Killer Sudoku puzzle number 1,033 has been published, offering a challenging twist on the classic sudoku format. In this variant, standard sudoku rules apply, but with an additional constraint: the numbers in cells contained within dotted lines must add up to the figure shown in the corner of each cage. Furthermore, no number can be repeated within any shape formed by dotted lines.
How to Access the Print Version

Where to Find the Completed Solution

Understanding the Rules
Killer sudoku combines the logic of traditional sudoku with arithmetic. The grid is divided into cages, each indicated by dotted lines and a small number in the corner. The digits placed in each cage must sum to that corner number, and no digit may repeat within the cage. This adds an extra layer of deduction, as solvers must consider both row, column, and box constraints alongside the cage sums.
The puzzle is designed for enthusiasts of all levels, though the killer variant typically appeals to those seeking a greater challenge than standard sudoku. According to puzzle experts, the key to solving killer sudoku is to first identify cages with small sums or limited combinations, as these offer the most direct placements.
Additional Context and Tips
For newcomers, it is helpful to note that cages of two cells with a sum of 3 can only contain 1 and 2, while a sum of 17 in two cells must be 8 and 9. These fixed pairs provide a solid starting point. As you progress, you can use the '45 rule' – each row, column, and 3x3 box sums to 45 – to deduce values in larger cages.
The Guardian publishes a new killer sudoku daily, with puzzle 1,033 being the latest in the series. The puzzle is available both in print and online, and solutions are released on a schedule that ensures solvers have time to complete the challenge before seeing the answer.
