A Glimpse into SumSudoku: Killer Sudoku
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 9×9 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 3×3 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.

User Reviews on SumSudoku: Killer Sudoku
Looking for more information? Read a comprehensive review of SumSudoku: Killer Sudoku below:
We’ve been playing this app for ages and it never gets old. We have a bunch of other puzzle apps and Conceptis apps are our favorites.
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. We like that the game gives your time, and you can restart a puzzle to try to beat your time.
We can now work on these puzzles.
Conceptis makes the BEST sudoku apps. They dont 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.
We love this app. We are new to SumSudoku and find their easy and medium versions challenging and fun. We are hooked on them. We would like to have a DAILY bonus, not just weekly. We would like to be able to select difficulty levels for the bonus game.
Some killer Sudoku apps will try to squeeze you for micropayments. And they have no features to let you choose how you want to play. They make things naturally difficult and make you buy undo and other helpful tools. But this one is honest. They sell you groups of puzzles if you want to buy them. And when you buy them, you really own them! You can reset them all and do them again later if you want. This app has great tools and they let you use them all or none. You choose how you play.
We have been using this app for years & appreciate this developers sense of challenge, fun and respect for users privacy.
Anything Conceptis is worth getting. We 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. We buy more packs of puzzles as we need them and often we just repeat the same puzzle packs because Im an ordinary person and its not like we have these puzzles memorized. Im a puzzle nerd and have tried many other apps by other developers but Conceptis is the best.
Although this is not a flashy app, we really enjoy it. It is pure game with simple function (but the game certainly is not simple.) The best part no ads ever! We play it almost every day.
We find regular sudoku puzzles to be too boring at this point, so these puzzles are great at keeping things challenging. We go back and forth between the hard and killer levels, and we find this app more enjoyable and better organized than other apps we have tried.
It would be nice for the weekly bonus puzzles to reflect the highest level of difficulty, or at least the 2 highest levels of difficulty the player is using. If you increase the number of puzzles from 30 to 45 or even 50 for the $1.99 it would be great. This is a very good logic and strategy game that is very helpful to maintain brain health. Its appropriate for all age groups. Please decrease the cost. We bet you would sell even more puzzles because we would not have to keep replaying the same games over many times. Do the math evaluate the bottom line effect because money is tight for everyone. Please pay it forward. Its a great game. The update you recently did adding the hint is excellent! Thank you!
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???
We like these types of puzzles, but the hard level does not supply any starting values. Perhaps we have not figured out how to solve them yet, but so far we can only solve these by making generous and unsatisfying use of the guess and check method, rather than just logic.
It never stops asking you to rate/review it. Never. Among the 6 Conceptis apps we have, we’ve had to hit No well over 100 times. Every single time they update it and then some. Edit: it asked again Edit 2: it asked again Edit 3: it asked again Edit 4: it asked again Edit 5: it asked again.
The new border around each asymmetrical 9-numbered sectionIts too much. What was wrong with the border thickness before?
If you love a challenge, this game is addictive!! Im addicted. Nuf said!
We’ve used this app for killer sudoku for a long time now and it only gets better with each update. The option to autofill the numbers has been great, so has the ability to cross off the fills that you know won’t work. We really like the newest update with the assistant that shows you the best next step. It tells you the name of the technique and highlights what to look at. We thought we knew all the tricks but it’s taught us a few new ones.
This variety of Conceptis puzzle is our absolute favorite. We enjoy every minute we spend, and we spend a lot!
Adds an extra layer of difficulty onto Sudoku, and is a really creative and interesting spin! The app works wonderfully, its very intuitive and we’ve encountered no bugs. No ads either, which is very refreshing.
We swear, we could get any app from this team and have a blast. This is just about the hardest logic puzzle we’ve played, and it’s great fun. Take it from someone who’s been playing Conceptis puzzle games for almost a decade!
Nothing as satisfying as completing a 45 minutes or more pure logic exercise like what these puzzles give you.
Hours of sudoku fun for super cheap. We spent $ on 3 package of $2 each so now we have over 100 puzzles we can play over and over and never feel like Im playing the same one twice.
So much fun. If you like kakuro puzzle, play this one too!
Love this app. Its the only one of its kind for SumSudoku.
We have a lot of conceptis apps, and we always appreciate how many free puzzles they come with to get you started and how cheap buying additional puzzle packs is. SumSudoku is nice because the puzzles take a lot longer than many of the others – we might be able to do a Hard Nurikabe in 10-15 minutes but a few of the Easy SumSudokus take that long and many of the Hards take a half hour or more. The features included are super helpful – being able to put in number possibilities that automatically disappear when you put another number in, seeing all the instances of a certain number highlighted, etc.
Great puzzles, just the right level of difficulty to be interesting, but not frustrating.
We play this daily and love it. Our favorite variation of Sudoku. Our one wishlist item would be dark mode. At night it is so bright and no color change options available.
We’ve been playing for almost a year and still havent needed to buy more puzzles but even if we did need to buy more puzzles itd be worth the money to buy them.
This is the one game app we have paid money for. We woke with words so taking a break by playing with numbers refreshes our brain. Keep adding more, please. $1.99 for at least 12 hours is a steal.
