Leave a Review SumSudoku
Great game, great company
I have every app made by Conceptis. I enjoy every one. Sum Sudoku has great features, my favorite one is the ability to see the numerical options for the totals. I like that, for a reasonable sum, I can get another pack in my level of difficulty.Koasmom
Very enjoyable and as challenging as you want
This game is nicely designed, free of gaudy frills and very user friendly. It has an accuracy checker, if you want to use it, as well as possible number combinations visible at the click of a button. And with various levels of difficulty you can choose your challenge level. These Conceptis puzzles are excellent and a joy to do.Show lessabigail alligator
Just one thing needed
I wish there was a way to automatically add all nine possibilities to a square instead of having to enter each number separately. Otherwise, love the app.mcd1262mld
Excellent
It would be very nice if I could cross out the pencil numbers myself. The game makes too many decisions for me by doing that. Also, if you make a mistake, you have to go and re-work all the pencil marks!Brer Rabbi
Most Challenging
I very much appreciate that all the Sudoku related games by this developer are made with the symmetry of true Sudoku. A rarity in computer generated apps.
Of all the games by this developer, this game is the most challenging for me. I only wish the tools had more features that allow for eliminating possible entries or for checking pencil marks.Show lessPuzlFan
great mental workout!
I am addicted to these puzzles morning -- they keep my mind active and engaged and improve my logical thinking skills.periatetic
Great app but
This latest update shrunk the numbers to pick from and I don’t like it. If anything give us the option to restore the size please.Gggilguy
Concept is SumSudoku
Please, make an app for Sumoku! There is nothing in the web for Sumoku, except one article on solving the puzzles. I know it is very similar to this killer sudoku but it is not the same! Please!
I’m enjoying this app very much.cuentacuadros
Absolutely Brilliant
First came across Conceptis Sudoku in a daily calendar; the app is much better because I don’t have to stop at one a day!TheLibraryGoddess
Excellent game for killer sudoku addicts
Endlessly different killer sudoku puzzles with a variety of difficulty. Checking along the way that you are right is helpful but if you area purist you can ignore this feature.Nottooslim
