Description

Play a crossover variation of Sudoku and Kakuro! SumSudoku, also known as Killer Sudoku, are addictive logic puzzles best described as a cross between Sudoku and Kakuro. Using pure logic and simple add/subtract calculations, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.
Each puzzle consists of a 9x9 Sudoku grid containing areas surrounded by dark borders. The object is to fill all empty squares so that the numbers 1 to 9 appear exactly once in each row, column and 3x3 box, and the sum of the numbers in each area is equal to the clue in the area's top-left corner. In addition, no number may be used in the same area more than once.
The game includes helpful features such as showing possible sum number combinations in an area and pencilmarks to make temporary placement of numbers in the grid. To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.
For more fun, SumSudoku contains no ads and includes a Weekly Bonus section providing an extra free puzzle each week.

SumSudoku Reviews

My Favorite

fussguigdyy on

This variety of Conceptis puzzle is my absolute favorite. I enjoy every minute I spend, and I spend a lot! Don’t like the new color schemes. Even turning off black mode. There’s no distinguishing between completed sets and non completed sets, and the different grays now less appealing and harder to differentiate.

Conceptis is the best!

Conceptis makes the BEST sudoku apps. They don’t try to gouge you with MTX. They sell puzzles and when you own them they are ACTUALLY YOURS. You can reset them as often as you want and replay them. And they never have ads! This us what apps should be.

I love this app. I am new to SumSudoku and find their easy and medium versions challenging and fun. I am hooked on them. I would like to have a DAILY bonus, not just weekly. I would like to be able to select difficulty levels for the bonus game.

Great app

Good. Could be better

TheDudeCanRoll5 on

United States

Its a good app. Could be better. For example. Why do all of the areas to be summed have to be symmetrical with the other side of the puzzle???

Conceptis FTW

LittleDochy on

United States

Anything Conceptis is worth getting. I have all their apps (this one is a fav) and have played on them for YEARS. Simple apps, no fancy ads, just lots of puzzles. I buy more packs of puzzles as I need them and often I just repeat the same puzzle packs because I’m an ordinary person and it’s not like I have these puzzles memorized. I’m a puzzle nerd and have tried many other apps by other developers but Conceptis is the best.

Great game.

Dknkbn1981 on

Well designed game in terms of making the moves. Easy to switch between pen/pencil markings. And the puzzle levels are well defined. Easy is basic enough, medium is a little tricky and the hard puzzles are a real challenge. I like that the game gives your time, and you can restart a puzzle to try to beat your time.
