설명

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.

Excellent game but please lower prices on additional puzzles

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. It’s appropriate for all age groups. Please decrease the cost. I 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. It’s a great game. The update you recently did adding the “hint” is excellent! Thank you!

Thank you for your interesting and original ideas! we will look into them and see how we can improve the pricing of our puzzles

This is the best!

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.

Great challenge

I really enjoy this game but found I went through the free games pretty quick which makes waiting for the weekly update seem to take forever. Couple of suggested updates:
1. Let me change the basic colors, or at least provide options beside tan.
2. Instead of a pay as you go model let me have an option for a one-time pay option with all puzzles and updates included. New puzzles aren’t expensive but they will add up quickly.
