157 Large Print Killer Sudoku

157 Large Print Killer Sudoku brings all the sums-and-logic challenge of Killer Sudoku to large print. Each book has one puzzle per page, with cage totals you can read at a glance, so you can concentrate on the arithmetic and the logic rather than peering at small numbers.

There are three books with 157 puzzles each. Novice is the place to start if Killer Sudoku is new to you. Adept is for solvers who know the common cage combinations. Master is for experienced solvers who want large print without giving up a challenge.

The rules are classic Killer Sudoku: every row, column and 3x3 box holds the numbers 1 to 9 once, and the numbers in each outlined cage must add up to its total with no repeats. Because the cages carry most of the clues, the big print really helps: totals are clear and there's room to note the combinations you're considering.

Large print suits anyone who prefers bigger numbers and more space, for comfort, for eyesight or simply for a calmer solve. If you'd like more variety once you're confident, 1000+ Killer Sudoku Variants adds new grid sizes, Killer X and Killer Windoku.
