What's inside
- 150 classic 9×9 sudoku puzzles — 50 easy, 50 medium and 50 hard
- Two puzzles to a page, printed large enough to solve on a tray table
- Compact 5 × 8 inch format that fits a jacket pocket or a seat-back pouch
- Three clearly separated difficulty sections, so you can match the puzzle to the journey
- Complete solutions to all 150 puzzles at the back
- 105 pages, black and white, light enough to cost you nothing in a carry-on
A travel puzzle book has one job the big-format ones do not: it has to be solvable in bad conditions. Two puzzles per page instead of twelve keeps the grids large on a small trim, so you can still read them on a bumpy train or in the dim light of a late flight. And unlike a phone, it works from pushback to landing and never needs charging.
Who this book is for
Frequent flyers
Fits the seat pocket, survives a rucksack, and needs no wifi, battery or permission from the crew.
Commuters
An easy grid is about one train stop. A hard one is a whole commute.
Waiting rooms and queues
Airports, clinics, school pick-up. All three difficulties in one book means you always have the right length of distraction. New to the levels? Here is what separates easy, medium and hard Sudoku.
Good to know
- Trim size 5 × 8 inches — genuinely pocketable, unlike the 8.5 × 11 editions
- 150 puzzles, not a thousand: this is the one you take, not the one you work through at home
- Sections run easy, then medium, then hard, with solutions numbered to match
- Paperback, 105 pages
