Killer Sudoku is a logical puzzle number game & brain game. To complete a puzzle, like the classic sudoku game, you can fill the grid with numbers; unlike the classic sudoku puzzle, you have to make sure that the sum of numbers in each cage (areas surrounded by the dotted lines) is equal to the number in the upper left corner of the cage.

If you are interested in playing number games or math puzzle games, this Killer Sudoku is exactly for you! If you'd ever played number games, such as Sumdoku, Sumoku, Addoku or Cross sum, come to try this one, too! It is an amazing combination of a sudoku puzzle, a KenKen and a Kakuro puzzle game.

Killer Sudoku may be a little bit harder than a classic sudoku puzzle game, no worries! We offer several balanced difficulty levels for beginners and advanced players! The game has the function to add or remove notes during gameplay. Did you make a mistake at the beginning? No worries, there are undo and hint functions! Get it back fast!

How to play:

1. Place numbers 1-9 into each grid cell exactly like in a classic Sudoku puzzle;
2. Different cages - groups of grid cells indicated by dotted lines;
3. The sum of all numbers in each cage should be equal to the number in the upper left corner;
4. The sum of all numbers of each 3x3 block, row, or column always equals 45;
5. Each cage, row, column, or 3x3 block cannot have the repeated numbers.

Features:

- Turn on the note mode to take notes like solving puzzles on a piece of paper. The memo is automatically updated itself while you fill in the cell.
- Find your mistakes and challenge yourself or use auto-check to see your mistakes in real-time
- Complete daily challenges and earn special trophies!
- Use free hints when you are stuck.

so far, so good. I had to download this version of killer Sudoku because I finished the last one in the hard selection. I know I should move on to the expert selection but hard seems to fit the bill. Maybe later on. in the meantime, once you play killer Sudoku, the regular Sudoku just doesn't cut it. Set up the settings for minimum interference and you've got yourself a good game. Thanks.

I've been playing this game for YEARS (You are NOT a "startup" anymore), supported through internment ads between games, which was fine. But in the most recent update, they added "game break" ads in the middle of a game whenever you complete a number. This is just a greedy money grab and completely breaks the relaxing flow of Sudoku, so I won't be playing anymore.

Love this game but would it be possible to auto fill in the single cage numbers, if present, at the start of expert level puzzles. Either that or prevent this type of expert puzzle generation. Also how many cross math puzzles need to be played before they become really challenging; I'm up to 380 and still haven't noticed any appreciable increase in the level of difficulty. "Hard" and "Elite" indications seem meaningless.
