## SumSudoku 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 in United States

### ***** "Love this game!"
Always fun, love the weekly bonuses!
-- Chipmunk702, 2025-03-09

### ***** "Great developer of truly ad-free logic puzzles"
I’ve never been disappointed by an app from this developer. Clean, functional, and good in-play instruction and guidance. Highly recommend.
-- mathjill, 2024-12-23

### ***** "Very enjoyable game!"
I love this game, takes some time to solve but this is the beauty of it, making my heart peaceful.

One function I wish it had was the number of sum is bigger or can be zoomed to see better.
-- Doulu55, 2024-08-04

### ***** "Almost perfect…."
Please add the ability to change the colors!  The tan grid lines are very difficult to see.

Like several other reviewers have mentioned, it would also be nice to be able to add all 9 notes to the blank cells at one time.  

Other than those two requests,I am very impressed with the app.  It is fun, challenging, and works flawlessly!
-- Lisaspieces1, 2024-08-01

### ****- "Good game but feature missing"
This is a good app, but we need to be able to tap once and drag across the notes number pad to add multiple numbers to a cell at once, rather than having to tap each number separately. As is, it's very inefficient and irritating.
-- Newm00, 2024-07-04

### ***** "My Favorite"
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.
-- fussguigdyy, 2023-11-28

### ***** "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.
-- BriGuy8008, 2023-09-29

### ***** "SumSudoku by Conceptsis"
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.
-- Mr. Don Quixote, 2023-09-18

### ***** "Great app"
I can now work on these puzzles
-- Not your mothers nickname, 2023-09-11

### ***** "It helps me keep my mind sharp"
Also helps with focus
-- adj183848318181, 2023-09-08
