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.

Thoroughly addicted. A bit laggy sometimes & occasional bugs (currently showing multiple finished games as "in progress") but honestly this is my #1 game at the moment. Leaving off one star in the hopes the developers see this: Please adjust the "Daily Challenges" such that completion offers the option to play earlier unfinished Challenge(s) without having to tap through months & months.

The game is almost perfect, but the ads sometimes make it incredibly frustrating. To start a new game or continue an old one, you have to view an ad, and some of the ads are confusing to navigate. I've accidentally backed out of game right after picking it up, and quit the game instead of dealing with another minute long, hard to close ad. And they cost a shocking \$15 to get rid of.

I enjoy this game. I don't really play the quest games, one reason. Eing that if I exit all of my progress is lost and I have to start over. That gets old. I play the math game, the daily, and the relaxed. There is ads or buy option. (Kinda costly since it sounds like there are features that require ads so not totally ad free), but they do not pop up during the game. Just if you need to restart or after. That is nice.
