This week's booklet

7 days in one PDF, Monday, October 26 to Sunday, November 1, 2026: a puzzle a page, the answers at the back.

How to play

Fill the grid so every row, column and 3×3 box holds the numbers 1 to 9 once.
The dashed outlines are cages. The numbers in a cage add up to the small total in its corner, and no number repeats inside a cage.
Start with the cages that can only be made one way: two squares adding up to 3 must be 1 and 2, and three squares adding up to 24 must be 7, 8 and 9.
Every row, column and box adds up to 45. Add up the cages wholly inside a box, and the squares left over make up the difference.
