Killer Sudoku

Cages with sums instead of given numbers.

Let's Play

About the game

Sudoku meets arithmetic. Dashed cages cover the grid, each with a small sum in its corner, and the numbers inside add up to it. The harder puzzles start with an empty grid: everything follows from the sums.

Rules

Fill the grid so that every row, every column and every 3×3 box holds each number from 1 to 9 exactly once.

The numbers in each dashed cage add up to the small sum in its corner, and no number repeats inside a cage. Hard and expert puzzles start without any given numbers. Tip: every row, column and box adds up to 45.

Every puzzle has exactly one solution, so it can always be found by reasoning, without guessing. A number that breaks a rule turns red.

How to play

  1. Tap a cell, then a number below the board (or type it).
  2. The numbers in a dashed cage add up to its small sum.
  3. No number repeats inside a cage.
  4. Not sure? Switch on notes and pencil in the options.
