Description

Killer Sudoku (also known as Sumoku, Sum Sudoku, Addoku, or Samunamupure) is a puzzle that combines elements of sudoku and kakuro. Despite the name, the simpler Killer Sudoku can be easier to solve than regular sudokus, depending on the solver's skill at mental arithmetic; the hardest ones, however, can take hours to crack.

A typical problem is shown on the right, using colors to define the groups of cells. More often, puzzles are printed in black and white, with thin dotted lines used to outline the "cages"

The objective is to fill the grid with numbers from 1 to 9 in a way that the following conditions are met:

Each row, column, and nonet contains each number exactly once.
The sum of all numbers in a cage must match the small number printed in its corner.
No number appears more than once in a cage.

Comments on Killer Sudoku for Android

★★★★☆ Mark Friesen · Jul 29, 2020

Good game. Some solve fairly easily, others I just can't do. I haven't figured out what the color shading is all about. Sometimes I get a group of numbers shaded with a purple background. What's this trying to tell me? Some numbers are highlighted with a blue background. A help reference section would be great. Sometimes if I've spent way too much time on a puzzle, it would be nice to confirm my progress with a check feature.

★★★★☆ hendra kwee · Jun 19, 2020

Nice apps. The problems are quite challenging. My suggestion is the apps should provide solution so that people can check what is their mistake if they could not get solution. I could nkt solve some problems and quite sure my logic is correct but no result is consistent. So I kind of doubt whether the problem is correct or not

★★★★★ Freya White · Feb 2, 2022

Really good game, some ads but not too bad. Never had hard any issues

★★★★☆ Susan Neal · Apr 4, 2020

Very good game slowly but surely getting my time down on these puzzles esp the extreme levels!

★☆☆☆☆ Nathan Peglar · Nov 15, 2025

Played this game for years. Since updating the game I can no longer access any of the higher levels I have completed. I am stuck doing all the levels again as I haven't completed the last 10 levels even though when you click on all the levels they say "you win" restart this game or play others. If this is not fixed soon I will just find another game as I am not doing these levels all over again.

★☆☆☆☆ Killian McCormack · May 23, 2020

Getting a network error on both Wi-Fi and data that won't let me start the game.

★☆☆☆☆ Andreia Khalil · Sep 7, 2021

This app is so tiresome, dull and unimaginative. The lack of multiple cells selection and summation is suspicious. Why do I have to manually notate, and/or add up a dozen cages? Maybe to make solving the puzzles unnecessarily more difficult, so you'd have to rely on the hints that you get for watching 30 SECONDS ad each! And the quantity of ads is unbelievable. This seems like a rip off!
