About this game

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.

Good game. Some solve fairly easily, others I just can't do. I haven't figured out what the colour 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 highlited 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.

Good killer sudoku app ads are unobtrusive and works well. A bit annoying that you have to switch from pencil to pen but once you get used to that it is an enjoyable game. Changed rating as more recently keeps getting stuck on the start up screen - this seems to happen when you don't have a WiFi connection (as mobile data was on with a signal) and it can stay this way for days - most annoying ☹️

This app is so tiresome, dull and unimaginative. The lack of multiple cells selection and summation is suspecious. 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!
