Killer Sudoku Free 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 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.

Updates remove features. I absolutely loved the app. I could play through the backlog of daily puzzles, but when it updated, my progress and trophies were wiped out. Now, you watch an ad to play any previous daily puzzle, in addition to the multiple ads that show up and interrupt the game. I don't need a sudoku app to have weekly bug fixes, events, or features, so the justification of 'making a living' off ad revenue is asanine. I tend to pay 1-3 dollars to remove ads, $15 is not worth it.

Hi, sorry for such inconvenience. The data are stored locally on one device. If you uninstalled before then reinstall the update version, all of them may get lost. As a startup, we have to survive by integrating with ads. We have forwarded your feedback about "Price" to our team. If anything else, please contact us at killersudoku@fungame.studio.

I really like this game a lot and have been playing it for quite a while. I am happy that they allow you to go back to previous daily challenges again. Even though you have to watch an ad I think that is more than enough to pay them and I get to play my puzzles. Also if you don't like ads then feel free that there is an ad free option in the settings menu. Over all great free to play game. If you don't like ads why come looking for a free to play game.... Just saying. Anyways great work devs 👍

Don't let the name fool you, by adding the math portion to a regular sudoku they actually made it easier! Instead of using logic threads to narrow down the answers, you just need to know which numbers add to the correct answer. The combinations will be almost obvious, especially if the row, column, or 3x3 box already contains numbers that could be used for the addition, narrowing down your choices. I only downloaded it to practice my mental addition.
