Killer

How to play

Fill the grid so that every row, every column and every 3×3 box contains the numbers 1 to 9 exactly once, as in Sudoku. There are no numbers to start from. Instead, dashed cages split the grid, and the small number in each cage's corner is the sum of its digits. A digit never repeats inside a cage. The puzzle is also called Killer Sudoku.

Tap a cell, then a number; switch on Notes to pencil in candidates instead.
