocket Sudoku. For the same variants plus Asterisk and Center Dot in a full-size book, see 1500 Sudoku Puzzles & Variations.
