Killer Sudoku (Daily Mail)
Sudoku where dotted cages tell you their sums instead of giving digits.
Every day: One dated killer sudoku a day, the same for every reader. New puzzle: Once a day; the start screen shows the date.

Killer Sudoku is the Daily Mail's daily cage sudoku. Few or no digits are given; instead, outlined cages show the sum of their squares, and the usual sudoku rules apply.
About Killer Sudoku (Daily Mail)
Killer Sudoku is one of about thirty puzzles on the Daily Mail games page, free in the browser with ads. Each one opens on a start screen that carries the day's date, and every reader gets the same puzzle that day.
The 9x9 grid follows sudoku rules, with every row, column and 3x3 box holding 1 to 9 once. On top of that the grid is divided into cages, each marked with a total: the digits inside a cage must add up to that number, and no digit may repeat within a cage. Working out which combinations make each total is the heart of the puzzle.
The puzzle opens behind the Daily Mail's consent screen, where you either accept personalised ads or buy an ad-free subscription. It suits readers who like a killer sudoku with their news and want a fresh one every day.
How to play Killer Sudoku (Daily Mail)
- Open Killer Sudoku on the Daily Mail games page.
- Read the total in the corner of each cage.
- Fill digits so each cage adds up to its total without repeating a digit.
- Keep every row, column and 3x3 box holding 1 to 9 once.
Tips
- Small and large cages have few combinations: a two-square cage of 3 must be 1 and 2.
- Every row, column and box adds to 45, so a box with one cage poking out tells you that square's value.
