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, 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.
- 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.

Ratings and Reviews
Not always, but frequently the app loses your game if you stop to take a phone call or look at something else. I was almost finished with the daily expert puzzle this morning that I’d spent over 45 minutes on when I got a phone call. When I went back to the app I was presented with the same puzzle, totally blank. Aggravating. I certainly wasn’t going to start all over again.

Needs a couple things to be 5 stars
First, great game! The ‘hard’ levels are actually hard and challenging, which is perfect for waking up with my morning cup of coffee. And the ads between games are short which allows you to play on fairly quickly.
2 requests to make this a 5 star game. First please give the game a landscape orientation option. When I’m traveling this would allow me to set my iPad on a tray table and enjoy the game instead of holding it in my hand all the time.
Second, please please please stop accepting banner ads that have movement! I don’t mind a banner ad at the bottom of my screen while I play, but lately there is a slots game you’re allowing to advertise and it demo rolls the slots every 2-3 seconds. The constant movement is incredibly distracting and causes my timed games to be much slower! Please make your banner ads static images.
Those 2 things and thus becomes the absolute best version of killer sudoku in the App Store!

Notes are changed
I enjoy the game but there is a problem with the advanced notes feature. If I return to a partially completed game, the notes will not be the same as when I left. There will be numbers there that I had previously deleted.
Same with getting a hint. I once made the mistake of getting one and it completely filled on all of the numbers on the notes wiping out the progress I had made.
I have taken to photographing what the board looks like when I leave so I can return it to that state when I resume the game. There has to be a better way.
